I greet everyone and ask for help.
For my laptop, the norm does not work the way I want. Before Neon used Mint 18.2. There was a problem with backlight control, it was solved like this:

Code: Select all

/usr/share/X11/xorg.conf.d/20-intel.conf

Section "Device"
        Identifier  "card0"
        Driver      "intel"
        Option      "Backlight"  "intel_backlight"
        BusID       "PCI:0:2:0"
EndSection


To my regret, this method did not work in Neon. Maybe I'm doing something wrong?
