Public bug reported:
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.
