Brightness control command on "startup Applications" is not working

rated 0 times [ 1] [ 0] / answers: 1 / hits: 1035 / 1 Year ago, sun, december 11, 2022, 3:17:21

On "Startup Applications" utility I added my suitable brightness to be configured each time OS is launched. But it is not working at all. I am having to bear system's very high default brightness.

the command is : xrandr --output LVDS1 --brightness 0.5

Startup Applications is very fine although. I have also added up firefox opening command which is opening it well.

This brightness command is working from terminal. How do i make it work from startup App ?
Thanks in advance.

install indicator-brightness 'bar for brightness control'

$ sudo add-apt-repository ppa:indicator-brightness/ppa

$ sudo apt-get update

$ sudo apt-get install indicator-brightness

opening

usage

or

make it start on boot

install
$ sudo apt-get install xbacklight

open the 'Startup Applications' then and add a 'new startup item' with the command:

xbacklight -set 40

40 is the brightness lvl

from 1 => 100

don't use them both
