I also found editing the
GRUB_GFXMODE=640x480 settings fixed the problem. However, first, I had to add the
Optional, if step 1 doesn't work
sudo add-apt-repository ppa:danielrichter2007/grub-customizer
sudo apt-get install grub-customizer
sudo apt-get update
- Find Grub Customizer in the GUI (for me it's in System>Administration>..., but for some it is fund under Applications>System Tools>..)
- Open Grub Customizer and select Preferences > Advanced
GRUB_gfxmode (640X480) - if it is already selected, deselect it, reboot, and select it again.
- Cross your fingers and reboot!
I have no idea why this worked for me, but it worked on both of my computers, so hopefully it will work for you too!
