Package: systemd
Version: 229-5
Right after start I saw on tty1:
[FAILED] Failed to start Load/Save Screen Backlight Brightness of
backlight:acpi_video0.
See 'systemctl status systemd-backlight@backlight:acpi_video0.service'
for details.
So let us see the output of the aforementioned command:
● systemd-backlight@backlight:acpi_video0.service - Load/Save Screen

Any bug fix?
