Thats strange, before this issue began I had my nvidia driver installed. I’ve had a look at it and it seems I do have a driver still, I think.
[manjaro /]# mhwd -li
> Installed PCI configs:
--------------------------------------------------------------------------------
NAME VERSION FREEDRIVER TYPE
--------------------------------------------------------------------------------
video-nvidia-450xx 2019.10.25 false PCI
video-linux 2018.05.04 true PCI
Warning: No installed USB configs!
Also I’ve found some entries in journal that look like they may be connected to my problem.

I don’t know enough to say if the above are capable of hanging the system during boot up. I had a very quick read up on this freedesktop.home1.service not found and it seems to be due to broken symbolic links? I’ll look into this some more tomorrow.
