Despite reading other posts on twinview, I can't get it to work on the second display- I want a single X screen over 2 x 1280x1024. I have a Quadro4 900XGL, and have loaded the latest nvidia driver (it looks to work OK). The OS is RH7.3. I am using the DVI to VGA adaptors as I am driving CRTs. Before trying Twinview option, I had the same screen on both displays, so hardware is OK. I'm fairly sure it is a metamode or syntax type problem, can anybody point out what this old idiot is doing wrong?
It looks like you have incorrect values sync values specified in XF86Config. You may want to double check the values. since you have EDID disabled.
What you have for monitor0;
What the card sees;
(II) NVIDIA(0): Monitor0: Using hsync range of 30.00-82.00 kHz
(II) NVIDIA(0): Monitor0: Using vrefresh range of 50.00-75.00 Hz
For the second monitor
What you have;
Option "SecondMonitorHorizSync" "30-82"
Option "SecondMonitorVertRefresh" "50-75
What the card indicates;
Default mode "1280x1024": 135.0 MHz, 80.0 kHz, 75.0 Hz
Here is what I have with a 750 XGL connected to two CRT's
Option "TwinView" "true"
Option "TwinViewOrientation" "LeftOf"
Option "SecondMonitorHorizSync" "30.0 - 78.0"
Option "SecondMonitorVertRefresh" "50 - 130"
Option "MetaModes" "1280x1024, 1280x1024"
That fixed the problem!! I had copied half of the config file from a working dual-TFT file, but naively thought it wouldn't matter.....many thanks!!
