NO DISPLAY WITH UBUNTU ON AN OLD PC

When installing UBUNTU Server on an old PC i encountered display problems. The machine would run the server bit nothing showed up on the display. As the display card was an old VGA thing I had to modify the GRUB config.
I found this bug report after a lengthy Google search – basically the GRUB boot loader was using a resolution my graphics card couldn’t handle (something ridiculous like 640 x 480).

All I had to do was edit a grub config file, like so:

sudo nano /etc/default/grub

And change a line that says:

#GRUB_GFXMODE=640x480

to

GRUB_GFXMODE=800x600    or whatever your card can handle.

Notice I also removed the hash so it is no longer a comment.

Once this was done, I told grub to rebuild it’s runtime configuration files form the config file I had provided, like so:

update-grub

After that command completed, I restarted, and now the console is working normally.
