Use Dual Monitors NVIDIA Quadro 350M Natty?

Asked by JayBofMA

Since "upgrading" to Naty I can no longer user dual monitors corectly.

SeparateX with Xinerama does nothing more than display the same desktop on the second monitor; I cannot use that desktop
SeparateX without Xinerama is no beter
TwinView is not desireable as I have a laptop with a larger secondary monitor, and TwinView behaves poorly; in fact I cannot properly configure the position of the second monitor.

This is all in contrast to Maverick which was working well until I performed a security update last week, and Nautilus was so fragile, I could not use the machine at all. I thought that I would be better off accepting the 11.04 upgrade. But I was rudely surprised.

Must I continue to use Windows XP to have a stable platform?

Dell Precision Workstation M65
NVIDIA Quadro FX 350M
Intel Core 2 Duo
4GB DDR2
GRUB/WUBI

I have added the link, although the behavior I see is not entirely like that in the bug. However much of the discussion by the various posters is similar enough to make me think this is s a nagging issue with some history.

Uninstall the nvidia driver and reboot, then reinstall the nvidia driver then reboot

Proprietary drivers often survive large kernel changes which occur in release changes. Sop this sort of thing can help a lot

I attempted to follow these instructions, but was not very successful. I ended up removing NVIDIA and Nouveau drivers both. Even then, I was not able to get Separate X to work correctly. I even tried the x64 Linux drivers from NVIDIA.com with little or no better success (which forced the defualt Noveaue drivers to be disabled). In the end, I found the issue to be the xorg.conf file generation.; the only way I could get X to work correctly was to manually modify xorg.conf.

Any attempts to use the GUI to modify the xorg.conf were unfruitful. If I corrected Monitor 0 to be correctly noted as RightOf, rather than Absolute, that would be fine, but the resolution and position offset were lost. If I then tried to change thes other values in the GUI, one or the other would be lost. etc., etc.

I finally modified the xorg.conf by hand and created a backup of my own, for safe keeping.

This has been very dispiriting. As it does not seem to be a driver issue at all, it is an Ubuntu and/or NVIDIA Settings implementation issue in the GUI. Hopefully these two can resole this issue.... And it would be better at a patch level than at 11.10!

I have more work to do with xorg.conf... Windows moved to Monitor 1 hang when I interact with them with the mouse and/or the keyboard. I seem to be able to raise the window menu via the keyboard, however, so that I can "Move" it back to Monitor 0. But I am not sure this is any improvement over the earlier mirrored display scenario.

The issue is with attempting to use a compositing manager for Docky. Switching the compositing manager off and usng Unity 2-d rather than Docky has solved the major issues. Using other threads for reminaing issues.
