Hi
I have installed ubuntu 9.10 and as soons as the display goes in standby or the laptop goes in suspend to ram/to disk my screen stays black. The laptop has an ATI mobility M6.

I assume that ubuntu comes with an open source driver and not with the one provided by ATI, correct? Should I install the native ATI driver, how is it called and do I have to uninstall s.th. in prior?
