I am having issues setting up my machine to use quad monitors. This was all working fine in 11.04 but since upgrading I have had no luck getting the configuration to work. If I use the same xorg.conf as I had working in 11.04 I get 4 clones of the same image on the monitors. Not only this but if I click on an icon such as firefox in the launch bar, X restarts. Getting two monitors working is simple and if I just remove the xorg.conf Ubuntu is able to detect the two monitors and set them up correctly.
I am not bothered about any fancy effects but it would be nice if I could get the system up and running with four monitors as I had before. I am not using the ati drivers, just the open source radeon driver as one of my cards isn't supported by the newer ATI drivers. I am using two different ATI cards on the system :
01:00.0 VGA compatible controller: ATI Technologies Inc RV516 [Radeon X1300/X1550 Series]
02:00.0 VGA compatible controller: ATI Technologies Inc Mobility Radeon HD 3600 Series
The xorg.conf is shown below:
