/etc/default/grub references vbeinfo

Asked by scoopex on 2012-12-22

I would like to set the graphics of grub - the configuration file /etc/default/grub references vbeinfo but this tools does not seem to be part of ubuntu anymore.
(according to packages.ubuntu.com)

# 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'

Please update the reference of vbeinfo to a existing tool....

Sorry, i oversight the fact that "vbeinfo" needs to be inserted at the grub prompt.

I added "1600x900" because this was show in the output of "vbeinfo", but it has no effect.

What needs to be used to change the graphics mode? (The hexcode?)

From boot menu switch to Grub prompt with [c]-key: grub>_
With [Esc] back to boot menu.

Resolution has to be supported from Grub and graphics card.

Write down the listing from Grub with

and graphics card (via terminal)
sudo hwinfo --framebuffer

Select a resolution both support, open /etc/default/grub, uncomment

sudo update grub
sudo reboot

Always make a backup before edit of system files.
