So this is not an option, at least not on the fly. Okay. In that case maybe try to start slow. Just boot without X and see how that goes. If that works well try to start X. >> Maybe it shows what is wrong. Information about the >> platform is probably usefull, too.

Your hardware configuration does look that unusual. If someone reading this could say that he is also using radeon driver, that would be nice. If your problems rise again once you do start X then someone should try to start debugging this. You could also wait for the next stable release hoping that the problems goes away. >Regards, >Ralf Sebasitan
