Raw

Edit /etc/default/grub file

sudo nano /etc/default/grub

Edit the GRUB_CMDLINE_LINUX_DEFAULT flag to add nomodeset and vga=795. Change vga modeset accordingly. You can reference the table below.

Color Depth	800x600	1024x768	1152x864	1280x1024	1600x1200
8 bit	vga=771	vga=773	vga=353	vga=775	vga=796
16 bit	vga=788	vga=791	vga=355	vga=794	vga=798
24 bit	vga=789	vga=792		vga=795	vga=799

It should look like this

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset vga=795"
