Screendimmer not functioning after EOS update

Hi,

I’m running GalileoNeo and I had installed one of the hardened kernels. EOS performed a system update and then screendimmer ceased to function. The tray icon still works but when you try to adjust brightness nothing happens now.

Any help is appreciated.

Hi @texitdotpro ,
Having installed hardened kernel, updated the system
sudo chmod 646 /sys/class/backlight/intel_backlight/brightness
assign Alt+F11 shortcut to this bash script:

#!/bin/bash
maxbr=21333
actbr=$(</sys/class/backlight/intel_backlight/brightness)
delta=$(( $maxbr / 10))
setbr=$(( $actbr - $delta ))
echo $setbr | tee /sys/class/backlight/intel_backlight/brightness

Similar to Alt+F12 with + delta
This is a rough test. Refine it as you like.
