Afetr some updates of my system Ubuntu 16.04 LTS; the brightness is higher, I'haven't possibility to set it, It doesn't appear on power manager. I've installed xbacklight and set this configuration
xbacklight =50 xbacklight +10 xbacklight -10
After the reboot, nothing change, this dialog box prompts dialog box
That mean : Impossible to set the configuration
So I installed Indicator brightness to have to set it in the system tray, but i have this notification:
No backlights were found on your system
It returns nothing
I decided do to use laptop-mode-tools, but I can't use it because the precendent command return nothing ( no files or directories in /sys/class/backlight/)
Maybe this can help to:
lspci | grep "VGA compatible controller" 00:02.0 VGA compatible controller: Intel Corporation Haswell-ULT Integrated Graphics Controller (rev 0b)
I think I did more effort for my English level.
I need your helps to solve this problem.
My eyes are suffering actually
