Plasma is the desktop environment from KDE, a software project comprising of a collection of libraries known as KDE Frameworks, and several applications known as KDE Applications. Their UserBase wiki has detailed information about most KDE Applications.
ppc64le
, s390x
, armhf
, or riscv64
architectures due to the kdeplasma-addons dependency not being available there. However, the rest of Plasma may be installed separately to potentially get a functional desktop.
- Create a non-privileged user account for security reasons, if you skipped this step during Installation.
- Enable community repository. Setup-desktop script automatically does this for you.
- Install graphics driver for your video hardware.
Installation using setup-desktop
The Alpine Linux script for setting up a desktop quickly is setup-desktop.
# setup-desktop
On running the above command, you will be prompted to select a desktop environment.
Which desktop environment? ('gnome', 'plasma', 'xfce', 'mate', 'sway' or 'none') [none]
Once you have chosen a desktop environment, this script installs the chosen desktop along with all the necessary packages, firefox browser and adds the necessary services to run on startup. You can reboot when complete and the system will boot into a graphical login screen with the desktop environment. Depending on the desktop chosen, the script also activates the necessary services like dbus, elogind, login manager etc..
To view all the packages that are installed by the script for the chosen desktop you can issue the below command:
# cat /sbin/setup-desktop
When Plasma is chosen, the above utility also installs Pipewire for audio and SDDM as display manager.
Manual Installation
Prerequisites
- For users interested in Xorg as opposed to Wayland, install the Xorg base packages
- Install and configure D-Bus
- Install and configure Elogind
- Wayland users: Install package xf86-input-libinput
The following command will install the Plasma desktop as specified by the plasma metapackage, including the sddm display manager and other assorted niceties.
# apk add plasma-desktop-meta
Setting up eudev on a desktop system is recommended:
# setup-devd udev
For more details and advanced instructions see Device Manager.
KDE Applications
To install the full set of KDE Applications, install kde-applications. You can also choose to install a smaller set of applications by installing any of the subpackages:
ppc64le
or s390x
.- kde-applications-accessibility
- kde-applications-admin
- kde-applications-base
- kde-applications-edu
- kde-applications-games
- kde-applications-graphics
- kde-applications-multimedia
- kde-applications-network
- kde-applications-pim
- kde-applications-sdk
- kde-applications-utils
- kde-applications-webdev
Starting Plasma
Plasma can be started using a display manager or from the console.
Using a display manager
When Plasma is installed via the plasma meta-package, the display manager is set up using sddm.
Make sure you enable and start the SDDM service.
rc-update add sddm rc-service sddm start
- Select Plasma to launch a new session in Wayland
- Select Plasma (X11) to launch a new session in Xorg
From the console
The Xorg session can be launched by installing xinit and appending exec startplasma-x11
to your .xinitrc
file. To start X:
xinit
For the Wayland session run
XDG_SESSION_TYPE=wayland dbus-run-session startplasma-wayland
Troubleshooting
HiDPI Scaling
When using high resolution screens, e.g. 4K, you might need to apply scaling so the fonts and windows are not too small.
In order to achieve this you can open Settings -> Display and Monitor
and change the slider under Global Scale to an appropriate value.
You can also change the mouse cursor and icon size under Settings -> Appearance
.
If your taskbar and window decorations are still too small, you might want to create the file ~/.xprofile to define the PLASMA_USE_QT_SCALING environment variable:
export PLASMA_USE_QT_SCALING=1
After creating this file, you may need to restart your session to apply this modification.
