Thanks Fabian! But we use the displaymanager KDM and i can't find the right location to configure this. I tried to configure in /etc/X11/xorg.conf : Section "ServerFlags" Option "AllowIndirectGLX" "on" or "True" and Option "AllowIndirectGLXProtocol" "on" or "True" EndSection in /etc/X11/xdm/Xservers : :0 local /usr/bin/X -nolisten tcp +iglx -br vt7 in /usr/share/kde4/config/kgm/kdmrc : ServerArgsLocal=-nolisten tcp +iglx But nothing had the effect that the option "+iglx" is adoptd to the commandline.
