https://bugs.freedesktop.org/show_bug.cgi?id=35697 --- Comment #13 from Christophe Saout <christophe@xxxxxxxx> 2011-03-28 02:01:51 PDT --- This sounds an very similar to the issue I am having. Note that I am seeing this for quite a while now, ever since I switched to the gallium r300 driver. First I blamed it for most of my components being bleeding-edge (kernel drm, userspace libraries and so on). But the stuff slowly got merged into the kernel and distributions, but the issue persists. I had high hops for the page-flipping bug fix in 2.6.38, but it didn't fix the issue I am seeing. Most of the time, at some point X would just stop updating the screen (sound continues working and everything else seems to be alive). Actually, I traced it down to compiz being unable to update the screen. Ctrl-Alt-F1 to the console, "killall -9 compiz" and starting another non-GL window manager, the desktop is usable just fine. (in 80% of the cases, I also had occasional total lockups, where I had to hard reset the machine) Most of the time, this issue is triggered by heavy screen updates. I tend to not run Flash full-screen, but this is the kind of screen updates that is likely to trigger the issue. Sometimes I can go for 1 day without that type of crash, sometimes I can get it within 30 minutes. After killing compiz (when the issue got triggered), GL is totally unusable. Also, while the whole desktop then fully functional, a simple glxgears would just lock up, both via AIGLX or directly. Killing the X server resolves the issue, but sometimes even that won't help, everything GL related seems then to be totally locked up and only a reboot can resolve the issue. I am also running 64 bit Gentoo and only out-of-the box software versions (2.6.38, mesa-7.10.1) at the moment, and sane compiler flags (-O2 -march=core2) on a Lenovo T60 (Mobility X1400, r500 family). I haven't tried disabling page flipping or any patches yet, since I just stumbled upon this bug report. So, I'm not sure if this is the same or a different issue. It seems to be something in the kernel locking up, and in most of the cases userspace is still running, so there might be a chance to being able to debug it without resorting to guess-work. Since the thing starte since I switched to the gallium version, I wouldn't know how to start bisecting. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
