--- Comment #10 from Nicos Gollan <[email protected]> 2010-04-18 07:23:32 PDT --- (In reply to comment #0) > Using a Radeon HD 4650 with a LG W3000H screen, with either git drivers or the > ones that come with the ubuntu lucid beta, results in a black screen on boot. I'm getting something similar, and I have something for you to try: Start the system with UMS (i.e., the radeon.modeset=0 kernel parameter). When you are on the login screen, switch to a console, kill the desktop manager, and unload the "radeon" module. Once you unloaded it successfully, try manually loading it with the "modeset=1" parameter. If you get a high-res console then, start the desktop manager, and you should be fine. Fun thing is, that usually works for me, I get working KMS even on a dual-monitor setup on a Radeon HD4350 and an HD4870 that way, on the 4350 it will run stable for several weeks with an OpenGL accelerated KDE desktop without even showing graphical glitches. However, if I start without the modeset=0 parameter, my system will come up with a black screen once the module is (auto)loaded, and eventually freeze. I tried debugging via serial console, but nothing unusual came up. Running a 2.6.33 kernel from Debian experimental repository, as well as radeon X drivers from there (currently 6.13.0). -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ xorg-driver-ati mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-driver-ati
