855GM, xrandr-1.2, modesetting and BIOS panel size.

[Bjørn Haagensen]

Hi,

I've been trying to get this to work on my laptop, but with limited
success. It works fine on the external VGA connected, but the LVDS
only displays some kind of greyish pattern. I suspect it is due to the
driver not picking up the right panel size from the BIOS for the panel
based on my log files. Running xrandr I only get one valid mode
corresponding to the modeline below. If you need more info, please
tell me.

I read a post about a similar sounding (too me) problem, but hacking
the driver is above my skils.

Ubuntu Edgy.
