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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/423940 Title: Vsync not working with nvidia & dual monitors To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers/+bug/423940/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
