Inverted brightness button
0
I use the last Ubuntu version (18.10) on my laptop (Compaq 15-s020nf) and the brightness button are inverted.
I got the same behavior when I control the backlight with the command line:
echo 1000 > /sys/class/backlight/intel_backlight/brightness # I got a bright screen
echo 6000 > /sys/class/backlight/intel_backlight/brightness # I got a dark screen
Do you have any advice to resolve that ?

I dont have a solution, but do your volume up/down buttons work correctly? You could look into acpi settings, I know I had some issues with the brightness settings when messing with it. Other than that check out some bug reports, I know of some people that had the same issues in past Ubuntu version.
