Here is a list of features Xinerama support may or may not support: 1) Window placement 2) Icon placement 3) Menu placement 4) Menu position hints 5) Sizing menus for different screen sizes 6) Position of the geometry window 7) Maximizing windows 8) Limit SnapAttraction to windows on same screen. 9) Enable and Disable Xinerama on the fly (including modules) 10) Xinerama support in Pager 11) Xinerama support in WindowList 12) XineramaSupport in various icon managers (IconMan, WinList) 13) EdgeScrolling between Xinerama screens. 14) Handle Xinerama screens in Move/Resize parameters.
Currently, 3, 6, 9 and 13 are implemented. However some of the Xinerama functions poll the pointer position which reduces performance a lot, especially in the move and resize loops. Consider this layout of a Xinerama screen consisting of two physical screens: Xinerama screen +---------------------+--------------+ | | | | | | | | | | | | | | screen 2 | | screen 1 | | | | | | | | | | | | | | +---------------------+ | | blank area | | | | | +---------------------+--------------+ At the moment, the most annoying problems are: - Fvwm happily places windows and icons in blank areas. - Menus are sized for the whole screen. If a menu that is as tall as screen 2 is opened on screen 1, the bottom items are not accessible. - Maximizing windows always covers the whole screen, not only the sub screen with the window. In another step it may be worthwhile to put all code dealing with screen dimensions in a single library libs/Screen.c instead of libs/XineramaSupport.c. This libraray could handle all arithmetics with screen dimensions and would be the only place that knows about Xinerama at all. Any comments and help with the implementation are welcome. For those who don't have a second monitor I added the configure option --enable-xinerama-emulation. The Xinerama code is enabled on a single screen with the above layout, including the blank area. For testing, it is probably best to fill the blank area with a single window so you can see when the pointer or a window or menu reaches into the forbidden zone. You do not need the Xinerama extension in your X server for this to work.
