Comment 13 for bug 1686268

The exact command you wrote:

$ systemctl status systemd-backlight@intel_backlight.service
systemd-backlight@intel_backlight.service - Load/Save Screen Backlight Brightness of intel_backlight
   Loaded: loaded (/lib/systemd/system/systemd-backlight@.service; static; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:systemd-backlight@.service(8)

However the following one (with an added "backlight:") gives a different answer:

$ systemctl status systemd-backlight@backlight:intel_backlight.service
systemd-backlight@backlight:intel_backlight.service - Load/Save Screen Backlight Brightness of backlight:intel_backlight
   Loaded: loaded (/lib/systemd/system/systemd-backlight@.service; static; vendor preset: enabled)
