How can I increase the console resolution of my Ubuntu server

Solution 1:

Try appending vga=791 to the linux (kernel) line (in /etc/default/grub).

See console Framebuffer for additional resolutions (if you want to lower it further).

Solution 2:

I used two parameters in /etc/default/grub:

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
GRUB_GFXMODE=1366x768x24
# bug workaround
GRUB_GFXPAYLOAD_LINUX=keep

I found the second item by reading the shell scripts in /etc/grub.d.

Be sure to "set pager=1" before running vbeinfo so you can read the output.

Be sure to run "sudo update-grub" when you are done
