Title:
After suspend / resume only one monitor of dual head usable
Status in linux package in Ubuntu:
Incomplete
Bug description:
Using unity-2d on Precise, with dual head system, after suspend/resume
I find about 50% of the time that only the external monitor is
enabled. The mouse will only move on that display and the launcher is
shown on that display when before suspend it was on the laptop
display. Furthermore I cannot re-enable the laptop display using
System Settings > Displays (the laptop shows as Off, and if I enable
it it shows On but does not in fact come on). I have to reboot in
order to re-activate it.
Further analysis added 20 Mar 12 as described in comment #7
In System Settings > Power I have Do Nothing as the action on lid close (as
there is a problem with this Toshiba Satellite laptop if the lid is used to
suspend). I am suspending using the top panel menu action.
If I close the lid then I find that it turns off the laptop display and the
PC switches to single monitor mode on the external monitor, which is ok. On
opening the lid it reverts to dual monitor mode.
The bug described here is triggered if I initiate the suspend but then close
the lid before the suspend is complete. On re-opening the lid the PC resumes
but the laptop display does not switch back on.
