When entering session and tapping the key “decrease brightness”, it decreases the brightness to the minimum level and then I must adjust it upwards. It only happens at first time on session using this button; after, not.
I don’t know if this is a Gnome’s or Manjaro’s issue, so I’m asking here because I didn’t find out where to report it for Gnome.
