7.1 Multihead Display

Problem  

My machine has more than one head. How do I display GNOME applications on the second head? 

Solution  

The GNOME Desktop installation process can detect machines with more than one head. Multihead displays should start automatically. You can also manually bring up an application on an alternate head by setting your $DISPLAY variable or launching the application with the --display=:0.n flag, where n is the display number.

If you use two identical frame buffers set for the same video depth, you can also modify /etc/dt/config/Xservers or /usr/dt/config/Xservers to run XSun in Xinerama mode. The GNOME Desktop then treats both video heads as a single logical display.
