Based off of the ArchlinuxTop lxdm theme with just a few minor changes.
After you unzip it, move it to your
/usr/share/lxdm/themes/
directory.
Make sure in
/etc/lxdm/lxdm.conf
that theme is set to ArtixTop
Any advantages and disadvantages of LXDM to SDDM?
Would people running LXDE or openbox benefit from LXDM being a more native DM than others?
Eh not really, the only one that comes to mind is that SDDM integrates with KDE, but beyond that you can use them interchangeably. Granted, I've never use LXDE or Openbox; I would imagine that LXDM integrates with LXDE (or LXQT as well?)
