OK so not much is going on… Thought I might as well pass along some general knowledge.

Changing the resolution of a Linux console is a fairly simple task (and requires a reboot) and is generally a nice thing to do if you intend using the console a lot.

Start off by logging in as root, and open your Grub menu file (mine is in /boot/grub/menu.lst). Next, find the option that would normally boot your Linux system (probably looks something like the following):

kernel /vmlinuz-2.6.8-1-386 root=/dev/hda3 ro

Now, simply append to the end “vga=788”, so it ends up looking something like this:

kernel /vmlinuz-2.6.8-1-386 root=/dev/hda3 ro vga=788

The “788” is a code which tells the console to be 800x600 with a 16bit colour depth. Check out a table ot codes for all resolutions and colour depths by clicking the “read more” link below this post.

Save the file, reboot, and enjoy :-).

For reference, here are some VGA codes:

   Colors ( depth) 640x480 800x600 1024x768 1280x1024 1600x1200
   ---------------+-------+-------+--------+---------+---------
   256    ( 8 bit)| 769    771     773      775       796
   32,768 (15 bit)| 784    787     790      793       797
   65,536 (16 bit)| 785    788     791      794       798
   16.8M  (24 bit)| 786    789     792      795       799
