It seems like the problem disappeared (or at least became quite rare) with linux-restricted-modules-2.6.24-18-rt, but now that I upgraded to linux-restricted-modules-2.6.24-19-rt, it is frequent again (2/3 or 3/4 startups), hence becoming quite annoying.
The symptoms have quite changed : once I switched to metacity, glxgears (which previously would not run at all) hangs for 5 to 60 seconds, then seems to run normally. GL based screen savers, however, run very slowly (say, 0.05 FPS...). However I still have the same error messages in Xorg.0.log -- Intermittent problem with GL applications in linux-rt https://bugs.launchpad.net/bugs/236998 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
