I've removed the NVIDIA drivers and configured Ubuntu to use Nouveau. sudo apt-get remove --purge '^nvidia-.*' sudo apt-get install ubuntu-desktop echo 'nouveau' | sudo tee -a /etc/modules
This hasn't fixed the situation. Altering the settings does not affect the actual screen brightness (or the keyboard backlight). /sys/class/backlight/intel_backlight/actual_brightness doesn't change, although the indicators do. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1862835 Title: Unable to change laptop screen brightness or keyboard backlighting To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1862835/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
