I'm running on a Asus notebook with a Mobility 9600 (M10) gpu. The lvds display is 1280x800 native and I have an attached 22" 1680x1050 native display to crt1.
When at home, I want to run my laptop with the lid closed -- no lvds display -- and solely run on the crt display. As recently as Catalyst 8.2, I could specify Option "ForceMonitors" "nolvds,crt1" and everything would work perfect. OpenGL ran and Xv video also ran, both at the native 1680x1050 for the external display. After upgrading to Catalyst 8.3, this is no longer the case. I can not get native resolution on the secondary display when ForceMonitors or EnableMonitor options are listed.
If I remove the ForceMonitors and EnableMonitor options I will get native resolution on both displays. However, Xv video only will work on lvds. I looked at the Xorg.0.log and it shows that when ForceMonitors or EnableMonitor is specified, the EDID or DDC for the crt1 montior isn't detected correctly:
Here is what is detected when ForceMonitors/EnableMonitor isn't specified:
I really hope ForceMonitors returns to it's old functionality in the next release
[Edit] I think I fixed it further down in the thread. PEBKAC
