Package: xserver-xorg-video-intel

Version: 2:2.9.1-4

Severity: normal


I boot my laptop(CMPC) normally, then I attach an external monitor to the VGA port.

I use this command “xrandr --output LVDS1 --off --output VGA1 –-auto”, switch display to external display only mode.

Then I unplug VGA cable, the internal monitor still has no display.I can’t use it any more.Attach the external monitor again and switch back to internal display is the only recover way without restarting.


Please let me know if there's anything else I should try to help resolve this.




Attached is the most recent Xorg log file /var/log/Xorg.0.log.
Xrandr output:

Screen 0: minimum 320 x 200, current 1024 x 600, maximum 4096 x 4096

VGA1 disconnected (normal left inverted right x axis y axis)

LVDS1 connected 1024x600+0+0 (normal left inverted right x axis y axis) 222mm x 125mm

   1024x600       60.0*+

   800x600        60.3 

   640x480        59.9

Why don't you switch LVDS on again before unplugging your cable? That
would seem to be the same steps in reverse order (plug cable, disable
LVDS in one case; enable LVDS again, unplug cable in the other one).

Closing as, like Julien, that doesn't seem a bug to me.
