I finally found a solution/workaround (I can't believe it)!!!
A thread on the nvnews forums discussed a similar problem. One comment
suggested setting the option NoExtendedGpuCapabilitiesCheck in xorg.conf
to disable mode validation
I tested my graphics card with another external monitor (a Dell 2408WFP)
which runs with a native resolution of 1920x1200.
Using that monitor does not exhibit the bug and the driver/graphics card
is able to run two monitors simultaneously at 1920x1200 (total
resolution: 3840x1200). This shows me,
I just performed further tests with a system booted from an USB drive.
The bug happens regardless of architecture, both amd64 and i386 are
affected.
With the nouveau driver I managed to run both monitors with native resolution,
but the external monitor showed graphic errors (see the attached
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.

hi bryce,
no more luck without an xorg.conf, why would it? there's not much in my
config, except the driver.

much time and resources. i can try if desktop with effects works with
nvidia-173 driver, but i'm pretty sure it
Public bug reported:
nvidia-current is unable to use two monitors in full resolution (wuxga +

i think this bug does still affect me on natty, but i cannot test it

x-server ABI bump.
for the time being i avoided the issue using nvidia-173 installed via
apt-get – but i would appreciate it if jockey was able to install
