I have the same issue with nvidia kernel but nouveau works fine. Only an Alt-Sysrq-B gets any response even in recovery mode for 2.6.35-14-generic kernel.
Fortunately, I still had a mainline kernel (2.6.34-020634-generic) from testing before I upgraded to Maverick from Lucid. This kernel in recovery mode allowed me to get back in to set nouveau as the driver. I reported this in the duplicate bug https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/616626 -- nVidia card : X won't start since 1.9 update, no screens found https://bugs.launchpad.net/bugs/616023 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
