Hi, I recently installed Manjaro and have been loving it. Unfortunately, I have been experiencing the problem that the monitor backlight of my laptop is completely deactivated after a suspend and I am forced to reboot. Thank you in advance for any tips!
What happens if you press CTRL+ALT+F2 and then CTRL+ALT+F1?
Nothing happens, unfortunately. I can, however, faintly see the login box and CTRL+ALT+DEL works. When I connect an external monitor, then I am able to log back in, but the laptop screen is still black. I have included some information below:

There seems to be an error here, but I am not sure if it is related:
[holden@holden-20h1004tus ~]$ sudo bootctl
Couldn't find EFI system partition. It is recommended to mount it to /boot or /efi.
Alternatively, use --esp-path= to specify path to mount point.
System:
Not booted with EFI
Have you tried kernel 5.4?
