Comment # 10 on bug 1101747 from Felix Miata

YaST touch on 27 Sept on host ab250 removed "#" from GRUB_TERMINAL line start,
and cursor from Grub's edit screen. My intent was a cursory UEFI RAM redo after
having done a temporary disk swap for a temporary installation. Restoring the
original SDD removed the opensusetw entry from the firmware. /etc/default/grub

Rerunning 'grub2-mkconfig -o /boot/grub2/grub.cfg' after putting the "#" back
on the GRUB_GFXMODE line did not fix the problem this time. :-(
