Black screen on startup or resume (only sometimes)

[Toby Webb]

I'm not sure this is an xorg bug or kernel driver / other.

Sometimes, when I resume the computer from a suspend, the screen stays black. Very black. It's now just happened on turning on the computer as well. This happens about once out of every 4 or 5 times (as far as I remember).

I am using: Ubuntu 12.04 32-bit

(Sometimes, the computer crashes when resuming also, but I'll file a different bug once that happens next time, as I think it's a different issue.)

I can get round this by switching to a terminal and switching back (ctrl-alt-f1 then ctrl-alt-f7), but it's still rather annoying.

I have tried searching for a solution to this, and have found similar problems, but mostly related to nVidia graphics cards and/or old Ubuntu versions, which is not my case.

Is there any debugging information I can send to help fix this bug?

Thanks
