This is a really good point. In this situation I probably would have
just gone to a tty and edited the grub conf file to default to an older
kernel if that happened, rather than play whack-a-mole with the grub
timeout.
Garbled video is an edge case, but it's a realistic one for any distribution that
aggressively pushes new kernels.
When changing video resolutions, the same thing could happen. At the time the resolution
changes, at least on Gnome, Windows, OS X, a dialog appears with options to Accept or
Revert the change, Revert as a default, as well as a timer. If the user doesn't
explicitly accept the change with a mouse click, the change is rejected just in case the
video is garbled.
Perhaps something similar can be leveraged for a one time boot, just to ensure at least
video is functioning?
