Hi misc,
Just wondering about any success stories getting dual-screen/xinerama
running under OpenBSD 4.2-release with nVidia cards (G73) under X. If I
read correctly the necessary code for this was imported by matthieu@
after 4.2-release code was frozen, so it should be in -current.
I can speak only of -current. Putting the following lines in your
xorg.conf should give you dual head with a few drawbacks:
Section "Device"
Identifier "GeForce 7600"
Driver "nv"
Option "Dualhead" "true"
EndSection
Section "Screen"
Identifier "Screen"
Device "GeForce 7600"
Monitor "Monitor1"
DefaultDepth 24
Subsection "Display"
ViewPort 0 0
Depth 24
Modes "1280x1024"
EndSubsection
EndSection
This will give you dual head with VBE. Using the xv extension will
freeze the X server and xinerama does not work. There is a patch around
to give a fake xinerama, I did not test that.
Another drawback is that both screens have to have the same mode
available. But my flatpanels with 1400x1050 won't work either and the X
server will give me both screens on 1280x1024. This results in an ugly
scaled flatpanel picture that really hurt the eyes.
So it somewhat works, but only up to 1280x1024 on my 7600GT for each
screen and without the xvideo extension.
I decided to put another pci card into the computer to have a dual screen
which actually works. Putting another nvidia card into the second PCIE-16x
slot resultet in a non starting X server.
It would be really nice to have working dual head support for my card but
I don't think that this will happen in the near future.
Kind regards,
Markus
