config files, logs and pictures of configuration
Hi,
I am unable to create a working configuration with 4 monitors on 2 GeForce 450
(dual headed). I am able to make it working with 3 monitors - see
xorg.conf.tripple. The log file is xorg.0.log.tripple. The configuration works
also with Xinerama - see monitor-tripple.jpg.
When I add 4th display into the configuration (the same way as 2nd and 3rd) the
X doesn't start - see xorg.conf.quadro. No specific error message in the system
or xorg log - see xorg.0.log.quadro.
I also tried to configure it with proprietary nvidia drivers - I can start X
with 4 separate screens, but as soon as I enable Xinerama, the desktop is
"shifted" to the most right monitor and I must click on the first monitor to be
provided on the last one (even for two monitors) - see monitor-nvidia.jpg
(selection is on right monitor, a mouse cursor on the left one - so there is an
offset of a whole monitor). With 4 monitors the offset is 3 monitors :-(
So, I see it as a bug that I am not able to enhance a working dual
configuration into quadro one. Neither with nvidia nor nouveau drivers.
I have this config:
