[Bug 1034002] Re: 1002:9641 [Lenovo ThinkPad E525] Screen black on resume
** Summary changed:
- 1002:9641 1002:9641 [Lenovo ThinkPad E525] Screen black on resume
+ 1002:9641 [Lenovo ThinkPad E525] Screen black on resume
** Description changed:
I did the kernel smoke test for the quantal kernel on precise.
I can suspend and resume however when I resume I the screen stays black.
It looks like the backlight isn't coming on, but it's noteable that I
- don't see anything on my external screen either. I can see consoles
- on my external monitor (over HDMI) and if I disconnect the HDMI cable
- and reconnect it then I am also able to see my Unity session on that
- screen.

This issue is present with both the quantal kernel and the stock 12.04
one.
- My setup is a Lenovo Thinkpad E525, AMD A8-3500m.
