Introduction ------------ switchscreen is a program that switches the pointer of an X server between different screens that the server manages. It allows making a dualhead setup behave as two totally independent desktops, and toggling the screen by hitting some key. Compiling should only be a matter of typing "make" (provided the necessary development packages are installed). For usage information, type "switchscreen -h". Included is also a script, togglescreen.sh, which toggles between screens 0 and 1, and stores the position of the pointer on the other screen. Dualhead functioning -------------------- switchscreen can be used to switch between two independent screens of an X server, thus allowing two totally independent desktops using the same keyboard and mouse. You can then toggle between the screens using any hotkey you wish. To configure XFree86 for such operation do the following: 1. Configure your X for dualhead support (_without_ Xinerama!). 2. Define in the ServerLayout section the second screen's position to be farther away than the first screen's width. For example, if your first screen has a resolution of 1600x1200, you might define Screen "Default Screen" # 1600x1200 Screen "Secondary Screen" Relative "Default Screen" 1700 0 This stops the mouse from moving from the edge of the first screen to the second screen. 3. Configure your startup scripts to start a window manager on both screens (normally screens :0.0 and :0.1). Note that some window managers and/or desktops may have problems running two sessions for the same user at the same time. For instance, I use GNOME and sawfish on the primary display, and fvwm2 on the second. 4. Configure both window managers to run the script togglescreen.sh when you hit some hotkey, eg. alt-tab. Bugs ---- With version 0.1.0, in some cases switching to the second screen the focus doesn't immediately change to the window containing the pointer before it has been moved to another window and back. In version 0.1.1 a patch from Javeed Shaikh has been applied that reportedly fixes this problem. I have not tested the new version, and I recommend testing for yourself which version works better for you.
