I can confirm, too. The driver from Debian seems to work as a workaround (no problems after two days of using the computer, watching the Youtube, using media players with xv output etc.).
By the way: did you get the bulletproof X- warning about Ubuntu being in low graphics mode, and an offer to troubleshoot X? I didn't: the gdm just tried to start, then showed a black screen, and the computer restarted after a few minutes. No warnings, no offers. -- [Jaunty] X won't start on Voodoo 3 (rev 01) after upgrade to jaunty https://bugs.launchpad.net/bugs/371432 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
