How to set permanent file write permissions for /sys/class/backlight/backlight/bl_power
in order to allow user (not root) to power on/off the display?
User has no permissions and sudo is not available?
Is there a possibility to set file permissions upon boot (i.e. chmod g+w /sys/class/backlight/backlight/bl_power) in order to make them ‘permanent’?
Thanks for feedback.
