I installed acpid, and started it

   $ sudo systemctl start apcid

confirm:

   $ jcnl -n 50

   Hmm. So the keystrokes are seen with acpid running, but it has no effect on 
the brightness. So it looks like we need to create hooks or a config for the 
events. But where? /etc/acpi/events? This is the first time with any openSuSE 
distro I've had to manually connect acpid event with screen brightness. If I 
need to create a config somewhere else, please let me know, if not, I'll go look 
at the events file. Thanks.
