Title:
grub console is ridiculously slow
Status in grub2 package in Ubuntu:
Confirmed
Bug description:
Binary package hint: grub2
Hello!
I've tried setting GRUB_GFXMODE=1920x1200 in /etc/default/grub, as
this is the native resolution of my screen.
This works, in the sense that the GRUB menu is displayed in that
resolution. However, the display is really, _really_ slow. I can see
the borders being drawn on the screen (it takes about a second). And
scrolling is unusable: if I use the GRUB console enough to fill the
screen, it takes about six second to scroll to each next line. This is
on an nVidia GeForce 9600 GT.
Note that if I set the same resolution for the Linux text console
(which works, through vesafb as far as I can tell), scrolling is still
slower than text mode, but still usable (I'd say about a second or
less to scroll an _entire_ screen, not six seconds _per_line_ as GRUB
does).
(I've seen this reported as a side note in other bugs, but I can't
find a duplicate bug on this problem only.)
