[Solved] Login Screen Dim on Boot-Up

I was having a problem with my new Arch Enlightenment 18 install using the SLiM login manager on my Lenovo X220. The login screen was dim, but once logged in, the screen was normal brightness. I don't think SLiM itself was causing the dim login screen, but I found the solution!

# systemctl mask systemd-backlight@acpi_video0.service

Actually I stopped the service first, then disabled it, then masked it, however It was the masking of the systemd service that was required.

Found tip from following thread.
