Title:
Xorg/nouveau crashes when switching notebook monitor back on
Status in “xserver-xorg-video-nouveau” package in Ubuntu:
Expired
Bug description:
A colleague and me are using Ubuntu 12.04 on Lenovo T410 systems
[Nvidia NVS 3100M] in combination with a docking station and an
external monitor and noticed following bug:
Using the graphical tool for switching monitors: if you disable the
internal notebook monitor, only using the external one, everything
works fine (internal monitor is black). However, when you now try to
reenable the internal monitor again (so having an extended desktop
with both monitors), the external monitor goes black and both screens
stay off. Looking at Xorg.0.log via SSH shows that some part of Xorg
or the nouveau driver crashed.
This happens both in 32 bit and 64 bit version of 12.04 and both in a
fully updated system as well as when started as live system from USB
stick.
One way to prevent this from happening is to use xrandr --auto, then
both monitors are in clone mode and you can use the graphical tool
again for setting up your desired configuration.
