I had the same problem (screen corruption, failure to get into desktop, Xorg crash, noveau idle channel messages), booting off the latest Xubuntu 12.10 amd64 liveusb on my ThinkPad W510 with NVidia GT216 (Quadro FX 880M) graphics. Once in a while I'd make it through bootup into xfce, but mostly not. Sometimes switching to a TTY and typing "startx" would work, but usually not. Booting with "nomodeset" seemed to fix the problem, but then once I got into the desktop, the resolution was too low (1024x768). Perhaps that's not surprising.
Next, I did an update from the repos. Updates included a bunch of Xorg and nouveau stuff, and at the same time I enabled the latest NVidia blob. Now I don't have this problem anymore. Not sure if it was the updates or the switch to the nvidia blob that fixed this liveusb. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1043518 Title: live cd is unusable due to video degradation To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1043518/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
