Unable to change brightness using xbacklight

Even though i added video group to my user account, it still shows permission denied
but it works when using with sudo

xbacklight -inc 10

/usr/bin/xbacklight: [Errno 13] Permission denied: '/sys/class/backlight/intel_backlight/brightness'


sys network power video lp wheel autologin n02m399

edit: solved by rebooting

Please reply to your own post stating the solution and then mark it as such.


And also remove the [Solved] tag from the thread’s title. It’s unnecessary. :slightly_smiling_face:
