Public bug reported:
I could control the brightness of my laptop screen using hotkeys (Fn+Home/End),
although the panel applet never worked (dont know why).
Sometime ago, the brightness control using the hotkeys also stopped working.
sudo dmidecode -s system-manufacturer
LG Electronics
sudo dmidecode -s system-product-name
E200-A.CP20P
sudo dmidecode -s system-version
0100
I know they are being detected, because I did a tail -f /var/log/acpi I
this is what I got when I press one of them:
