Screen goes dark on resume from suspend

I have some problems with my video driver and suspend to ram. When I try to resume after suspend, my screen goes blank (dark). I tried restarting X, but nothing seems to happen. (The computer does still work when the screen is dark, i can ssh into it.)

The computer has an ATI radeon 9600 mobile graphics card, and it's using the open source "radeon" driver.

Im pretty shure this is a graphics driver iusse, because suspend works somewhat with the catalyst driver. (With catalyst suspend works once then crashes when i try to suspend a second time).

I have read the wiki entry for ATI-cards but it doesn't say anything about using suspend with the "radeon"-driver.

My xorg.conf

I don't know the specific answer to your question, but if you search the forums you're likely to find about a hundred threads that discuss the variations of this very problem.

I find the following very useful:

If you are using pm-suspend, answer the survey and try the quirks proposed there.
