 ### Backlight
 
-**TODO 2024**
-
-```
-doas apk add light
-doas micro /etc/udev/rules.d/backlight.rules
 ```
-add the following lines into backlight.rules to make it possible for all users in video group (not just superusers) to control backlight:
-```
-ACTION=="add", SUBSYSTEM=="backlight", KERNEL=="amdgpu_bl0", RUN+="/bin/chgrp video /sys/class/backlight/%k/brightness"
-ACTION=="add", SUBSYSTEM=="backlight", KERNEL=="amdgpu_bl0", RUN+="/bin/chmod g+w /sys/class/backlight/%k/brightness"
+doas apk add enlighten
+doas rc-service udev restart
 ```
-and then
+
+and add the following lines to river config:
+
 ```
-doas rc-service udev restart
+riverctl map $mode None XF86MonBrightnessUp   spawn "BACKLIGHT_DEVICE=amdgpu_bl1 enlighten +5%"
+riverctl map $mode None XF86MonBrightnessDown spawn "BACKLIGHT_DEVICE=amdgpu_bl1 enlighten -5%"
 ```

 Backlight control with Fn+F5/F6 should work now.
 
 (`amdgpu_bl0` is specific for this laptop; value for others can be obtained from `/sys/class/backlight/`)
