Public bug reported:

I originally posted this as a question...

... where it was suggested that I submit a bug report instead.

I can't get TwinView to work correctly on a Dell Precision M6500 laptop
with Nvidia Quadro FX 3800M. I'm initially testing with the laptop's
built-in screen + a LCD connected via the VGA port. It half works with
the open-source Nouveau driver (clone only) and half works with the
proprietary Nvidia driver, but either cause X lockups on mode-switch or
one screen to be blank. The hardware is fine, since it worked when I
tested with the original Windows installation that was on the laptop.

The symptoms are:

1. Nouveau driver
1.1. Clone works fine, e.g. installer / live trial + installed
1.2. Extended desktop causes either the laptop screen or the panel to be blank

2. Nvidia driver
2.1. Single screen works fine - no problems
2.2. TwinView causes either the laptop screen or the panel to be blank, depending on X configuration. I can easily choose which one ends up being blank by prioritising the other with the "UseDisplayDevice" config option.
2.3. When trying TwinView, the initial mode-switch causes the above #2.2 symptom, then the 2nd mode-switch back causes X to lock up (either automatically via the time-out because I can't see the original dialog box, or choosing to manually switch back)
2.4. When booting up with TwinView configured and the panel plugged in, the login box ends up on the wrong display.

I've tried the above with fresh installations of Ubuntu 10.04 LTS
32-bit, Ubuntu 11.04 64-bit and Ubuntu 11.10 beta 2 64-bit. I've tried
changing the Nvidia driver from v270.41.07 (that's installed with Ubuntu
11.04) to rolling my own nvidia-current with latest Nvidia stable
v275.28, then I also tried the latest v280.13.

I've looked through all the forums, FAQs and Ubuntu help I could find,
including the following:

https://help.ubuntu.com/community/BinaryDriverHowto/Nvidia

I noticed that the M6500 is on the Ubuntu certification list, but with
32-bit and ATI graphics instead of Nvidia. There's also a hardware
certification page here for up-coming 11.10 which shows some failures
for the M6500, but I can't see which configuration or what the failures
are without being able to login...
