Hello list,

I have a small box with a quad 64-bit Celeron and integrated graphics During 
boot, the UEFI screen is fine, but as soon as the kernel starts, it switches 
the background to a dark grey; I can't tell whether the white is properly 
white because of the grey background. I don't see anything wrong with the VT 
colours, and X11 seems unaffected too with XFCE. I assume the problem lies in 
the kernel.

Can anyone suggest what is wrong with my setup? Google doesn't help me.

I have what I think are the right kernel settings for th I915 driver. For 
instance, from kernel help:
This option gives you AGP support for the GLX component of X
on Intel [...] and I915 integrated graphics chipsets.
