Bug Description

The following entry in /boot/grub/menu.lst resulted in a beautiful highres console with Debian Etch. With Ubuntu it makes console switching impossible because Ctrl+Alt+F1 etc. results in a messed up screen content. Fortunately Ctrl+Alt+F7 brings back the GUI.

## additional options to use with the default boot option, but not with the
## alternatives
## e.g. defoptions=vga=791 resume=/dev/hda5
# defoptions=vga=791 quiet splash

Adding vga=791 leads to the problem. Screenshot will follow.

Maybe http://www.thinkwiki.org/wiki/S3_SuperSavage_IX/C is of interest.

Hello,
can you try the fix proposed in bug 129910 fixes the issue ? (basically, add fbcon to /etc/initramfs-tools/modules, run sudo update-initramfs -u, and reboot with vga=whatever). I think your issue might be caused by that bug
