Bug#722551: Several display resolution changes during the boot sequence with Intel Ivy Bridge despite "fastboot" promise since xf86-video-intel 2.21.11

[thibaut bethune]

Package: grub-pc
Version: 2.00-18

Hi,

I've read carefully the xf86-video-intel 2.21.11 announce on the
Intel-gfx mailing list with its fastboot promise [1]

However i don't have it on my Ivy Bridge system [2] with
xserver-xorg-video-intel 2.21.15 - see my boot sequence video which
resizes here : http://libre-ouvert.toile-libre.org/data/documents/MVI_3575.AVI
(48,8 Mo, 26 sec)

Chris Wilson from Intel told me that this would rather be a bug within
Debian [3]

Julien Cristau (Debian X Strike Force) told me that it's not a bug in
the driver (Bug#722435)

Therefore maybe grub2 is concerned ?

I am using Debian GNU/Linux Sid with :
- Linux debian 3.10-2-amd64 #1 SMP Debian 3.10.7-1 (2013-08-17) x86_64 GNU/Linux
- libc6 2.17-92+b1

Thanks

[1] "the DDX will try to preserve the same display configuration as
used by the kernel, which hopefully will be the same configuration as
setup by the BIOS. The result should be a boot sequence that does not
resize at all (aka fastboot) - until the display manager takes over
and loads a completely different configuration"

I've attached the result of lspci and lshw commands

system doesn't boot to desktop under 2 seconds from after POST is a
distribution bug"
