I finally took the time to upgrade my Ubuntu install to the recent
release 12.10 (Quantal Quetzal). This bug still occurs, and now seems
worse then ever. I have skipped (i.e. not tested) the releases 11.10 and
12.04, but I assume those two releases didn't bring any improvement
either.
In the past, I've set my builtin monitor (laptop) to a smaller
resolution (1680x1050). That way I could run the external monitor at
full resolution (1920x1080 full HD) even with nvidia-current driver.
Remember: both screens worked fine with full resolution with nvidia-173
(slower) as well as with nouveau (even more slow).
Under Quantal, nouveau cannot handle both screens at full resolution and
neither can any of the provided nvidia proprietary drivers. I tested all
available options: -current, -current-updates, -experimental-304, and
-experimental-310.
I think nouveau managed to run both screens in "mirror"/clone mode, but not
sure about the exact resolutions was using.
What's worse, I cannot set my laptop monitor to the smaller resolution like I
did in the past, since only "Off", "Auto", and "1920x1200" are shown in
nvidia-settings as well as in 'Display' system settings (that's using randr,
right?).
Both monitors run, when I set my external monitor to a smaller resolution
(currently 1680x1050), but that's not the native resolution and not the correct
aspect ratio (16:10 vs 16:9).
And if that was not bad enough, Xorg cannot even start when the external
monitor is plugged in. The screen will blink several times and then dump
to a black screen with a blinking white cursor. Switching to a VT,
unplugging the monitor and starting X (service lightdm start) will
finally bring Xorg back up. This is really annoying! (Please imagine a
turned on caps lock, to get an idea of my frustration).
The external monitor is connected with a VGA cable if that matters. I
cannot use DVI, because my laptop only offers VGA out.
Relevant details from Xorg.0.log after unsuccessfully trying to start X

If you need more information about my system, please ask and I will
provide it. This bug has existed long enough and I really like to have a
working multi-monitor/dual-head setup.
