I have encountered a strange problem. Not sure how it happened, but it was after updating the system a few days ago. No error messages per se, just the odd behavior from the system/window manager.
So, the problem is that I can not move any windows. Some times I can not write anything (for example in terminal), but other times I can. I keep loosing background images, and right-clicking does not seem to work on any windows.
I may have done things worse by trying to systemctl disable lightdm.something in an attempt to turn it ‘on/off’, but that seemed to remove something from the system, and that was not my intention.
I have switched between different wm’s, but they all have the same problems.
Any way to reinstall or ‘debug’ what is going on here? Any help is very welcome 
Goto terminal mode (console mode) at boot. Generally CTL-ALT-F2 will get you there if you don’t see it after booting.
Login.
Try to reinstall lightdm and enable lightdm.service
sudo pacman -S lightdm
sudo systemctl enable lightdm

Thank you very much for your response!
So I tried this; and got a sort of error message saying it was sym linked to something like lxdm … so it further said it was disabled, and I guess some of the problem is here? I tried to use systemctl to enable lxdm.service, and it did that without any messages back. Not sure if I do things worse again here?
Small update: I tried removing everything that had to do with xfce stuff, and that actually helped. I can now move, resize and activate windows again! So big step forward …
So I am still stuck with a problem. There might be some others too, but this is the main one I think:
- When I right-click on my desktop, it says ‘settings, change background and monitor settings’, but none of them do anything … (nothing happens when I click either). Anything I can do to fix that?
looks like a multidesktop installs system ?
If so may consider reinstalling and keep it cleaner by only use one at the time.
