To install the nvidia driver I used emerge by setting the video card in /etc/make.conf to nvidia and running emerge -avDN world.
startx works fine but starting kde doesn't. It auto logs in, a wallpaper and mouse appear, but plasma-desktop won't start. Starting plasma-desktop manually gives me either:
Code:
Cannot find the D-Bus session server: "Unable to autolaunch a dbus-daemon without a $DISPLAY for X11"
or
Code:
Invalid D-BUS interface name "org.kde.plasma-desktop.PlasmaApp"
