Plasma Workspaces 2 Coming To Wayland, KDM Not Invited

Auf Wiedersehen KDM

The first part of today’s headline is probably obvious to many of you.  KDE will be moving on from Xorg to Wayland.  And considering Gnome’s aggressive plans to move to it, this may happen sooner rather than later.  KDE & Gnome having a mutual interest in Wayland is great, and we can’t wait to reap the benefits of it.  But it seems that one technology — one that’s synonymous with KDE — will likely not be making the transition.

In a delightfully composed blog post by KDE’s Aaron Seigo, we learned of a late night meeting to determine the fate of KDM, the requirements of it’s replacement, and the overall future of login mechanisms for KDE.  The requirements are as follows.

  • Must be lightweight. We want to use this on desktops and devices.
  • Must be maintainable. (Self explanatory.)
  • Must be able to write the user interface in QML.
  • Must be able to be a Wayland system compositor.

In what came off as a dating show satire, Aaron had these words to say about KDM:

This contestant is a deep soul with much complexity who likes things the old-fashioned way. 20 year old scotch is its drink of choice, and it hates walks on the beach (not much of a romantic, you see). It holds advanced degrees in many traditional practices. Let’s say hello to .. KDM!

While at first KDM was revealed as a contender, its fate was revealed later in the post:

This is a difficult decision to make. KDM is not going to make the transition into a QML and Wayland world with us, despite it having served us well in the past. We need something to take its place, and we’d prefer not to start from scratch when there are good choices that already exist.

So it looks like the competition for KDM’s successor is a one-on-one duel between lightDM and SDDM.  Let’s not place any bets just yet, but if you’re using Kubuntu, you may already be accustomed to LightDM which seems to work amicably   But will it work well across every type of device that Plasma Workspaces 2 wishes to target?

SDDM

    That screenshot of LightDM looks extremely ugly.

    I don’t care what I use to login to my desktop – just give me a theme that doesnt make my computer look like it was build in the 90s. Also overuse of gradients, shadows, and overly rounded edges aren’t my thing.

    GDM 3.8 is looking good these days.

    SDDM looks nice, clean, professional, not full of 90’s style rounded corners like some playschool toy….I’m an adult, I don’t mind sharp corners :)

    One of the advantages of QML is that we can make it look however we wish. The look is not important in this decision, but rather the underlying code that drives the display manager. We will certainly ship a sensible default QML theme for whatever DM we eventually select. :)

    I hope Mir is also supported to KDM/Plasma

      According to the KDE devs, not likely. This is probably because it’d mean doubling to tripling the complexity of KDE to support a window system that is frankly doomed from the get go. Mir’s a dead end because few things Canonical develops for Ubuntu port well to other distributions.

    Have to admit, I like LightDM’s look. I never cared for the click on a user and enter a password style. I like it so you have to enter two forms of ID so to speak instead of just one. Makes it more guesswork for someone who’s trying to mess around with a machine.

    This article portrays LightDM in a bad light in relation to SDDM. I’ve seen some gorgeous LightDM themes, but the Kubuntu one is not one of them (like the distro itself, which I find rather bland).

    Anyway, exciting to see the work on KDE 5 progress. Though it will be an evolution rather than a revolution, that is probably a good thing. It’s good to see the developers migrating to a more stable and easily-maintainable stack too, where less of the issues currently faced by them will be present.

    I see absolutely nothing in the source article that says they’re ditching Xorg in KDE. In fact, the KDE developers would have to be absolutely stupid to drop support for a mature windowing environment for a still-unproven library dependent on something that only supports open drivers. All I get from this is they’re smart enough not to make KDE a Mir-based desktop.
