[lug] Ubuntu upgrade to 9.10 and now my screen resolution sux

[bgiles]

I hope this is a quick fix - I finally upgraded my atom-based system to 
Ubuntu 9.10 and my screen resolution has dropped to 800x600.  It doesn't 
matter if I explicitly list higher modes and the preferred driver in 
xorg.conf.  (I'm no longer sure if that's the right file or if it's been 
superceded!)  What is especially annoying is that the screen resolution 
is clearly higher during the boot process but then it goes dumb when gdm 
starts.

xrandr only shows 800x600 and 640x480 modes so I don't think it's /just/ 
gnome, but who knows.

The video driver is an intel 82945G/GZ and other people have reported 
problems but none of the approaches seem to work.  Most notably they 
already have a higher resolution (1152x864) working.  I've also added 
the ppa:ubuntu-x-swat/x-updates but it says that I'm running the most 
recent versions of the drivers.

Thanks,

Bear
