Now the boot process was OK using the laptop internal display.. gdm and X showed up on the internal display OK. When I was in X I connected the DVI cable to the dock, and went to gnome Monitors application. Same thing - the external display is shown as two separate devices. Although they don't work - no matter which one of the external displays I choose I don't get picture on the external DVI display. I also tried with xrandr: $ xrandr Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 8192 x 8192 VGA-0 disconnected (normal left inverted right x axis y axis) LVDS connected 1680x1050+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1680x1050 60.0*+ 1400x1050 60.0 60.0 1280x1024 59.9 60.0 1440x900 59.9 1280x960 60.0 59.9 1280x854 59.9 1280x800 59.8 1280x720 59.9 1152x768 59.8 1024x768 60.0 59.9 800x600 60.3 59.9 56.2 848x480 59.7 720x480 59.7 640x480 59.9 59.4 DVI-0 connected (normal left inverted right x axis y axis) 1920x1080 59.9 + 1600x1200 60.0 1680x1050 60.0 1280x1024 60.0 1440x900 59.9 1280x960 60.0 1280x800 59.8 1024x768 60.0 800x600 60.3 56.2 640x480 60.0 HDMI-0 connected (normal left inverted right x axis y axis) 1920x1080 59.9 + 1600x1200 60.0 1680x1050 60.0 1280x1024 60.0 1440x900 59.9 1280x960 60.0 1280x800 59.8 1024x768 60.0 800x600 60.3 56.2 640x480 60.0 $ xrandr --output DVI-0 --right-of LVDS Didn't make a difference.. no picture on the external DVI display. I wonder if that HDMI-0 is the key to the problem.. I don't have anything connected to the HDMI connector on the laptop. There's no HDMI connector on the dock, it's only in the laptop. -- Pasi _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
