Hi narr, Thanks for adding the information. Nothing jumps out at me in the logs as problematic, although there's a few warnings which could be clues:

Thanks for reporting that you crashed the system with glxinfo - that's exactly the right thing to do here. It's useful data that crashing it didn't result in messages to Xorg.0.log. I see a few similar bugs in via/3d behavior upstream in Xorg's bug tracker, but not sure if any of them are matches: https://bugs.freedesktop.org/show_bug.cgi?id=1280 https://bugs.freedesktop.org/show_bug.cgi?id=9080 https://bugs.freedesktop.org/show_bug.cgi?id=10499 Can you try running glxgears and see if it too crashes the system, or produces any error messages mentioned on these bugs? Also, after X has frozen, what steps do you take to recover? Do you do ctrl-alt-bkspace to restart it, or reboot the computer, or something else? Also, have you ever collected a backtrace before? I think if you do not find a match yourself, our next step would be to get a backtrace of glxinfo. I can give you a sequence of commands to run if you've not done this before, and would like to try this route. -- Freezes with VIA KM400/VT8378 (regression) https://bugs.launchpad.net/bugs/118163 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
