Prepare the testing environment
Save the following script as /opt/kde/runPlasma5.sh
#!/bin/bash if [ -d /etc/X11/xinit/xinitrc.d ]; then for f in /etc/X11/xinit/xinitrc.d/*; do [ -x "$f" ] && . "$f" done unset f fi DISTRO=`source /etc/os-release 2>/dev/null; echo $ID_LIKE` export KF5=/opt/kde/install export QTDIR=/opt/qt5 # Change if you have your own qt build export PATH=$KF5/bin:$QTDIR/bin:$PATH export QT_PLUGIN_PATH=$KF5/lib/plugins:$KF5/lib64/plugins:$QTDIR/plugins:$QT_PLUGIN_PATH #On some distros, this is $KF5/lib64/qml:$QTDIR/qml or something similar. After the installation, choose the directory/directories which contains the "qt/qml" folder. export QML2_IMPORT_PATH=$KF5/lib/qml:$QTDIR/qml #Fixes for Debian's "look at me, I'm so important" setups if [ $DISTRO == "debian" ] then export QT_PLUGIN_PATH=$KF5/lib/`uname -m`-linux-gnu/plugins:$QTDIR/plugins export QML2_IMPORT_PATH=$KF5/lib/`uname -m`-linux-gnu/qml:$QTDIR/qml fi export QML_IMPORT_PATH=$QML2_IMPORT_PATH export XDG_DATA_DIRS=$KF5/share:/usr/share export XDG_CONFIG_DIRS=$KF5/etc/xdg:/etc/xdg # Uncomment to change default home paths #export XDG_DATA_HOME=$HOME/.kde5/local #export XDG_CONFIG_HOME=$HOME/.kde5/config #export XDG_CACHE_HOME=$HOME/.kde5/cache exec startkde
For what works on Debian Sid alongside with packaged KF5 nicely see: Using (parts of) self-built KF 5, Plasma 5 and/or KDE Applications on Debian
Because we installed Plasma 5 to a custom path, we need to make dbus aware of these new locations.
Create a file /etc/dbus-1/session-local.conf with the following contents:
<!DOCTYPE busconfig PUBLIC "-//freedesktop//DTD D-Bus Bus Configuration 1.0//EN" "http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd"> <busconfig> <servicedir>/opt/kde/install/share/dbus-1/services</servicedir> </busconfig>
Create another file /etc/dbus-1/system-local.conf with the following contents:
<!DOCTYPE busconfig PUBLIC "-//freedesktop//DTD D-Bus Bus Configuration 1.0//EN" "http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd"> <busconfig> <servicedir>/opt/kde/install/share/dbus-1/system-services</servicedir> <includedir>/opt/kde/install/etc/dbus-1/system.d</includedir> </busconfig>
Because dbus will load all these new paths each time you login, you should rename these files (to eg system-local.conf.bk and session-local.conf.bk) before starting your default Plasma 4 or other distro sessions.
Finally, there are several ways of running Plasma 5. Choose the one which suits you best.
Using a login manager
The recommended login manager is SDDM. But this method should work with any login manager.
sudo cp /opt/kde/runPlasma5.sh /usr/share/xsessions sudo chmod +x /usr/share/xsessions/runPlasma5.sh sudo cp /opt/kde/install/share/xsessions/plasma.desktop /usr/share/xsessions/plasmaGit.desktop
Edit /usr/share/xsessions/plasmaGit.desktop and change the paths as:
Exec=/usr/share/xsessions/runPlasma5.sh TryExec=/usr/share/xsessions/runPlasma5.sh Name=Plasma Git
After this logout of your current session, select Plasma Git in the options and login. You should now have the last Plasma 5 running.
This is what I found works on Debian Sid nicely. Put the script which sets up the environment into ~/.config/plasma-workspace/env, chmod +x it and be done. Aside from the "Using a login manager" approach probably – I didn´t test it –, this is the only thing that worked on Debian. Additionally to that it does not need any changes to system wide configuration files. This directory replaced ~/.kde/env from KDE SC 4 and older times.
Specifically none of the put it into some user wide or system wide shell profile files worked. Also putting it at start of /usr/bin/startkde worked, as environment still got reset to the default.
From the command line
- Edit your xinitrc file :
mv ~/.xinitrc ~/.xinitrc.bk # Backup any existing xinitrc file ln -s /opt/kde/runPlasma5.sh ~/.xinitrc
Log out of your current session, login to a tty (eg tty2 by pressing
Ctrl+Alt+F2) and run
startx. This should read your ~/.xinitrc and log you into a Plasma 5 desktop.
- Instead of editing your xinitrc, you can simply override it by running
Due to system security DBus activation on the system bus which can switch users as well as all polkit policy files are only read from /etc/
If you have a working system, generally this step is optional and only needed when working on those components
If installing to a non-default prefix you will need to: sudo ln -s /opt/kde5/etc/dbus-1/system.d/* /etc/dbus-1/system.d/. sudo ln -s /opt/kde5/etc/polkit-1/rules.d* /etc/polkit-1/rules.d.
