Ubuntu 12.04 GeForce GT 640 with 4 video outputs: 1xVGA, 2xDVI, 1xHDMI Have 3 connected LCDs: 2 identical - via DVIs, and one different - via 1xVGA. Video drivers: 304.116 In KDE settings all refresh rates are set to the same 60Hz (But monitors' OSD report more precise values 59.xxx) Tearing happens on both DVI-connected LCD's and does not happen on VGA- connected one. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers in Ubuntu. https://bugs.launchpad.net/bugs/423940 Title: Vsync not working with nvidia & dual monitors Status in “nvidia-graphics-drivers” package in Ubuntu: Confirmed Bug description: Using a twinview setup, vsync will not work on one of the monitors - the same one, regardless of which one the display is set to sync to. Both monitors have the same refresh rate - 60 Hz - and the same vertical resolution. Using the restricted 185 drivers, installed from the "hardware drivers" screen. Sync to vblank turned on in both nvidia-settings and compizconfig settings manager. The vsync problem also occurs if compiz is disabled entirely. This happened on a fresh install of Karmic alpha 5.
