Same problem here! - I have a Dell Precision M6800 - nVidia Quadro K31000M, driver version 331.113 - kubuntu 14.04, amd64 - xserver-xorg-video-intel 2:2.99.910-0ubuntu1.3
The extended monitor is splittted and shifted indeed and does not seem to have any acceleration. Visualization is laggy and even the mouse pointer is not moving over it smoothly. Hope it can be fixed soon? Is the general recommendation to roll-back to Nouveau? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers-331 in Ubuntu. https://bugs.launchpad.net/bugs/1408567 Title: External monitor is not working well with nvidia-331 driver in extended mode on 14.04.1 Status in HWE Next Project: Triaged Status in nvidia-graphics-drivers-331 package in Ubuntu: New Status in xserver-xorg-video-intel package in Ubuntu: New Bug description: CID: 201307-14038 Dell Vostro 5470 With the proprietary nvidia-331 (331.113-0ubuntu0.0.4 ) driver installed, the external monitor does not work as expected in extended mode.
