I don't think having multiple unconnected screens that you can't move windows between is at all interesting. We're basically just not interested in spending effort to make that work better. > If you have a reasonably current nVidia adapter you can get 'working' > multi-head using the nvidia-settings application using TwinView.

If your nvidia card isn't *too* recent and you don't have strong needs for full-featured/full-performance 3d, the nouveau drivers work pretty well and are configured through the standard GNOME tools. > This issue is frustrating because it is nearly impossible to figure out > even what *should* work.

This is a hardware limit. The only hardware with such limit likely to be encountered Intel 945 (and older): horizontal limit of 2048 pixels Radeon R300 (and older): limit of 2560 pixels (Of course, newer hardware has limits too, but they tend to be 4096 or 8192 pixels, so affect far less configurations.) R300's aren't found on anything remotely close to recent; but the Intel 945 are still fairly common. But more in netbooks than on anything that I'd consider normal for "scientific computing" or "development". - Owen _______________________________________________ gnome-shell-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gnome-shell-list
