I found this from a similar question:
The trick is to separate the 2 screen by a virtual space in xorg.conf , then use a tool called mouse-switchscreen to "jump" between the screens.
My config: Ubuntu 10.04 x64, ATI Mobility RadeonHD , ATI Catalyst Control Center correctly installed, screens in mode "Single Display Desktop" (each screen has it's own Desktop)
These are the steps that I made:
- Download dualscreen-mouse-utils from
- Decompress the package, in terminal type: make , you may need to xorg-dev package (in Ubuntu:
sudo apt-get install xorg-dev )
- Copy the mouse-switchscreen binary to folder included in PATH (I used
- Start gconf-editor (Alt-F2), in apps\metacity\keybinding_commands choose an empty command, and add:
mouse-switchscreen -f 1
- In gconf-editor apps\metacity\global_keybindings choose the same number for run_command_n and add a shortcut of your choice, personally I entered:
- If everything is working, Edit
/etc/X11/xorg.conf (better make a backup before), in the "ServerLayout" section, change the position of a screen to make the two separate. ONE pixel is enough :D
You can now
sudo /etc/init.d/gdm restart and enjoy. Of course, Win+Tab to switch the screen. You can also try mouse-wrapscreen, mouse-wrapscreen -h for more info.
