[gentoo-user] Graphical issues on intel gfx card

Hi all,
I'm having a few problems with my graphics on my gentoo laptop. The laptop
is a Sony VPC-Z13 with hybrid graphics but I have it forced to purely use
the intel card. When I boot into GDM I have around a 5 second delay where
the screen exhibits odd corruption but once loaded all seems fine. I have
found that when loading wine applications the same corruption happens
whilst they load but once loaded are fine. I have noticed that in
Xorg.0.log when the corruption occurs the following is output twice:

[   982.687] (II) intel(0): EDID vendor "MS_", prod id 37
[   982.687] (II) intel(0): Using hsync ranges from config file
[   982.687] (II) intel(0): Using vrefresh ranges from config file
[   982.687] (II) intel(0): Printing DDC gathered Modelines:

[   982.687] (II) intel(0): Modeline "1920x1080"x0.0   99.91  1920 1952
1984 2281  1080 1083 1086 1095 -hsync -vsync (43.8 kHz)
[   982.687] (II) intel(0): Modeline "1920x1080"x60.0  172.80  1920 2040
2248 2576  1080 1081 1084 1118 -hsync +vsync (67.1 kHz)

Any help with this would be greatly appreciated. Thanks!

Oliver
