1.0-4349 Xinerama screen number assignment bug

[dkosovic]

Hi,

I think there may be a driver 1.0-4349 bug with the Xinerama screen number assignments for 2 seperate screens configured as per Appendix R : "Configuring Multiple X Screens on one card". No matter what I do, I can't get the primary display (i.e Quadro4's video connection 1) to be Xinerama screen 0.

Setup:

Redhat 9.0 / driver 1.0-4349 / kernel 2.4.20-8smp
Quadro4 900 XGL (using DVI to HD15 VGA adapters)
Video BIOS 04.25.00.27.05
Dell Precision 450 - dual Xeon 2.4GHz, 1 GB Ram


Using the following configuration from Appendix R:

Section "ServerLayout"
...
Screen 0 "Screen0"
Screen 1 "Screen1" leftOf "Screen0"
...
EndSection

and changing it to:

Section "ServerLayout"
...
Screen 0 "Screen1"
Screen 1 "Screen0" leftOf "Screen1"
...
EndSection

makes no difference. In either case, Xinerama screen 0 always corresponds to the Quadro4's physical second video connection. I've also tried other permutations elsewhere in the XF86Config file with no effect.

The same XF86Config under the previous driver & RH8.0 worked correctly.

In my setup I also have two NV17 MX420 PCI cards and I can make one of the PCI cards Xinerama screen 0, but it seems impossible to be able to make the Quadro4's primary display have a Xinerama screen number less that of it's secondary display.

Thanks,
Doug.
