I have very similar problems but the video driver in use is xserver- xorg-video-intel . In addition to "Ubuntu running in low-graphics mode" error though all video is unusable--drop to command prompt, etc, produce a few colored pixels on the virtual terminals but that's all. Recovery mode boots are also unusable on this machine with the 2.6.31-15 kernel and 1:7.4+3ubuntu10 xserver-related packages installed.
The only reliably working configuration was to revert back to the 1:7.4+3ubuntu7 versions of all xserver packages and the 2.6.31-14 kernel. -- afte recent update which included xorg, xserver etc causes low-graphics mode error at start https://bugs.launchpad.net/bugs/491483 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
