when it fails can you use Ctrl F1 to get a terminal or is this broke as
well?
does this work?
To start into safe mode (Recovery Mode) hold down the Shift key as the
computer starts to boot. If holding the Shift key doesn't display the
menu press the Esc key repeatedly to display the GRUB 2 menu. From there
you can choose the recovery option.
and from the grub pages
GRUB VGA Modes
GRUB allows you to choose the VGA definition it uses when booting.
(Note: this does not affect the definition in Xorg).
You need to add the option vga=xxx on the kernel stanza in the
file /boot/grub/menu.lst.
Of course, replace xxx with the video mode you want. Your kernel stanza
will look like this:
kernel /boot/vmlinuz-2.6.18-6-686 root=/dev/sda0 ro vga=791
Here is a list of the available video modes:
Colour depth 640x480 800x600 1024x768 1280x1024 1400x1050
1600x1200
8 (256) 769 771 773 775
15 (32K) 784 787 790 793
16 (65K) 785 788 791 794 834 884
24 (16M) 786 789 792 795
pick a number from 769 to 884
