Hallo all,
i get this error if try to use external monitor with my laptop (Asus
zenbook ux31e). Usually it is configured automatically or with gui. But
not it is not working. I got this regression for some weeks after some
of updates. I assume it was one of xorg/intel driver updates. I use
ubuntu 12.04,
I tested:
- kernel versions 3.2.0-12-generic, 3.2.0-17-generic and vanilla git
3.3.0-rc6-00164-g4f262ac.
- X.Org X Server 1.12.0
- xserver-xorg-video-intel i tested default precise version
2:2.17.0-1ubuntu4 and xorg-edgers version
2:2.18.0+git20120308.aa7a2bd7-0ubuntu0sarvatt
without any luck :(
suddenly i can't get old working version to "bisect" it.
if i run this command:
xrandr --output eDP1 --auto --output VGA1 --auto --same-as eDP1
i get:
xrandr: cannot find crtc for output eDP1
here is output of xrandr:
