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.
