I created a login screen concept using Canva. The icon for the menu is sourced for free by Canva, obviously, but that can change to an icon from Suru. I couldn’t find the original repo until after I made the image. It’s a server-based login dialog box.
Here is the concept.
I like the idea, is this intended to replace gdm3?
I suggest to switch the color of “power-off” button from green to red and maybe it will look better if words are a bit smaller. 
Yes, it is to replace GDM3. I’ll try doing the colour change and upload the update. If only there was a way to skin GDM like that.
Maybe, we should take the idea from Antergos, which uses gnome-shell with a customized login screen. 
That sounds interesting.
