Plugging in the VGA connector in parallel to the already plugged in DVI-D conenctor after wakeup from s2ram helps as a work around. In this case then the external monitor shows again the KDE desktop. After few seconds I can then plug off the VGA connector from the docking station and can continue with my work. -- Toralf, pgp key: 872AE508 0076E94E _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
