http://serverfault.com – I have a problem in my AMD Condor Dual-Head Graphics Card When I enable Xinerama from "System->Preferences-> AMD Catalyst Control center (Administrative)" my RHEL Server 6.3 (x64) Graphics hangs. I need to choose disable it from console (Alt+Ctrl+F2), login as root, off Xinerama from xorg.conf Because of this i am not getting 2 separate displays :0 and :1. While switching from initlevel 3 to initlevel 5 i got following error. Loading TSI condorvc device driver moduleinsmod: error inserting '/lib/modules/video/condorvc-mod.ko'': -1 File exists (HowTos)
