Geoff Teale (tealeg) wrote : Lenovo E525 screen black on resume

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.

My setup is a Lenovo Thinkpad E525, AMD A8-3500m.
