Bonjour,

I am facing a resolution problem with grub2.

Install of Fedora 21

grub version: grub2-2.02-0.13.fc21

Here is my /etc/defaul/grub:

<--------------------
GRUB_TIMEOUT="10"
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT="0"
#GRUB_SAVEDEFAULT="true"
GRUB_DISABLE_SUBMENU="true"
GRUB_TERMINAL_OUTPUT="gfxterm"
GRUB_CMDLINE_LINUX="rd.md.uuid=81f15cb5:748fb5c1:42bef1a6:1ea1ce47
rd.lvm.lv=fedora/usr rd.md.uuid=4a28174a:f38b4938:233f85f7:6ce585a8
rd.lvm.lv=fedora/racine rd.md.uuid=9f878179:a58f5c78:f645e22e:d7d3c896
rd.lvm.lv=systeme/swap rhgb quiet"
GRUB_DISABLE_RECOVERY="true"
GRUB_GFXMODE="1280x1024x32"
GRUB_GFXPAYLOAD_LINUX="keep"
GRUB_BACKGROUND="/boot/grub2/themes/system/fireworks.png"

#GRUB_THEME="/boot/grub2/themes/system/theme.txt"
export GRUB_COLOR_NORMAL="light-gray/black"
export GRUB_COLOR_HIGHLIGHT="magenta/black"
GRUB_FONT="/boot/grub2/unicode.pf2"
<-------------------------

So, as far as I read the grub doc, because of
GRUB_GFXPAYLOAD_LINUX="keep"

It is supposed to apply the 1280x1024 resolution to the console during
the boot. But it is not the case! I get this resolution only with the
grub first screen: fireworks image and the entry list.

What is missing in my config?

Strangely, I have a "custom file": /etc/grub.d/40_custom, to boot a
debian install:

<-------------------------------
  menuentry 'Debian GNU/Linux, avec Linux 3.2.0-4-amd64' --class
debian --class gnu-linux --class gnu --class os {
        load_video
        set gfxpayload=keep
        insmod gzio
        insmod mdraid09
        insmod part_msdos
        insmod part_msdos
        insmod ext2
        set root='(mduuid/eb8b5efe5a8f9369e940a0f383d63ad1)'
        search --no-floppy --fs-uuid --set=root
17e0b155-4d77-4769-b568-723329c5f656
        echo    'Chargement de Linux 3.2.0-4-amd64 ...'
        linux   /vmlinuz-3.2.0-4-amd64
root=/dev/mapper/debian-deb--racine ro  quiet
        echo    'Chargement du disque mémoire initial ...'
        initrd  /initrd.img-3.2.0-4-amd64
}
<-----------------------------------------

In that case, the "set gfxpayload=keep" instruction succeeds to give
the correct resolution during the debian boot.


Thanks for any help and suggestion.
