I use a Dell Vostro 1500 with a GeForce 8600M GT. I used to have lucid with gnome2 (of course) with a seperate x-server setting for my external tft. everything worked like a charme.
Then i switched to an SSD and did a oneiric reinstall. When installing any oneiric nvidiadriver and setting up the seperate xserver setting i get the same issue with black (or white when i click around) screen on the external tft. Mouse apears as the low-graphic X, nothing of unity is shown, nothing is clickable. Twinview works, BUT like #66 its ugly slow. compiz and Xorg are using >10%cpu each, scrolling in chromium gets laggy, shoving programs between ext. and laptop screen laggs and switching to fullscreen takes several seconds. It is like using an old pentium 2 :/ this is the bug with the seperate xscreen. its unity related like this one. https://bugs.launchpad.net/ubuntu/+source/nvidia-settings/+bug/882143 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
