I made the jump to Squeeze on this laptop with a minimum of problems. In fact, the only real issue of note was the shift to Grub2, which always confounds me.
So I can figure this out with less effort in the future, Grub2’s configurations in Debian are at /etc/default/grub. Adjusting this line to read
and adding this line
gave me proper screen dimensions all the way through the boot process. Instead of snapping back at the end.👿 Why would that be necessary? I can only wonder.
Actually enforcing those options will require
grub-mkconfig -o /boot/grub/grub.cfg
Until then, Grub just flaps its lips at you. But once that’s done, it works fine.
Surprising credit line of the day: Thanks to the Arch wiki, which had the information up front and easy to find. Cheers.
