SDDM: A Lightweight QML-Based Display Manager
Phoronix: SDDM: A Lightweight QML-Based Display Manager
A Phoronix reader has announced his work on SDDM within the Phoronix Forums this weekend. SDDM is a very lightweight display management that takes advantage of Qt's QML...
how does this compare to SLim? SLim has even fewer dependencies; X11, libjpeg, libpng, freetype.

Reason: Fixing link to SLiM
Yes but arent slim themes harder to write and get the same level of functionality in comparison to lightDM? The goal of lightdm was have a clean, modern, standardized core and then the greeter frontends could all be distro-specific with no problem. Want an update to lightdm? Rebase off mainline, slap your greeter right back on and youve got all the same benefits all the other distros do but still your branding.

What is wrong with adding the ability to use shaders? If most of us the window managers that are composited and gpu-accelerated, why shouldn't the display manager be? Why should we restrict ourselves and theme designers? Display manager is the one first things a user sees it has to be attractive, IMHO.

Because the login manager is one of the things that should never fail.

Slim themes are harder to write and somewhat restricted. In SDDM you write your theme however you want, just call the needed functions for authorization/shutdown/reboot when necessary, just like using a library. So you dont have to worry about the restrictions of the backend when designing your themes. Animations, transitions and all other stuff are bonus points.

I think a login manager should authenticate via:
* Bluetooth and NFC security tokens and smartphones
* USB sticks, dongles and security tokens
* Smart card
* LDAP and Active Directory
Things that will need to be added to LightDM if they arent already, eventually. Especially the last 2
