I can confirm it's a regression in 2.6.32. Kernel 2.6.31 works well (tested with 2.6.31.12). I hit this bug when I boot into single mode (recovery mode). Text cursor in top left corner appears instead of recovery menu. Combination "(CTRL) + Alt + Fx" doesn't work, I have to restart using Ctrl + Alt + Delete. I have no issue in non-single mode. X Windows start and Gnome works well.
I can fix it by parameter radeon.modeset=0 on kernel command line: ----------- kernel /vmlinuz-2.6.32-16-generic root=UUID=5564d628-8fc2-42b9-ba8d-cb1b7937a3e8 ro radeon.modeset=0 single Used SW: Ubuntu 10.04, amd64 kernel 2.6.32-16-generic xserver-xorg-video-radeon: 1:6.12.191-1ubuntu2 -- VIA KM400: Black screen after boot, no text console possible https://bugs.launchpad.net/bugs/518623 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
