Hello to all. Hope you are well.
Sorry for this long post, but I'm stumped. I've been reading and
experimenting for most of the day and think I could use some help.
My monitor is a Viewsonic VX2250wm-LED connected through a KVM.
Ubuntu 9.10 on a Intel 4 series integrated graphics controller achieves
1920x1080 with no X conf files.
I just installed Ubuntu 10.10 on a Biostar G31M board with a Intel
82G33/G31 Express Integrated Graphics Controller. The max res it can
achieve is 1024x768.
I tried Ubuntu 11.04 and got the same result.
I compared the EDID data from both machines and it is the same. The
i915 driver thinks it is invalid on the G31 although it appears to be
the same as what the other machine sees.
From the G31 board ...
