A fix.

Create the following file:

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

Add the following lines...

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

Then reboot.

Now xfce4-power-manager is able to consistently control my display's brightness.

Display Brightness with SliM and JWM

dummy@example.com (jay00) — Wed, 16 Sep 2020 20:21:39 +0000

So I am using JWM (Joe's Window Manager) with SLiM as my login manager.

After booting and then logging in Xfce4-power-manager can adjust the screen's brightness.

If I log out and then log back in Xfce4-power-manager cannot adjust the brightness for some reason.

This does not happen when using LXDM or XDM. Only with SLiM.

How can I make Xfce4-power-manager handle the display's brightness after I log out and log in again?
