I have a fresh installation of Ubuntu 11.10 32-bit. The hardware I am running is:
- Asus P5Q Pro
- 4GB RAM
- NVIDIA GeForce 9600GT
- 24" LA2405wg connected via DisplayPort (shared with other machine)
- 20" LP2065 connected by DVI (shared with other machine)
- Intel Core 2 Quad Q6600 @ 2.40GHz x4
When installed Ubuntu only uses the 20" monitor. The System Settings > Display utility sees both screens, but when I enable the 24" monitor, it complains about the refresh rate I have set (it flashes too quickly for me to see exactly what it says but it does mention 60Hz which is what it is using accoring to xrandr.
So I went to Additional Drivers and enabled what Ubuntu [Recommended] which was 'version current'. This failed to load so I went for (version current-updates). I then loaded nvidia-settings and configured the monitors as I wanted after a restart to activate the drivers.
After restarting, the 24" monitor showed a blank white screen (what is apparently a blank X Display) and the other monitor continued to work. This problem was my reason for rebuilding Ubuntu so I removed the driver and installed version 173.
Now in NVIDIA X Server Settings, when I click X Server Display Configuration to setup my monitors, it says:
Unable to load X Server Display Configuration page: Failed to query NoScanout for screen 0.
Why is this so difficult?! Which are the correct drivers to use?
I'm a newbie so please excuse me if anything above is quite right... I'm struggling :S
