Press enter for default partition number. Press Enter key for default First sector. Type +10G to specify 10GB disk. After loading the desktop, click install Linux mint and the rest of the steps are the same as the above mentioned without any change, And this is how to install Linux on a virtual machine. Hope, you will take advantages of this article. Arch Linux is a powerhouse Linux distribution that offers a rolling release, so all of your software is always up to date. But with that power comes a bit of operating system installation complexity. In other words, installing Arch Linux isn’t easy but not impossible.
Brief: This tutorial shows you how to install Arch Linux in easy to follow steps.
Arch Linux is a x86-64 general-purpose Linux distribution which has been popular among the DIY enthusiasts and hardcore Linux users. The default installation covers only a minimal base system and expects the end user to configure and use it. Based on the KISS – Keep It Simple, Stupid! principle, Arch Linux focus on elegance, code correctness, minimalist system and simplicity.
Arch Linux supports the Rolling release model and has its own package manager – pacman. With the aim to provide a cutting-edge operating system, Arch never misses out to have an up-to-date repository. The fact that it provides a minimal base system gives you a choice to install it even on low-end hardware and then install only the required packages over it.
Also, its one of the most popular OS for learning Linux from scratch. If you like to experiment with a DIY attitude, you should give Arch Linux a try. It’s what many Linux users consider a core Linux experience.
In this article, we will see how to install and set up Arch Linux and then a desktop environment over it.
The method we are going to discuss here wipes out existing operating system(s) from your computer and install Arch Linux on it. So if you are going to follow this tutorial, make sure that you have backed up your files or else you’ll lose all of it. You have been warned.
But before we see how to install Arch Linux from a USB, please make sure that you have the following requirements:
Once you have made sure that you have all the requirements, let’s proceed to install Arch Linux.
You can download the ISO from the official website. Arch Linux requires a x86_64 (i.e. 64 bit) compatible machine with a minimum of 512 MB RAM and 800 MB disk space for a minimal installation. However, it is recommended to have 2 GB of RAM and at least 20 GB of storage for a GUI to work without hassle.
We will have to create a live USB of Arch Linux from the ISO you just downloaded.
If you are on Linux, you can use dd command to create a live USB. Replace /path/to/archlinux.iso with the path where you have downloaded ISO file, and /dev/sdx with your drive in the example below. You can get your drive information using lsblk command.
On Windows, there are several tools to create a live USB. The recommended tool is Rufus. We have already covered a tutorial on how to create a live USB of Antergos Linux using Rufus in the past. Since Antergos is based on Arch, you can follow the same tutorial.
Once you have created a live USB for Arch Linux, shut down your PC. Plugin your USB and boot your system. While booting keep pressing F2, F10 or F1dependinging upon your system) to go into boot settings. In here, select to boot from USB or removable disk.
Once you select that, you should see an option like this:
Select Boot Arch Linux (x86_64). After various checks, Arch Linux will boot to login prompt with root user.
Next steps include partitioning disk, creating the filesystem and mounting it.
The first step includes partitioning your hard disk. A single root partition is the simplest one where we will create a root partition (/), a swapfile and home partition.
I have a 19 GB disk where I want to install Arch Linux. To create a disk, type
Type “n” for a new partition. Type in “p” for a primary partition and select the partition number.
The First sector is automatically selected and you just need to press Enter. For Last sector, type the size you want to allocate for this partition.
Create two more partitions similarly for home and swap, and press ‘w‘ to save the changes and exit.
Since we have created 3 different partitions, the next step is to format the partition and create a filesystem.
We will use mkfs for root and home partition and mkswap for creating swap space. We are formatting our disk with ext4 filesystem.
Lets mount these filesystems to root and home
Since we have created partitioning and mounted it, let’s install the base package. A base package contains all the necessary package to run a system, some of which are the GNU BASH shell, data compression tool, file system utilities, C library, compression tools, Linux kernels and modules, library packages, system utilities, USB devices utilities, vi text editor etc.
Generate a fstab file to define how disk partitions, block devices or remote file systems are mounted into the filesystem.
Change root into the new system, this allows changing the root directory for the current running process and the child process.
Some systemd tools which require an active dbus connection can not be used inside a chroot, hence it would be better if we exit from it. To exit chroot, simpy use the below command:

Use below command to set the time zone.
To get a list of zone, type
Run hwclock to set the hardware clock.
File /etc/locale.gen contains all the local settings and system language in a commented format. Open the file using vi editor and un-comment the language you prefer. I had done it for en_GB.UTF-8.
Now generate the locale config in /etc directory file using the commands below:
Create a /etc/hostname file and add a matching entry to host.
127.0.1.1 myhostname.localdomain myhostname
I am adding ItsFossArch as a hostname:
and then to the /etc/hosts file.
To install a bootloader use below commands :
To create root password, type
and enter your desired password.
Once done, update your system. Chances are that you already have an updated system since you have downloaded the latest ISO file.
Congratulations! You have successfully installed a minimal command line Arch Linux.
In the next step, we will see how to set up a desktop environment or Graphical User Interface for the Arch Linux. I am a big fan of GNOME desktop environment, and we will be working on installing the same.
Before you can install a desktop environment, you will need to configure the network first.
You can see the interface name with below command:
For me, it’s enp0s3.
Add the following entries in the file
Save and exit. Restart your systemd network for the changes to reflect.
And then add the below two entries in /etc/resolv.conf file.
Next step is to install X environment.
Type the below command to install the Xorg as display server.
gnome contains the base GNOME desktop. gnome-extra contains GNOME applications, archive manager, disk manager, text editors and more.
The last step includes enabling the display manager GDM for Arch.
Restart your system and you can see the GNOME login screen.
A similar approach has been demonstrated in this video (watch in full screen to see the commands) by It’s FOSS reader Gonzalo Tormo:
You might have realized by now that installing Arch Linux is not as easy as installing Ubuntu. However, with a little patience, you can surely accomplish it and then tell the world that you use Arch Linux.
Arch Linux installation itself provides a great deal of learning. I recommend a few essential things to do after installing Arch Linux where you’ll find steps to install various other desktop environments and learn more about the OS. You can keep playing with it and see how powerful Arch is.
Let us know in the comments if you face any difficulty while installing Arch Linux.
KDE is a software project currently comprising a desktop environment known as Plasma, a collection of libraries and frameworks (KDE Frameworks) and several applications (KDE Applications) as well. KDE upstream has a well maintained UserBase wiki. Detailed information about most KDE applications can be found there.
Before installing Plasma, make sure you have a working Xorg installation on your system.
Install the plasma-meta meta-package or the plasma group. For differences between plasma-meta and plasma reference Package group. Alternatively, for a more minimal Plasma installation, install the plasma-desktop package.
To enable support for Wayland in Plasma, also install the plasma-wayland-session package.
To install the full set of KDE Applications, install the kde-applications group or the kde-applications-meta meta-package. Note that this will only install applications, it will not install any version of Plasma.
See Official repositories#kde-unstable
Plasma can be started either using a display manager, or from the console.
exec startkde
to your .xinitrc
file. If you want to start Xorg at login, please see Start X at login.XDG_SESSION_TYPE=wayland dbus-run-session startplasmacompositor
.[1]Most settings for KDE applications are stored in ~/.config/
. However, configuring KDE is primarily done through the System Settings application. It can be started from a terminal by executing systemsettings5
.
Plasma themes define the look of panels and plasmoids. For easy system-wide installation, some themes are available in both the official repositories and the AUR.
Plasma themes can also be installed through System Settings > Workspace Theme > Plasma Theme > Get new themes from the Internet.
The KDE-Store offers more Plasma customization's, like SDDM themes and splash-screens.
Breeze is not directly available for Qt4 since it cannot be built without KDE 4 packages, which have been dropped from the extra repository in August 2018 (FS#59784). However you can install breeze-gtk and pick GTK as GUI Style by running qtconfig-qt4
.
The recommended theme for a pleasant appearance in GTK applications is breeze-gtk or gnome-breeze-gitAUR, a GTK theme designed to mimic the appearance of Plasma's Breeze theme.Install kde-gtk-config (part of the plasma group) and select the installed GTK-theme for GTK2/GTK3-Theme in System Settings > Application Style > GNOME/GTK Application Style.
In some themes, tooltips in GTK applications have white text on white backgrounds making it difficult to read. To change the colors in GTK2 applications, find the section for tooltips in the .gtkrc-2.0
file and change it. For GTK3 application two files need to be changed, gtk.css
and settings.ini
.
Some GTK2 programs like vuescan-binAUR still look hardly usable due to invisible checkboxes with the Breeze or Adwaita skin in a Plasma session. To workaround this, install and select e.g. the Numix-Frost-Light skin of the numix-frost-themesAUR under System Settings > Application Style > GNOME/GTK Application Style > GTK2 Theme:. Numix-Frost-Light looks similar to Breeze.
User's face can be set through System Settings > Accounts Details > User Manager.
If User Manager is not found, install user-manager to get it.
Plasmoids are little scripted (plasmoid scripts) or coded (plasmoid binaries) KDE applications designed to enhance the functionality of your desktop.
The easiest way to install plasmoid scripts is by right-clicking onto a panel or the desktop and choosing Add Widgets > Get New Widgets.. > Download New Plasma Widgets. This will present a nice frontend for https://store.kde.org/ that allows you to install, uninstall, or update third-party plasmoid scripts with literally just one click.
Many Plasmoid binaries are available from the AUR.
Installplasma-pa or kmix (start Kmix from the Application Launcher). plasma-pa is now installed by default with plasma, no further configuration needed.
VolumePercentageStep=1
in the [Global]
section of ~/.config/kmixrc
.As the Plasma panel is on top of other windows, its shadow is drawn over them. [2] To disable this behaviour without impacting other shadows, installxorg-xprop and run:
then select the panel with the plus-sized cursor. [3] For automation, install xorg-xwininfo and create the following script:
Set execution permissions for the script:
The script can be run on login with Add Script in Autostart:
Window decorations can be changed in System Settings > Application Style > Window Decorations.
There you can also directly download and install more themes with one click, and some are available in the AUR.
Icon themes can be installed and changed on System Settings > Icons.
breeze
to the Inherits=
array in /usr/share/icon/theme-name/index.theme
, for example: Inherits=breeze,hicolor
. You need to reapply this patch after every update to the icon theme, consider using Pacman hooks to automate the process.The Plasma Netbook shell has been dropped from Plasma 5, see the following KDE forum post. However, you can achieve something similar by editing the file ~/.config/kwinrc
adding BorderlessMaximizedWindows=true
in the [Windows]
section.
To allow thumbnail generation for media or document files on the desktop and in Dolphin, install kdegraphics-thumbnailers and ffmpegthumbs.
Then enable the thumbnail categories for the desktop via right click on the desktop background > Configure Desktop > Icons > Configure Preview Plugins...
In Dolphin, navigate to Control > Configure Dolphin.. > General > Previews.
You can also configure printers in System Settings > Printers. To use this method, you must first install print-manager and cups. See CUPS#Configuration.
If you want to have access to Windows services, install Samba (package samba).
The Dolphin share functionality requires the package kdenetwork-filesharing and usershares, which the stock smb.conf
does not have enabled. Instructions to add them are in Samba#Enable Usershares, after which sharing in Dolphin should work out of the box after restarting Samba.
*
(asterisk) for both username and password when accessing a Windows share without authentication in Dolphin's prompt.Unlike GTK file browsers which utilize GVfs also for the launched program, opening files from Samba shares in Dolphin via KIO makes Plasma copy the whole file to the local system first with most programs (VLC is an exception).To workaround this, you can use a GTK based file browser like thunar with gvfs and gvfs-smb (and gnome-keyring for saving login credentials) to access SMB shares in a more able way.
Another possibility is to mount a Samba share via cifs-utils to make it look to Plasma like if the SMB share was just a normal local folder and thus can be accessed normally.See Samba#Manual mounting and Samba#Automatic mounting.
An GUI solution is available with samba-mounter-gitAUR, which offers basically the same functionality via an easy to use option located at System Settings > Network Drivers. However, it might break with new KDE Plasma versions.
KDE Desktop Activities are special workspaces where you can select specific settings for each activity that apply only when you are using said activity.
Installpowerdevil for an integrated Plasma power managing service. This service offers additional power saving features, monitor brightness control (if supported) and battery reporting including peripheral devices.
Yahoo messenger full version. An alternative package without NetworkManager and Bluez dependencies is provided by powerdevil-lightAUR.
The factual accuracy of this article or section is disputed.
Plasma can autostart applications and run scripts on startup and shutdown. To autostart an application, navigate to System Settings > Startup and Shutdown > Autostart and add the program or shell script of your choice. For applications, a .desktop file will be created, for shell scripts, a symlink will be created.

From Wikipedia:
Phonon is being widely used within KDE, for both audio (e.g., the System notifications or KDE audio apps) and video (e.g., the Dolphin video thumbnails).
You can choose between backends based on GStreamer and VLC – each available in versions for Qt4 applications and Qt5 applications (phonon-qt4-gstreamerAUR, phonon-qt5-gstreamer – phonon-qt4-vlcAUR, phonon-qt5-vlc).
Upstream prefers VLC but prominent Linux distributions (Kubuntu and Fedora-KDE for example) prefer GStreamer because that allows them to easily leave out patented MPEG codecs from the default installation. Both backends have a slightly different features set. The Gstreamer backend has some optional codec dependency, install them as needed:
In the past other backends were developed as well but are no longer maintained and their AUR packages have been deleted.
Note:The KDE project provides a suite of applications that integrate with the Plasma desktop. See the kde-applications group for a full listing of the available applications. Also see Category:KDE for related KDE application pages.
Aside from the programs provided in KDE Applications, there are many other applications available that can complement the Plasma desktop. Some of these are discussed below.
Navigate to the submenu System Settings > Input Devices > Keyboard > Advanced (tab) > 'Key Sequence to kill the X server' and ensure that the checkbox is ticked.
KCM stands for KConfig Module. KCMs can help you configure your system by providing interfaces in System Settings, or through the command line with kcmshell5.
More KCMs can be found at linux-apps.com.
KDE implements desktop search with a software called Baloo, a file indexing and searching solution.
The following web browsers can integrate with Plasma:
KDE offers its own stack for personal information management. This includes emails, contacts, calendar, etc. To install all the PIM packages, you could use the meta-package kdepim-meta.
Akonadi is a system meant to act as a local cache for PIM data, regardless of its origin, which can be then used by other applications. This includes the user's emails, contacts, calendars, events, journals, alarms, notes, and so on. Akonadi does not store any data by itself: the storage format depends on the nature of the data (for example, contacts may be stored in vCard format).
Install akonadi. For additional addons, install kdepim-addons.
Note: If you wish to use a database engine other than MariaDB, then when installing the akonadi package, use the following command to skip installing the mariadb dependencies:See also FS#32878.
By default Akonadi will use /usr/bin/mysqld
(MariaDB by default, see MySQL for alternative providers) to run a managed MySQL instance with the database stored in ~/.local/share/akonadi/db_data/
.
Akonadi supports using the system-wide MySQL for its database.[6]
This article or section needs expansion.
Akonadi supports either using the existing system-wide PostgreSQL instance, i.e. postgresql.service
, or running a PostgreSQL instance with user privileges and the database in ~/.local/share/akonadi/db_data/
.
Installpostgresql and postgresql-old-upgrade.
Edit Akonadi configuration file so that it has the following contents:
Note:[QPSQL]
section and set the appropriate variables in it.~/.local/share/akonadi/db_data/
.Start Akonadi with akonadictl start
, and check its status: akonadictl status
.
~/.local/share/akonadi/db_data/
will get automatically upgraded when a major PostgreSQL version upgrade is detected.This requires an already configured and running PostgreSQL.
Create a PostgreSQL user account for your user:
Create a database for Akonadi:
Configure Akonadi to use the system-wide PostgreSQL:
Port=
, User=
, Password=
in the [QPSQL]
section.Start Akonadi with akonadictl start
, and check its status: akonadictl status
.
To use SQLite edit Akonadi configuration file to match the configuration below:
Note:[QSQLITE3]
section and set the appropriate variables in it.~/.local/share/akonadi/akonadi.db
.See this section in the KDE userbase.
KDE Telepathy is a project with the goal to closely integrate Instant Messaging with the KDE desktop. It utilizes the Telepathy framework as a backend and is intended to replace Kopete.
To install all Telepathy protocols, install the telepathy group.To use the KDE Telepathy client, install the telepathy-kde-meta package that includes all the packages contained in the telepathy-kde group.
Telegram protocol is available using telepathy-haze, installing telegram-purpleAUR or telegram-purple-gitAUR and telepathy-morse-gitAUR. The username is the Telegram account telephone number (complete with the national prefix +xx
, e.g. +49
for Germany).
The configuration through the GUI may be tricky: if the phone number is not accepted when configuring a new account in the KDE Telepathy client (with an error message complaining about an invalid parameter which prevents the account creation), insert it between single quotes and then remove the quotes manually from the configuration file (~/.local/share/telepathy/mission-control/accounts.cfg
) after the account creation (if the quotes are not removed after, an authentication error should rise).
KDE Connect provides several features to connect your Android phone with your Linux desktop:
You will need to install KDE Connect both on your computer and on your Android. For PC side, installkdeconnect package. For Android side, install KDE Connect from Google Play or from F-Droid. If you want to browse your phone's filesystem, you need to installsshfs as well and configure filesystem exposes in your Android app.
It is possible to use KDE Connect even if you do not use the Plasma desktop. For desktop environments that use AppIndicators, such as Unity, install indicator-kdeconnectAUR package as well. For GNOME users, better integration can be achieved by installing gnome-shell-extension-gsconnectAUR instead of kdeconnect.
If you use a firewall, you need to open UDP and TCP ports 1714
through 1764
. See https://community.kde.org/KDEConnect#Troubleshooting.
The component chooser settings in Plasma does not allow changing the window manager anymore. [7]In order to change the window manager used you need to set the KDEWM
environment variable before KDE startup. [8] To do that you can create a script called set_window_manager.sh
in ~/.config/plasma-workspace/env/
and export the KDEWM
variable there. For example to use the i3 window manager :
And then make it executable :
The openbox package provides a session for using KDE with Openbox. To make use of this session, select KDE/Openbox from the display manager menu.
For those starting the session manually, add the following line to your xinit configuration:
When replacing Kwin with a window manager which does not provide a Compositor (such as Openbox), any desktop compositing effects e.g. transparency will be lost. In this case, install and run a separate Composite manager to provide the effects such as Xcompmgr or Compton.
To enable display resolution management and multiple monitors in Plasma, install kscreen. This provides additional options to System Settings > Display and Monitor.
To enable ICC profiles in Plasma, installcolord-kde. This provides additional options to System Settings > Color Corrections.
ICC profiles can be imported using Add Profile.
To disable this feature you currently can run the following command:
With Plasma Browser integration installed, KDE will show bookmarks in the application launcher.
To disable this feature you currently can run the following commands:
Try installing the ttf-dejavu and ttf-liberation packages.
After the installation, be sure to log out and back in. You should not have to modify anything in System Settings > Fonts. If you are using qt5ct, the settings in Qt5 Configuration Tool may override the font settings in System Settings.
If you have personally set up how your Fonts render, be aware that System Settings may alter their appearance. When you go System Settings > Fonts System Settings will likely alter your font configuration file (fonts.conf
).
There is no way to prevent this, but, if you set the values to match your fonts.conf
file, the expected font rendering will return (it will require you to restart your application or in a few cases restart your desktop). Note that Gnome's Font Preferences also does this.
Try to force font DPI to 96
in System Settings > Fonts.
If that does not work, try setting the DPI directly in your Xorg configuration as documented in Xorg#Setting DPI manually.
Many problems in KDE are related to its configuration.
Plasma problems are usually caused by unstable Plasma widgets (colloquially called plasmoids) or Plasma themes. First, find which was the last widget or theme you had installed and disable or uninstall it.
So, if your desktop suddenly exhibits 'locking up', this is likely caused by a faulty installed widget. If you cannot remember which widget you installed before the problem began (sometimes it can be an irregular problem), try to track it down by removing each widget until the problem ceases. Then you can uninstall the widget, and file a bug report on the KDE bug trackeronly if it is an official widget. If it is not, it is recommended to find the entry on the KDE Store and inform the developer of that widget about the problem (detailing steps to reproduce, etc.).
If you cannot find the problem, but you do not want all the settings to be lost, navigate to ~/.config/
and run the following command:
This command will rename all Plasma related configuration files to *.bak (e.g. plasmarc.bak
) of your user and when you will relogin into Plasma, you will have the default settings back. To undo that action, remove the .bak file extension. If you already have *.bak files, rename, move, or delete them first. It is highly recommended that you create regular backups anyway. See Synchronization and backup programs for a list of possible solutions.
The problem may be caused by old cache. Sometimes, after an upgrade, the old cache might introduce strange, hard to debug behaviour such as unkillable shells, hangs when changing various settings, Ark being unable to extract archives or Amarok not recognizing any of your music. This solution can also resolve problems with KDE and Qt applications looking bad after an update.
Rebuild the cache using the following commands:
Optionally, empty the ~/.cache/
folder contents, however, this will also clear the cache of other applications:
Hiding certain items in the System Tray settings (e.g. Audio Volume, Media Player or Notifications) also disables related features. Hiding the Audio Volume disables volume control keys, Media Player disables multimedia keys (rewind, stop, pause) and hiding Notifications disables showing notifications.
Make sure you have the proper driver for your GPU installed. See Xorg#Driver installation for more information. If you have an older card, it might help to #Disable desktop effects manually or automatically for defined applications or #Disable compositing.
This command prints out a summary of the current state of KWin including used options, used compositing backend and relevant OpenGL driver capabilities. See more on Martin's blog.
Plasma has desktop effects enabled by default and e.g. not every game will disable them automatically. You can disable desktop effects in System Settings > Desktop Behavior > Desktop Effects and you can toggle desktop effects with Alt+Shift+F12
.
Additionally, you can create custom KWin rules to automatically disable/enable compositing when a certain application/window starts under System Settings > Window Management > Window Rules.
If you use a transparent background without enabling the compositor, you will get the message:
In System Settings > Display and Monitor > Compositor, check Enable compositor on startup and restart Plasma.
In System Settings > Display and Monitor > Compositor, uncheck Enable compositor on startup and restart Plasma.
In System Settings > Display and Monitor > Compositor, uncheck Allow applications to block compositing. This may harm performance.
See NVIDIA/Troubleshooting#Avoid screen tearing in KDE (KWin).
Create the directory ~/.icons/default
and inside a file named index.theme
with the following contents:
Execute the following command:
Your local configuration settings for kscreen can override those set in xorg.conf
. Look for kscreen configuration files in ~/.local/share/kscreen/
and check if mode is being set to a resolution that is not supported by your monitor.
In order to add icons to tray, applications often make use of the library appindicator. If your icons are blurry, check which version of libappindicator you have installed. If you only have libappindicator-gtk2 installed, you can install libappindicator-gtk3 or libappindicator-sharp as an attempt to get clear icons.
If there is no sound after suspending and if KMix does not show audio devices which should be there, restarting plasmashell and pulseaudio may help:
Some applications may also need to be restarted in order for sound to play from them again.
This can be solved by installing the GStreamer libav plugin (package gst-libav). If you still encounter problems, you can try changing the Phonon backend used by installing another such as phonon-qt4-vlcAUR or phonon-qt5-vlc.
Then, make sure the backend is preferred via System Settings > Multimedia > Audio and Video > Backend.
If your system is able to suspend or hibernate using systemd but do not have these options shown in KDE, make sure powerdevil is installed.
First, make sure that KMail is not running. Then backup configuration:
Start System Settings > Online Accounts and remove all the resources. Go back to Dolphin and remove the original ~/.local/share/akonadi/
and ~/.config/akonadi/
- the copies you made ensure that you can back-track if necessary.
Now go back to the System Settings and carefully add the necessary resources. You should see the resource reading in your mail folders. Then start Kontact/KMail to see if it works properly.
For some IMAP accounts KMail will show the inbox as a top-level container (so it will not be possible to read messages there) with all other folders of this account inside.[9]. To solve this problem simply disable the server-side subscriptions in the KMail account settings.
While setting up EWS account in KMail, you may keep getting errors about failed authorization even for valid and fully working credentials. This is likely caused by broken communication between KWallet and KMail. To workaround the issue set a passsword via qdbus:
Using Fstab#Automount with systemd on a NFS volume may cause freezes, see bug report upstream.
See Qt#Disable/Change Qt journal logging behaviour.
See Qt#Configuration of Qt5 apps under environments other than KDE Plasma.
It is not recommended to turn off the KWallet password saving system in the user settings as it is required to save encrypted credentials like WiFi passphrases for each user. Persistently occuring KWallet dialogs can be the consequence of turning it off.
In case you find the dialogs to unlock the wallet annoying when applications want to access it, you can let the display managersSDDM and LightDM unlock the wallet at login automatically, see KDE Wallet#Unlock KDE Wallet automatically on login. The first wallet needs to be generated by KWallet (and not user-generated) in order to be usable for system program credentials.
In case you want the wallet credentials not to be opened in memory for every application, you can restrict applications from accessing it with kwalletmanager in the KWallet settings.
If you do not care for credential encryption at all, you can simply leave the password forms blank when KWallet asks for the password while creating a wallet. In this case, applications can access passwords without having to unlock the wallet first.
This can be solved by installing packagekit-qt5.
As described in KDE Bug 347772 NVIDIA OpenGL drivers and QML may not play well together with Qt 5. This may lead kscreenlocker_greet
to high CPU usage after unlocking the session. To work around this issue, set the QSG_RENDERER_LOOP
environment variable to basic
.
Then kill previous instances of the greeter with killall kscreenlocker_greet
.
If your home directory is on a ZFS pool, create a ~/.config/akonadi/mysql-local.conf
file with the following contents:
See MariaDB#OS error 22 when running on ZFS.
This is caused by the problematic way of GTK3 handling mouse scroll events. A workaround for this is to set environment variableGDK_CORE_DEVICE_EVENTS=1
. However, this workaround also breaks touchpad smooth scrolling and touchscreen scrolling.
When using TeamViewer, it may behave slowly if you use smooth animations (such as windows minimizing). See #Disable compositing as a workaround.
