I'm having the same symptom as that of Michael, #34.  Also a Quadro
card.

I cannot get Twinview to work since I upgraded to Ubuntu 11.10.  My
computer is a Dell Optiplex 960, with a Dell-supplied nVidia Quadro NVS
420 card, connected via DVI to two Dell 2009W monitors.  Until Monday, I
was successfully using my two monitors in twinview mode, using the
nVidia restricted driver, and Ubuntu 10.04.  On Monday, I performed a
step-wise upgrade to 11.10.  Since that time, I have not been able to
get dual monitors to work.  A single monitor setup with the nvidia
driver works fine.  When I use nvidia-settings to enable the second
monitor, and then reboot, the second monitor initially flashes the
normal ubuntu desktop color, and then immediately goes to a grayish-
white screen.  If I move the mouse pointer to the second monitor, the
pointer changes from an arrow to the old X-windows "X" pointer.  If I
right-click the screen of the second monitor, it will change to the
normal color.  But doing anything else causes it to go white again.
Also in this mode, Unity running on the primary screen behaves oddly.
For example, files sitting on the desktop cannot be moved with the
mouse.  Another notable point is that when I use nvidia-settings to
enable the secondary monitor, the "Twinview" choice is shaded and not
available.  I tried purging all nvidia files with apt-get and removing
xorg.conf to start over, and then installed nvidia-current from PPA, but
it did not help.  I am running 64-bit Oneiric, and the nvidia driver is
285.05.09.

For now, I am using a single monitor, hoping that this is a bug that can
be fixed soon.
