Additional regression testing: Booted Linux 7.0.0-28-generic → brightness keys and KDE brightness slider do not change the LCD backlight. Writing to /sys/class/backlight/intel_backlight/brightness changes both brightness and actual_brightness, but the physical display brightness does not change. Rebooted into 7.0.0-27-generic on the same installation. Brightness keys, KDE brightness slider, and hardware backlight all work normally. This appears to be a regression introduced between 7.0.0-27 and 7.0.0-28.
