okay, I think, I got it: changing Option "metamodes" "CRT-0: nvidia-auto-select +0+0, CRT-1: nvidia-auto-select +1280+0" to Option "metamodes" "CRT-0: nvidia-auto-select +0+0, CRT-1: 1280x1024 +1280+0; CRT-0: nvidia-auto-select +0+0, CRT-1: 800x600 +800+0" in section "Screen" should work. I didn't try it yet, so if enyone got a veto, post it [Wink]
