Radeon Treiber Backlight Problem

Beitrag von BongoFury » 04.04.2018 16:07:33

Hallo,
Ich hoffe das ist nun mein (vor)letztes Problem mit dem "neuen" Laptop, wobei ich eher glaube das es kein großes ist.

Beim booten bekomme ich die Fehlermeldung das das Backlight nicht geladen werden kann. Ich kann jedoch die Helligkeit regeln und sie ist auch nach einem Neustart noch so wie ich es eingestellt habe. Daher vermute ich diesen Fehler:

There are two backlight services -- one for your graphics card and the fallback acpi_video0 service.

In this case your graphics card provides the neccessary service and so the fallback fails.

You can safely mask this service to get rid of the error message:

Code: Select all
# systemctl mask systemd-backlight@backlight:acpi_vide0.service
Ich bin mir jetzt nicht sicher das so zu machen und weiß jetzt auch nicht wie ich diese Maskierung im Zweifelsfalle rückgängig machen kann wenn es nicht die Lösung ist. Daher hier nochmal meine Nachfrage.
