It would be great if the developers from NVIDIA would give this show-stopping bug a high-priority for their first next driver release.

Not to my knowledge: that changelog entry refers to adding an additional interface via the NV-CONTROL API to the existing backlight functionality. The problem is that the existing backlight functionality is now broken on some laptops, so it doesn't make a difference whether it's exposed through a new API or not. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1241745 Title: [regression] Changing the screen brightness does not work anymore in 319.xx To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1241745/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1241745] Re: [regression] Changing the screen brightness does not work anymore in 319.xx
Sorry, at the moment we don't have an ETA for a fix. It's not likely to be fixed in the immediate future. I've added a note to the bug report on the NVIDIA bug tracker as a reminder to update this Launchpad thread when we have a fix in hand. The only workaround I'm currently aware of is to use an older driver, but older drivers may not be compatible with newer X servers and kernels. The 304.xx series is maintained as a legacy branch, so it would be compatible with newer kernel / X server versions, and unless your hardware is especially new, there's a good chance that a 304.xx driver will work for you. The recently released 304.116 driver, for example, is compatible with Xorg up to 1.14 and Linux up to 3.12. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1241745 Title: [regression] Changing the screen brightness does not work anymore in 319.xx To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1241745/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
