After upgrading my server (that isn’t running X) to Ubuntu 9.10 (Karmic Koala), I found that the console on my LCD monitor was cropping out several characters from the left and right sides. It wasn’t hard to fix, though, given the magick incantations:
If you upgraded to Karmic
You’ll have grub 1 (legacy). To fix it, follow this thread, and edit /boot/grub/menu.lst. Look for the line that starts with “defoptions” — uncomment the line and add “vga=791″ (or 789 for lower resolution):
## additional options to use with the default boot option, but not with the ## alternatives ## e.g. defoptions=vga=791 resume=/dev/hda5 # defoptions=quiet splash defoptions=vga=791
Save the file and then reboot.
If you installed Karmic directly
You’ll be running grub 2, which requires these instructions. I’ve reformatted them here for posterity:
Step one: In /etc/default/grub, add this line:
set gfxmode=1024x768
Step two: In /etc/grub.d/00_header, add the highlighted line:
[bash highlight="3"]
if loadfont `make_system_path_relative_to_its_root ${GRUB_FONT_PATH}` ; then
set gfxmode=${GRUB_GFXMODE}
set gfxpayload=keep
insmod gfxterm
[/bash]
Step three: Run update-grub, and reboot.
