This also happens to me, using a Lenovo 3000 N200 (TY2BBGE), Intel GMA X3100 / GM965. I'm on the current Hardy beta, but the bug has also occured on Gutsy before I upgraded.
Running Compiz has not triggered this bug here (I use Compiz exclusively). Playing 3D games based on OpenGL reliably causes the symptoms described above after playing for some time, an hour at most. Note that I have not seen any funny colors, but the rest of the symptoms match my problem. Sometimes the screen flashing does not happen, but instead all graphical output seems to freeze. The system does not lock up, but it "does not respond to Ctrl+Alt+F1 or Ctrl+Alt+Backspace, but does reboot on Alt+SysRq+b" (as described above). This may be a seperate issue, I'm not sure. -- intel gm965 freezes with 3d applications https://bugs.launchpad.net/bugs/120834 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
