If I excute xrandr -q a couple times in a row it sometimes displays a disabled VGA out but on the next invocation of xrandr it is disabled again: arjan@nebula:~$ xrandr Screen 0: minimum 320 x 200, current 1024 x 768, maximum 1280 x 1280 VGA connected (normal left inverted right) 1280x800 60.0 1280x768 60.0 1024x768 60.0 800x600 60.3 640x480 59.9 LVDS connected 1024x768+0+0 (normal left inverted right) 304mm x 228mm 1024x768 60.0*+ 800x600 60.3 640x480 59.9 arjan@nebula:~$ xrandr Screen 0: minimum 320 x 200, current 1024 x 768, maximum 1280 x 1280 VGA disconnected (normal left inverted right) LVDS connected 1024x768+0+0 (normal left inverted right) 304mm x 228mm 1024x768 60.0*+ 800x600 60.3 640x480 59.9 arjan@nebula:~$ xrandr Screen 0: minimum 320 x 200, current 1024 x 768, maximum 1280 x 1280 VGA connected (normal left inverted right) 1280x800 60.0 1280x768 60.0 1024x768 60.0 800x600 60.3 640x480 59.9 LVDS connected 1024x768+0+0 (normal left inverted right) 304mm x 228mm 1024x768 60.0*+ 800x600 60.3 640x480 59.9 Also XVideo is not working anymore (not sure of that is used in gnome-screensaver). Is this related to detecting of two displays? Totem, which uses XV, does not display anything. And the last time I runned totem after trying xrandr --output VGA --off it crashed Xorg. After I rebooted the machine and started totem again and did a xrandr --output VGA --off it crashed again. Greetings Arjan
