Solus doesn't remember the brightness level I set after a reboot.
Huawei Matebook D 14 AMD Ryzen 5 3500u with integrated Vega 8 GPU.
This is the problem I suppose:
systemctl list-units | grep backlight
sys-devices-pci0000:00-0000:00:08.1-0000:03:00.0-backlight-amdgpu_bl0.device loaded active plugged /sys/devices/pci0000:00/0000:00:08.1/0000:03:00.0/backlight/amdgpu_bl0

system-systemd\x2dbacklight.slice loaded active active system-systemd\x2dbacklight.slice
Here is the relevant journalctl log:
sudo journalctl -b -u systemd-backlight@backlight:amdgpu_bl0.service
