I am running 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux with the FirePro 2460. This is a single GPU with 4 heads. I can get 3 monitors working fine each running under a different xserver DISPLAY name, :0.0, :0.1, :0.2. When I add the fourth monitor, I end up with the following error in Xorg.0.log
[4.063] (EE) fglrx(3): Display Infrastructure Failed Due to Hardware Limitation
[4.063] (EE) fglrx(3): PreInit failed
Is this the correct place to pose this question? I have attached xorg.conf and Xorg.0.log if anyone can direct me to an answer or the correct place to ask the question.
Thanks, Donald Kayser
