Comment 18 for bug 816035

Maybe this kernel setting should be enabled by default in Ubuntu Linux as well. For GRUB the problem still exists, but can be worked around by re-installing GRUB with setting "GRUB_TERMINAL=console" (in /etc/default/grub). This puts GRUB into simple text mode which (in my case at least) does not cause any problems.

Thanks to apw for analyzing this and offering a solution!
