Aha ... fixed it. Updated my motherboard BIOS. Now its rock solid on on ubuntu 8.10. Can't test 9.04 just now.
The board is an ASUS M3A78-EM. Old (bad) bios was 1206. New (good) bios = 1602 That update skips a few intermediate levels, so I have no idea which one actually fixed it. -- ati driver 2.6 kernel timings 2d desktop random horizontial flicker https://bugs.launchpad.net/bugs/355262 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
