Hi Folks

I finally got Xinerama working on my RH9 Box, however I come across a problem regarding setting the desktop resolution on the second monitor. Any ideas you folks can throw at this are appreciated!


Problem

I can't seem to set the secondary monitor resolution to 1024x768 with high colour depth, its currently stuck at 640x480 - 256 colours.


Physical Setup

Primary Display - AGP GeForce 2 GTS -> 17" ADI Monitor
Secondary Display - PCI Savage4 -> 17" ADI Monitor


Software Setup

Red Hat 9 - Kernel 2.4.20-18.9
XFree86Verion - 4.3.0

Cheers for any input ..... Svha !

I don't know much about this... but I would have doubled up on NVIDIA cards instead of going with NVIDIA and S3.

maybe try adding some modes for the secondary monitor....

Okies ...... after a little tweaking I actually got this working (see XF86config below) I did change the secondary monitor to a 17" Gateway (picture quality)

So it now looks like this .....

Display 1 -> AGP GeForce2 -> ADI 17"
Display 2 -> PCI S3 Savage 4 -> Gateway 17"

However what I dont understand is, that if I had listed several display modes for "screen 2" instead of just hard setting one - ie ......

Modes "800x600" "1024x768" "1152x864"

Which one X would use - is there a pointer in another config file that determines this?

Cheers ..... Svha
