Getting Projectors to Work in Ubuntu

From: http://www.alterego7.com/2008/04/getting-projectors-to-work-in-ubuntu.html

1. Connect the projector to your laptop.

2. Do this in command line.

sudo dpkg-reconfigure xserver-xorg

3. Just press Enter through every screen.

4. Restart X for the changes to take effect by pressing CTRL + ALT + BACKSPACE.

5. Log in again as you always do.

6. And finally, the projector will automagically display your Ubuntu desktop and you can show off your desktop effects to your co-workers.
