HELP !! I enabled desktop effects in OpenSuse 11 and the screen had gone black... How do I turn desktop effects off from the command line? How do I get to a command line? I tried rescue system and it booted to a prompt. Then I tried sax2 and gnome-xgl-switch commands but it didn't recognise either of them.

I also got rid of the task bar and have no idea how to get it back

I have an ATI card and I imagine that's the reason it crashed in the first place. I can sort that out later if I could just get the desktop back..
