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. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/813343 Title: nvidia drivers, second monitor covered by black To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/813343/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
