I don't know if this is relevant, but back on an older version of Ubuntu, the keys weren't working either and I to work around this I had set up two scripts that I had bound to the F1 and F2 keys, and they basically did the same thing: Incremented or decremented the contents of the brightness pseudo-file. However, the file path was /sys/class/backlight/mbp_backlight/brightness, not /sys/class/backlight/nvidia_backlight/brightness. I do not have a /sys/class/backlight/mbp_backlight/brightness file any more now. -- nvidia-bl-dkms 0.15.1 update breaks backlight https://bugs.launchpad.net/bugs/516354 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
