I am using a dual independent GPU setup comprised of two NVIDIA GTX 285 cards on OpenSuse 11.2. I am feeding these two cards to four monitors using separate Xsessions for each monitor and Xinerama to combine them into a single X screen (spanned 4 wide). I have the ability to span all 4 monitors and use all 4 of them normally with one exception: the KDE functionality only works on the first monitor (i.e. I cannot configure the background or maximize windows to individual monitors). If I maximize a window that is in a non-primary display, that windows will fly over to the primary display and maximize there. Has anyone seen this behavior before? Thanks for any advice you can provide.
