Also, I can say for a fact that simply re-installing the drivers will not reset the system back to where mine started with the fresh install.
While I was trying to fix my problem last weekend, I tried uninstalling/re-installing the drivers but it would end up right back to the same garbled out of sync image on my TV. No scrolling 640x480 display. It had retained whatever f'ed up screen settings.
The only way around this is to find all of the settings locations.
Also, does anyone know how Ubuntu stores the current screen resolution? (from going to the built in menu to change resolutions) I also see resolutions show up in that menu that are not in my xorg.conf file including the 1152x648 res that I'm using.
