Screen brightness & GDM background

[Alternity]

When I startup my laptop, before showing the desktop it says:

[FAILED] Failed to start Load/Save Brightness of backlight:acpi_video0.
[FAILED] Failed to start Load/Save Backlight Brightness of backlight:amdgpu_b10.

And my screen brightness is reset to 0 when the computer starts up.

Also, on the Gnome login screen, I have a grey background, instead of the wallpaper I chose for the login screen.

Can anyone help?

Thank you

I have trid other possible solutions, including modifying the file 10_manjaro-gdm-branding at /etc/dconf/db/gdm.d and gnome-classic.css at /usr/share/gnome-shell/theme, but neither of them works.
