There is a newer driver release by Nvidia: http://www.nvidia.com/object /linux-display-amd64-195.36.24.html
I have installed it and it changed nothing here. If that do not do it you should try http://www.nvidia.com/object/linux-display- amd64-256.25.html - the latest beta. Then, if it still wrong, Nvidia have to be informed to fix it or a workaround may be looked for. -- Backlight controls of laptops with NVIDIA NVS and Quadro FX 880M GPUs no longer function while using proprietary drivers https://bugs.launchpad.net/bugs/562005 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
