Public bug reported:
I'm running Gnome Shell under Oneiric. All updates applied as of 31st
Jan 2012. I run on a Lenovo Thinkpad x201, which I dock into a Lenovo
x200 ultrabase docking station. Attached to the ultrabase (by VGA) is an
iiyama Full HD LCD monitor.
My standard mode of operation is to use the laptop docked, with the lid
closed and the output directed to the external monitor only. When I am
away from my base, I undock and run on the internal LCD panel only.
Either mode works OK, but changing between the two seems to cause lots
of problems, especially the undock operation.
By itself, when undocking, Oneric usually leaves me with the internal
LCD panel blank. Once in this state, using Fn-F7 (the Thinkpad "switch
monitor" key) doesn't help. A reboot is usually required to recover. I
have been able to improve matters by using xrandr to manually move over
to the internal LCD panel before undocking. This usually works (though
not always), but often results in a pop-up panel with a lot of error
messages, as follows:
