Bug#560978: grub-pc: Boot menu visible on only part of the screen when GFXMODE is set

[Fabienne Ducroquet]

Package: grub-pc
Version: 1.97+20091210-1
Severity: normal

When I set GRUB_GFXMODE to one of the modes available on my computer, 
only a part of the boot menu is visible. It's as if the boot menu were 
first displayed on the whole screen (with the correct resolution), then 
part of the screen were hidden.
With the configuration below, I can see only about 1/4 of the screen 
(the upper left corner). I can choose the boot entry (but if I had 20 
entries I could not see all of them), but I can't see the help at the 
bottom of the screen. This happens only to grub, once the boot starts 
the whole screen is visible with the correct resolution.

This behaviour appeared a few months ago when vga=... stopped working 
and I had to switch to gfxmode/gfxpayload, but after having spent time 
to find how to replace vga=... I was happy to have it almost working 
again and didn't spend more time to file a bug report.
