Bug Description
Hello,
I've installed Ubuntu 5.10 on a Dell Inspiron 8000 laptop (with an ATI Mobility
M4, 8mb video ram). When I try to use 1280x1024, depth 16bpp, either a) the
system will hang completely when X.org starts (or if I run via startx),
producing a "bleeding pixel" effect on the LCD screen and completely locking the
machine, or b) X.org will start normally, but running glxinfo, glxgears etc.
causes a segmentation fault. I suspect this is a problem with DRI. I will attach
my xorg.conf and Xorg.0.log, and as you can see it reports that acceleration is
enabled - however, any application that takes advantage of acceleration crashes.
Under 1024x768, 16bpp, DRI accelleration works perfectly and there are no
"bleeding pixel" lockups, and under 1400x1050, 16bpp resolution, DRI is disabled
("static buffer allocation failed - need at least 8663 kB video memory") but
glxgears etc. can run without segmentation faults.
