1366x900 is a seriously uncommon resolution. I wonder if Gnome, Xorg or driver
devs even know it exists? Does xrandr -q confirm it's what you have? According
that model only comes with 1366x768 screens.

Gnome is very demanding compared to other DEs. If GDM is still installed,
removing it might help. Make sure to configure trinity-tdm as your display
manager. I have lots of openSUSE installations with KDE3 or TDE, none on
laptops, but several with dual displays available. None have ever done as you
describe, and GDM is never installed.
