--- Comment #23 from m11.1l1.f64@gmail.com --- There's a workaround here

I hope it helps :)

simply write this into `/etc/systemd/system/backlight-fix.service`:

``` [Unit] Description=Dummy service for attempting to start the problematic amdgpu_bl0 service

[Service] Type=simple ExecStart=systemctl start systemd-backlight@backlight:amdgpu_bl0

[Install] WantedBy=multi-user.target ```

And then `sudo systemctl enable --now backlight-fix.service`

Bingo!!

The problem is gone
