@Ed I know /etc/systemd/system/display-manager.service is a symlink, I
use zsh so I saw the light blue flashing text in my terminal ;)
And neither works meaning, I tried replacing this symlink with one
pointing to /usr/lib/systemd/system/sddm.service
because the command you gave me would not overwrite the symlink.. and I
even ran it as root but it still refused. No clue why really but honestly I
didnt care enough to find out. So I manually created a new symlink to teh
sddm file. Then later on I created one (overwriting the default) to the
LightDM service file. All to no avail.
And by boot correctly in last nights escapades I mean that this time... I
did not even get a mouse cursor... just black.
And I did remove the Gnome bits but this time I did it individually after
'sudo --exclude='qemu* libvirt*' remove gnome-<package-name>' which
after
many of these the GDM was removed, I ended up reinstalling GDM* which in
turn reinstalled every BLASTED thing that I had just removed beforehand.
So frustrating.
I did check the contents of /var/lib/sddm/state.conf and it references
gnome-desktop of all things! Why is it so bloody hard to change the
Display Managers up in here??
@Joe So are you meaning that I should mask or delete the symlink to my
current DM, maybe reboot then create one for teh other.. like SDDM or
LightDM?
So tonight, I guess I should try again.. maybe remove and reinstall sddm
and I'd firstly think that installing a few other DM's would be a good idea
but then I'm left with so many other dependencies that I'd be in the same
boat as now. So am I correct in thinking that reinstalling sddm, I will
retry the enable command and see if the results are different this time..
and if greeted with a black screen then journalctl should be my friend.. Oh
and also check that state.conf file to make sure it's not still pointing to
GDM... Is this a solid plan?
