I was able to install Nvidia Driver 346.35 (as it was the latest version available in the repository), the situation is indeed beter. The graphics is no longer corrupted. I am able to use my monitor positioned on the left side.
There is however one issue, the screen is visible to Ubuntu as a single, big instance instead of two separate screens. I mean that if I make a window full screen, instead of going full screen on the monitor on which it is positioned, it spans accross two monitors. Additionally I don't know if that's relevant, but Ubuntu's Display tool sees correctly two screens while nvidia-settings shows only one (which is incorrect), please see attachment. PS. I am running Vivid build from 1st of March. ** Attachment added: "onevstwo.png" https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1305264/+attachment/4331384/+files/onevstwo.png ** Changed in: xorg (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1305264 Title: Incorrect display when using monitor on the left on NVIDIA Optimus Card To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1305264/+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
