24" iMac (Intel, Nvidia) Dual Monitor Problem
I'm installing OpenSuSE 11.2 (KDE 4.3.5 and Xrg 7.4) on a 24" Intel Core2 Duo-based iMac (iMac 6.1 / EMC# 2111) with a video card that's showing up (lspci) as "nVidia Corporation G73 [GeForce 7600 GT]".
I've got the OS installed and running. Everything looks fine on the main 24" display. However, I've plugged a 20" Apple Studio display into the external monitor port. It's not being seen by any software (Sax2, KDE Control Center, etc.) and is showing a garbled image (like what you'd get if you pushed the 1920x1200 res for the main display onto the 20" one).
At the moment I don't have any proprietary nvidia utilities or drivers installed. I want to be able to do dual-head with xinerama/continuous desktop. Any experience with this hardware, or any tips?
