After starting the system, this message is displayed on a LENOVO T14s (AMD, 1st. Gen):
$ systemctl --failed
UNIT LOAD ACTIVE SUB DESCRIPTION
ā systemd-backlight@backlight:acpi_video0.service loaded failed failed Load/Save Screen Backlight Brightness of backlight:acpi_video0
From Arch-Wiki I tried adding acpi_backlight=
into in /etc/default grub:
- Added
acpi_backlight=vendor
: Brightness always minimum (ref. here), - Added
acpi_backlight=video
: Brightness always maximum.
How to get rid of that message?
