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.
