Grub menu is not visible on startup due to wrong screen resolution

Asked by Richard Reinhart

Just updated to 12.04 and on start up on a dual boot system, the menu selection is not visible apparently due to wrong screen resolution. Do I need to somehow make a change in the startup file to set the screen resolution so it is visible?
Thanks

What is the output of:

sudo apt-get install v86d hwinfo; clear; sudo hwinfo --framebuffer

Yes, they have high resolutions working for the grub now, but the characters are so tiny they are almost unreadable. Edit the grub config file and then run update-grub:

sudo nano /etc/default/grub

and uncomment the line that reads "GRUB_GFXMODE=800X600

I found 1024x768 also works now, and looks pretty good but 800x600 would be 'safe'. You'll then need to update the grub menu file:

sudo update-grub

On the next boot you should a readable grub menu.
