Error on Bootup

Hi guys,

I have been having the same issue issued posted in a different section of these forums (Link to the post: https://bbs.archlinux.org/viewtopic.php?id=187921) however, mine is slightly different. As you can see someone suggested in his post to post the result of the command "systemctl status systemd-backlight@backlight:acpi_video0.service" his status of the backlight service, he did and when I ran the same command we had different statuses. So I am guessing that we have different solutions to the problem. My command resulted in the following:

[vrajpatel@VArch ~]$ systemctl status systemd-backlight@backlight:acpi_video0.service
● systemd-backlight@backlight:acpi_video0.service - Load/Save Screen Backlight Brightness of backlight:acpi_video0
   Loaded: loaded (/usr/lib/systemd/system/systemd-backlight@.service; static; vendor preset: disabled)
   Active: inactive (dead)
     Docs: man:systemd-backlight@.service(8)
[vrajpatel@VArch ~]$ systemctl start systemd-backlight@backlight:acpi_video0.service
Failed to start systemd-backlight@backlight:acpi_video0.service: Access denied

Please help, I want to rid this error from boot up because it is annoying and extends the boot time.

I don't see anything wrong here.
The access denied is because you can only start this service as root.

EDIT: run

systemctl --state=failed

to see which units have failed to load

Your command resulted in the following.

[vrajpatel@VArch ~]$ sudo systemctl --state=failed
  UNIT                                            LOAD   ACTIVE SUB    DESCRIPTION
● systemd-backlight@backlight:acpi_video0.service loaded failed failed Load/Save Screen Backlight Brightness of backlight:acpi_video0

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

1 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.

Also I am sure that something is wrong because before I posted this I looked through the journal using command "journalctl -xe." Here is proof:
