I have a MSI laptop with AMD Ryzen cpu and whenever I change the brightness using hardware keys, the video bus starts sending random brightness up/down events at random intervals.I was able to ignore these events by adding this entry in config/10-quirks.conf:
Section "InputClass" Identifier "Spooky Ghosts" MatchProduct "Video Bus" Option "Ignore" "on" EndSection but now I'm on wayland and this doesn't work anymore but on kernel 5.11+ we can inhibit input devices by putting 1 in inhibited file of the input device
for me its /sys/devices/LNXSYSTM:00/LNXSYBUS:00/PNP0A08:00/device:14/LNXVIDEO:00/input/input6/
I want this to happen automatically
I tried doing this using udev rules but it's not working
udevadm info:
