I'm not sure if it's supposed to be that way or if it's a bug, but I'm forced to watch my Grub menu screen sloooooowly build itself. I have to watch it draw the lines around the menu like it was a C64 doing graphics and stuff. Takes about 5sec until I can finally see the menu entries and select one.

Any idea of how to get rid of that? I'm running Ubuntu Gnome 16.04, if it matters.

  • You probably have a Hi-Res screen. It is a challenge for Grub. ;)

I solved this by doing the following:

enter sudo gedit /etc/default/grub in terminal and edit/uncomment the line "GRUB_GFXMODE" so that it's GRUB_GFXMODE=640x480

    Thanks. It's still not instant, but much faster. I set it to 800x600 though. I also had to run update-grub2.

    You can see the possible resolutions for your computer at bootup: type c for command mode, then vbeinfo.

  • Rendering the menu at the native resolution took about 4 seconds. After setting GRUB_GFXMODE=1024x768x8 the menu is rendered instantly. The last number indicates color depth (in bits).

I uncommented the following line via sudo vi /etc/default/grub:

GRUB_TERMINAL_OUTPUT=console

According to the comment before it, this line disables graphical terminal.

Then I rebuilt the grub configuration, by doing this (on arch):

sudo grub-mkconfig -o /boot/grub/grub.cfg

(Setting GRUB_GFXMODE didn't solve the problem for me.)
