To be honest I've never found out the difference between 3D accel and r128 DRI/3D. All I know is that the default debian/ubuntu xfree86 crashes in seconds flat if I run glxgears, although it may last much longer (over night or a little longer [seems somewhat unpredictable while running mundane desktop apps other than it will eventually lockup]) if glxgears is not run, and this doesn't happen with daenzer's xfree86 and the tweaks mentioned. I would like to note that I have tested the same XF86Config file with both xservers; This results in the freeze with the default xfree and not freezing with daenzer's xfree as stated above. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
