Using Projector on Ubuntu

Using Projector on Ubuntu

These days, I have changed my operation system from WINDOWS7 to UBUNTU.

I met the problem when I wanted to use projector  in conference room.

First, you need to install the NVIDIA driver.

Second, connect your projector on your VGA port. Restart your x-window with the command:
left alt + k + Prnt Scr.

Third, open [system] --->[administration]--->[NVIDIA X Server Settings]---->
[X Server Display Configuration]----->
Change the Model part.
Click on the configure... and choose TwinView

Click 'Apply' at the end.
