Bug Description

Binary package hint: grub2

When I use "GRUB_GFXPAYLOAD_LINUX=keep" in /etc/default/grub, I only get a blank screen after selecting the kernel and it doesn't boot. I could fix this by manually inserting "insmod vbe" to grub.cfg or adding "GRUB_PRELOAD_MODULES=vbe" to /etc/default/grub. This should be done automatically when GRUB_GFXPAYLOAD_LINUX is set, for example by adding it to /etc/grub.d/10_linux:

*** /etc/grub.d/10_linux 2010-03-23 14:39:17.952327708 +0100
--- 10_linux 2010-03-23 14:57:46.506358515 +0100

    if [ "x$GRUB_GFXPAYLOAD_LINUX" != x ]; then
     cat << EOF
+ insmod vbe
   set gfxpayload=$GRUB_GFXPAYLOAD_LINUX
  EOF
    fi

if [ -z "${prepare_boot_cache}" ]; then

Is it permittet to insert vbe twice? As I have gfxmode set here it seems that

insmod ${GRUB_VIDEO_BACKEND}

from 00_header already does that as it turns into

insmod vbe

in my grub.cfg. But I just can't seem to find out where GRUB_VIDEO_BACKEND gets set.

Can you please tell us the Ubuntu Release that you're using? I'm guessing it's Lucid from the GRUB_GFXPAYLOAD_LINUX option, but there the VIDEO_BACKEND module (set in /boot/grub/video.lst) is always inserted when
ogfxterm: gfxterm
is set in /boot/grub/terminal.lst

can you check what is set for you in /boot/grub/terminal.lst? Thanks.
(The patch should be changed to honor the GRUB_VIDEO_BACKEND, but I can do that once I get your feedback)

Erm, Ignore the ubuntu release question, I was so focused on the grub scripts that I failed to realise that you told us that already...

I just tested it again with version 1.98-1ubuntu6
Now it works without any modification, so I think this bug can be closed.
