About Disper





Disper is an on-the-fly display switch utility. It is intended to be used just before giving a presentation with a laptop, when all one wants is that the beamer, which has just been connected, is able to show whatever you prepared.





Disper gives you the option to either clone all detected displays, or extend the desktop to them. Resolutions are automatically detected. For cloning, the highest common resolution supported by all displays is chosen; for extending every display device gets its highest supported resolution. For special setups requiring more detailed control, one can still use the standard display configuration utilities. At the moment only NVIDIA cards are supported and disper is specially useful for those who have installed proprietary drivers.





Installation Instructions





You need to add both Disper and Disper-Indicator PPAs. Run the following commands below:





sudo add-apt-repository ppa:disper-dev/ppa

sudo add-apt-repository ppa:nmellegard/disper-indicator-ppa

sudo apt-get update

sudo apt-get install disper disper-indicator





Note: I haven't tested Disper on my system as I have ATI graphic card. But this should work nicely with NVIDIA cards as many users have reported on Ask Ubuntu.
