What is Disper?
Disper is an on-the-fly display switch utility that automatically detects all connected displays and gives you the option to either clone using the highest common resolution, or extend the desktop to the connected extra monitors.
This would be very useful in cases of presentations using a laptop etc.
The latest Disper release is version 0.3 and unfortunately it currently supports Nvidia only :(
Ubuntu users type the following on a terminal: sudo apt-get install disper
Fedora users type the following on a terminal: sudo yum install disper
The Disper extension will simply add a handy menu on the top panel to manage your displays easier and faster.
To use this extension, simply turn the switch to “ON”. Make sure you install the “disper” package first and that your graphics card uses Nvidia chipset. I am not sure about the drivers, but I suggest you try the proprietary one if you encounter any problems.
