= Configure dbus =
 
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:
 
<pre>
 
<!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>
 
</pre>
 
 
 
Create another file /etc/dbus-1/system-local.conf with the following contents:
 
<pre>
 
<!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>
 
</pre>
 
 
 
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.
 
 
 
= Running Plasma =
 
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.
 
<syntaxhighlight lang="bash">
 
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
 
</syntaxhighlight>
 
Edit /usr/share/xsessions/plasmaGit.desktop and change the paths as:
 
<pre>
 
Exec=/usr/share/xsessions/runPlasma5.sh
 
TryExec=/usr/share/xsessions/runPlasma5.sh
 
Name=Plasma Git
 
</pre>
 
After this logout of your current session, select Plasma Git in the options and login. You should now have the last Plasma 5 running.
 
 
 
== Using ~/.config/plasma-workspace/env ==
 
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:
 
<syntaxhighlight lang="bash">
 
mv ~/.xinitrc ~/.xinitrc.bk                # Backup any existing xinitrc file
 
ln -s /opt/kde/runPlasma5.sh ~/.xinitrc
 
</syntaxhighlight>
 
Log out of your current session, login to a tty (eg tty2 by pressing <code>Ctrl+Alt+F2</code>) and run <code>startx</code>. This should read your ~/.xinitrc and log you into a Plasma 5 desktop.
