Priyantha Bleeker, as per your forum post, NVIDIA advised to update the BIOS, and another user advised that updating the driver to 375.66 worked for them.
Could you please advise on your BIOS version, and if testing a NVIDIA driver later than the last one you tested (346) works? ** Package changed: nvidia-graphics-drivers-375 (Ubuntu) => nvidia- graphics-drivers-346 (Ubuntu) ** Changed in: nvidia-graphics-drivers-346 (Ubuntu) Importance: Undecided => Low ** Changed in: nvidia-graphics-drivers-346 (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1281019 Title: 10de:0dda [HP EliteBook 8560w] Brightness controls are not working nvidia-319 and nvidia-331 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-346/+bug/1281019/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
