Version: (using KDE 4.4.1) OS: Linux Installed from: Ubuntu Packages Triplehead setup with three screens hooked up to two nvidia cards configured with Xinerama On, RandR off, composite off. Nvidia proprietary driver. Keybindings for switching screens in global keyboard shortcuts are not fully working: 1. The key combination used to switch to the first screen (Screen 0) is always parsed correctly. 2. The key combination used to switch to the second screen (screen 1) is assigned to the last used screen of the remaining two (screen 1 or screen 2). 3. Key combination for the third screen (screen 2) is _not_ parsed. This behavior limits the possibility to switch only between two screens. The second screen (screen 1 or 2, depending on which is the last used of the two) is reachable only with the key binded to screen 1. On a standard dualhead setup key bindings are working as expected.
Sorry for the delay. Are you still interested to resolve this issue? (it will take your assistance since likely no KWin developer has a triple screen setup)
