Do this at your own risk as I will not be responsible for any issues:

One of the biggest complaints I get is the text screen is too small. I generally agree. More recent computers actually have the ability to use a higher resolution, but do not take advantage of it in the default mode. This instructable is for more advanced users. Please get help before starting this project if you are at least the little bit unsure.

You will need to have the documentation for both your video card and for your monitor. You will see numbers like 640x48 800x600 1024x768. Take those numbers and use the lower of the two from the video card and the monitor settings. If you can only use 640x400 then stop here. The 640x400 is the default. there is a 320x200, but I have not see that in years,

In my case the highest resolution for the monitor was 800x600. Still a boost over the default 640x400 screen.

Lastly you need to find out what your Linux system uses to boot, Lilo (we will not cover it), Grub (aka Grub1) or Grub 2.

For our purposes we will be using Grub2 for the images. Pictures in this step are the original screen shots.

Step 1: Grub (aka Grub1)

This is the easiest setup. as you only have to edit one file and then reboot.

$ sudo vim /boot/grub/menu.lst

or if you do not have vim

$ sudo nano  /boot/grub/menu.lst'


# (0) Arch Linux
title  Arch Linux
root   (hd2,2)
kernel /boot/vmlinuz26 root=/dev/disk/by-uuid/1069fde9-8696-49a8-bbec-b8f35458f4d9 ro
initrd /boot/kernel26.img


We need to choose the number for our monitor and graphics card. we need to look at the table to get a number that linux understands. We are just going to use the 256 line as colors are not critical for our test setup. In our case it is 800x600, so we would use 0x303.

  640x480 800x600 1024x768 1280x1024
256 0x301 0x303 0x305 0x307
32k 0x310 0x313 0x316 0x319
64k 0x311 0x314 0x317 0x31A
16M 0x312 0x315 0x318 0x31B

You will need to translate the hex umbers to decimal. Using a search engine can convert it for you. We need to append vga=771 to the kernel line.

initrd /boot/kernel26.img

Check you woirk. Some times it might be a good idea to copy the original lines, so in case the numbers do not work you can always still get into the system.

Check your work, save your work, and reboot. You should not ge able to do the new resolution.

Thanks for your Screen shots and Information about this...
Your welcome. Wish the shots could have been better though.
Thanks for sharing this, it really helped. We have been looking for nice <a href="http://www.gogambino.com" rel="nofollow">homes for sale Rockford, il</a>. We will definitely try this out.

Thanks for this great photo. I am wanting to go to a <a href="http://www.realestateonlinelearning.com/" rel="nofollow">Utah real estate school</a>. Do you know of any that I could go to? Thanks.
