Public bug reported:
The system comes back after suspend, but when I use the open source
driver, I can only access other VTs, but not my X session. When I
switch to the proprietary driver, I also lose access to other VTs after
resume as well. Plugging in another monitor works as long as the system
is configured to use that monitor automatically. The screen can't be
made to wake up and won't wake even after hours of using the system.
I've also tried closing and opening the laptop lid, and doing other
things that would normally wake up the screen (disable display then
restore, etc.). I also tried following some directions I found online
suggesting adding acpi_osi=Linux to the boot cmdline, but that only
served to make the system crash when switching VTs (the X VT still came
up black with no backlight).
This worked under 12.04 just fine.
