It's Open GL to blame as it can't handle more then one display. If you use NVidia cards with their proprietary driver and thus have to use NVidia's twinview, you don't have that problem as twinview will present itself as one display with huge dimensions. But even my quadcore Intel box will kind of crawl when using an OpenGL app such as bzflag.

I'm not really concerned with games. I have only one app that uses 3D - Google Earth. If that runs smoothly (on one screen) I'd be happy. For some reason (it might be shortage of video mem, I'm not sure), it doesn't work if I maximise it on the second display. If I widen the window to extend accross both screens, it's fine until it reaches about half of the second screen, than the "earth window" goes black.

What drives me more nuts are two applications that, when I maximise them, don't stay on one screen: VMware and MPlayer. Both enlarge to the size of one screen, but sit in the middle of the two. This is completely useless. I have fiddled endlessly with xorg settings and KDE's window manager settings, but all to no avail.

AFAIK - you can not have 3d accell on more than one screen, I think I read something like this on nvidia forums. Anyway, I could never make it run on both screens. Well, on my work box (Radeon 7000, the the default xorg/kernel driver, and two 19" screens at 1280x1024 each) I'm using FBmerge. My xorg.conf doesn't even have a definition for the second monitor. I can open glxgears and drag it to the second screen, and it continues to run

VMWare is not yet xinerama-capable. According to posts on their forums, this is planned for some future release. As a workaround, use the QuickSwitch mode. That makes it a little better - at least I can put it in 1024x768 now without having to scroll.

For Mplayer, use -xineramascreen option. Great! That solves that one. Thanks!
