KDE, along with other desktop environments, include a special command in order to start graphical programs with root privileges. For KDE the command is. It can be used in the following manner:

Finally, KDM could fail due to errors in xorg.conf. Take a look in the and  logs and fix  accordingly. For additional help, reach out to the Gentoo KDE team on IRC at on Freenode.

The battery applet or solid notifications don't show the relevant info
