[SOLVED] grub wrong resolution

stripe · 10-02-2012, 03:54 PM

Hi all

still trying to find a linux distro that works for me (dual booting)

the problem is that with certain distros, the grub menu is "out of range" for my monitor even though the distro works fine.

how would I change the resolution of the grub screen so that it will show and be usable on my 19" monitor

cheers

Try grub-customizer if you want a GUI-based convenient tool. Get it from here: https://launchpad.net/grub-customizer

If using GRUB2, here's a cool FAQ : http://www.dedoimedo.com/computers/grub-2.html

Have you tried BURG? It's a good and new bootloader.

I imagine you are using grub2. If so, then looking inside my /etc/default/grub file, I see this...

Quote:

# 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=1024x600

There are two ways to list your VBE supported modes. The first way is at the grub command line. So during startup, press "c" at the grub screen. Then at the grub command line, type

Code:

set pager=1
vbeinfo

Or alternatively, if you have the hwinfo package installed, then you can list your VBE supported modes at the normal terminal command line with

Code:

sudo hwinfo --framebuffer

Then finally, using one of the VBE supported modes, modify your /etc/default/grub file similar to the above. And then lastly, type in "sudo update-grub" or similar, to rebuild your grub configuration.

Happy with ur solution... then tick "yes" and mark as Solved!
