Bug Description
Binary package hint: grub2
Hello!
I've tried setting GRUB_GFXMODE=
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.)
