| Title makes it sound like you won't be able to run KDE Plasma on *BSD or minimal/obscure Linux distros, so I feel like it's worth quoting the bottom of the post for completeness sake: > To avoid any confusion, it’s important to emphasize that the lack of PLM support on systemd-free Linux distributions or BSD systems does not mean you can’t use the KDE Plasma desktop environment there. Plasma itself remains fully usable on those platforms. > In other words, for those users, the situation remains unchanged. On their systems, Plasma will continue to rely on SDDM or other platform-specific startup mechanisms, with no indication from KDE that PLM will be made portable beyond systemd environments. |

| ▲ | pseudalopex 22 minutes ago | parent | next [-] | | Plasma Login Manager was how the KDE developers planned to support remote Wayland sessions. And they will remove X11 sessions. Someone will have to add VNC and RDP to SDDM? Or is there another way? | |
| ▲ | graemep 2 hours ago | parent | prev [-] | | However it does look as though KDE will depend on systemd more in the future. In which case it will gradually drop support for BSDs and Linux distros without systemd. | | |
| ▲ | ahartmetz an hour ago | parent | next [-] | | Unlikely, KDE has well-respected developers who have been around forever who run and maintain it on BSD. No one would tell these guys to pound sand for the minor convenience that systemd brings. IMO, KDE developers (I'm a mostly inactive one myself) are generally too eager to rely systemd, but they aren't extremist about it. | | |
| ▲ | mghackerlady an hour ago | parent [-] | | I don't oppose leaning on systemd for small non essential things like this, especially if there's an easy replacement for non systemd systems |
| |
| ▲ | jmclnx an hour ago | parent | prev [-] | | FWIW, I tend to think eventually everything will. But I am more worried about Wayland than systemd for the *BSDs. AFAIK, all systemd does is start items KDE needs, so with some work I think workarounds can be created. But, once Firefox changes to Wayland only, that will lock out NetBSD and OpenBSD. I heard FreeBSD has some kind of support for Wayland, but that probably forced FreeBSD to import a lot of Linuxisms. I get the impression OpenBSD will not bring in those Linux specific items and NetBSD already posted Wayland is to big a project for them to import at this point. | | |
| ▲ | ahartmetz 43 minutes ago | parent | next [-] | | Wayland needs... I think some EGL stuff to create OpenGL or Vulkan contexts in Wayland apps and a kernel API for graphics modesetting (resolution and refresh rate + misc related stuff). Also input support in libinput. Modesetting is perhaps the biggest piece of work, but I dare say not a huge one compared to having drivers for modern GPUs in the first place. What's going to suck is that every major compositor +wlroots for the non-major ones is also going to need patches to use the BSD modesetting API - something that the BSD guys don't have direct control over and which is maybe a little out of their traditionalist(?) comfort zone. Or are the BSDs simply going for a copy of the Linux KMS (kernel modesetting) API? Wouldn't be the worst idea, Linux finally seems to have something robust there after earlier attempts that were considered problematic. | |
| ▲ | mghackerlady 44 minutes ago | parent | prev | next [-] | | FreeBSDs Wayland support is pretty good, it supports Plasma perfectly and most wlroots based compositors. OpenBSD is more experimental, I know Sway (and presumably other simple wlroots based compositors) work alright but I wouldn't hold my breath for KDE support. I haven't heard anything from NetBSD or DragonflyBSD | |
| ▲ | JohnFen an hour ago | parent | prev [-] | | I agree, Wayland is a much larger problem. |

| Graphical login managers are just a nightmare altogether. Genuine use cases for multiuser desktop Linux are exceedingly rare. (Are university computer labs with desktop computers still a thing? Or is it just Wi-Fi and BYOD now?) On an effectively-single-user system, there is very little point in distinguishing between the state where the single user has logged in and the session has been locked versus the state where the single user has not yet logged in. Dealing with the discontinuities between those two states, on the other hand, is a nightmare. (e.g. Wi-Fi might be controlled through the desktop session. Why should the computer not be connected to Wi-Fi and its network services reachable, just because the user hasn't logged in yet? What about power management? If the single user has turned off the feature to automatically suspend after x minutes of inactivity through KDE settings, why should that setting only start to apply after the user has logged in, and not yet when the greeter is still sitting idle? Those kinds of behaviours are usually not what you want) -- And, subjectively, I've found the KDE login manager to be the buggiest part of my KDE experience anyway. I would advise anyone to set up auto login with something like sddm, and skip the whole thing. Password entry is a bit redundant, assuming the user has already entered at least one password for disk encryption, and things like ssh are governed through key pairs. |

They'd be happy to hand those out to the poor and needy who, however, wouldn't be caught dead with one of those. Because, sporting the latest iPhone at all times is part of the reason they're poor. -- The world is a complicated place, man. | |

| Can KDE function without it, using e.g. lightdm? If so, not a big deal. |

| ▲ | nargek 2 hours ago | parent | next [-] | | > We are not sure where you folks are getting your info, but it is dead wrong. > FreeBSD users will still be able to boot into Plasma with any other login manager that works on FreeBSD, including SDDM, which is upstream from Plasma anyway. > Linux users will just have one more option. > Plasma has no hard systemd dependencies. cf. https://floss.social/@kde/115933236466022060 | |
| ▲ | arusahni 2 hours ago | parent | prev | next [-] | | Yes. You can also continue to use SDDM. | |
| ▲ | mghackerlady 42 minutes ago | parent | prev | next [-] | | SDDM will keep working, and KDE maintains a LightDM greeter. You don't even need to use a login manager, most people in the BSD space launch it from the tty | |

| Can someone explain why SystemD was controversial in the first place? I just saw faster boot times when distros adopted it. |
| |
| ▲ | Sharlin an hour ago | parent | next [-] | | Scope creep, violation of the Unix philosophy, large attack surface area, second system syndrome, interoperability concerns. It didn’t help that the creator’s other well-known project, PulseAudio, was also controversial at the time, for similar reasons. | | |
| ▲ | BearOso an hour ago | parent [-] | | PulseAudio, when it came out, was utterly broken. It was clearly written by someone with little experience in
low-latency audio, and it was as if the only use case was bluetooth music streaming and nothing else. Systemd being from the same author made me heavily averse to it. However, unlike PulseAudio, I've encountered few problems with systemd technically. I certainly dislike the scope creep and appreciate there are ideological differences and portability problems, but at least it works. |

| ▲ | noirscape an hour ago | parent | prev | next [-] | | Wrote about present day reasons to dislike systemd a few days ago on HN, which encompasses most arguments of actual substance[0] (tldr: Unix philosophy, it homogenizes distros and it may be too heavy for some low-resource environments). Historic reasons mostly come down to systemds developers being abrasive jerks to people. Systemd has some weird behavior choices that only really make sense from the perspective where every computer is a desktop; ie. it terminates all processes spawned by a user when logging out unless they were made in a specific way with systemd-run. This makes sense on a desktop - users log out, you want everything they did to be cleaned up. On a server it makes less sense, since you probably want a tmux/screen session to keep running when you sign out of your ssh session (either by choice as a monitoring tool, or alternatively because you have an unstable connection and need a persistent shell). Every downstream distro got surprised by this change[1] and nowadays just ships a default configuration that turns it off, because upstream systemd developers weren't interested in hearing the complaints. Most of these footguns have been ironed out over the years though. There's also some really dumb arguments to dislike systemd, most of which just can be summarized as "people have an axe to grind with Lennart Poettering for some reason". [0]: https://news.ycombinator.com/item?id=46794562 [1]: It was always available, but suddenly turned on by default in an update. | |
| ▲ | neoCrimeLabs an hour ago | parent | prev [-] | | To over-simplify, it's about conflicting philosophical alignment: - systemd: integration and features at the cost of complexity and scope - traditional: simplicity and composability at the cost of boot speed and convenience systemd conflicts against the more traditional unix philosophies as well as minimalism. | | |
| ▲ | ahartmetz 33 minutes ago | parent [-] | | systemd also replaces some pre-existing services with its own reimplementations that are worse. The systemd developers aren't e.g. DNS or NTP experts, but they act like it and the results reflect all that. |

| I worked on both Linux login process, SDDM and LightDM in the past. The process is complex to put it mildly. While PAM is a relatively straightforward system, interfacing with it and handling what it says is a bit backwards and complex (e.g.: Try to handle and relay LDAP password policy warnings to the user while in the login screen, and you'll have a fun time). While I don't like systemd, I can understand why KDE devs want to integrate with it, esp. if doing so simplifies their life and reduces the number of edge cases. Also, last but not the least, a KDE session is a complex beast. KDE overrides almost half of the environment it inherits to realize what the user has requested via System Settings (locales, esp.). So this is why I don't condone, but understand what they did. ...and yes, as everyone said, KDE will work with any login manager. |

| ▲ | busterarm an hour ago | parent [-] | | PAM is indeed a minefield. A while back I lost a system because I had it configured with full disk encryption and pam_usb for totp-enhanced logins. A bugged update that I applied via pacman broke PAM and I lost my ability to login. This would have been just annoying and not catastrophic had I not also had FDE and forgotten where I stored my LUKS key. Lesson learned. | | |
| ▲ | bayindirh an hour ago | parent [-] | | > PAM is indeed a minefield. I'd not label it such, but as "critical infrastructure". The problem in your case actually was not in PAM but in pacman. For example, apt and yum/dnf checks whether the checksum of the file being changed is different from the original (provided by the package). In standard configuration, apt asks what to do, dnf just puts the file with .rpmnew extension to prevent these kinds of problems. pacman's "I don't care, this is the new file and I overwrite what I see" is very dangerous behavior. | | |

| It's worth noting that all of this drama stems from the (somewhat opaque, to put it nicely) reddit comments of one KDE developer, so that warrants treating it as a rumor in my book. It would be prudent to wait for an announcement or clarification from KDE leadership before assuming anything one way or the other. |
| |
| ▲ | pseudalopex 5 minutes ago | parent [-] | | The Reddit thread had comments of 2 KDE developers and a link to the merged merge request removing FreeBSD support. |

| I hope there can be ways to circumvent this limitation and make it usable on non-systemd installs, i.e. with elogind (systemd's "logind extracted out to be a standalone daemon") https://github.com/elogind/elogind |

| Gentoo already has elogind which mimics the necessary systemd facilities... surely that could be used on other distros/OSes to support PLM as well. |

| Sounds like a dependency. Not a particularly new issue in software. |
| |
| ▲ | v3ss0n 2 hours ago | parent | next [-] | | Yeah, if you want initd support work it on your own , its opensource anyways (and initd is too basic to do any of those advanced features of systemd) | | |
| ▲ | hnlmorg 2 hours ago | parent [-] | | …or just continue to use SDDM like before. It’s a new piece of software that’s tied to systemd. Existing software is unchanged. |
| |
| ▲ | _fizz_buzz_ an hour ago | parent | prev [-] | | Are there still a lot Linux distros that don't use systemd? |
|
|
| ▲ | hnlmorg 2 hours ago | parent | prev | next [-] |
| tl;dr: this is a new login manager. Nothing is changing for existing login managers. So you can continue to use KDE Plasma on alternative init daemons / non-Linux OSs like before. |

| KDE's decision to move toward only supporting systemD systems is a real loss and saddens me. KDE has been my favorite DE for years. I guess all good things come to an end, though. |
| |
| ▲ | hnlmorg 2 hours ago | parent | next [-] | | They’re not. This is one new and entirely optional login manager. Nothing that is already available is changing | | |
| ▲ | philipallstar an hour ago | parent [-] | | As one frog said to the other frog: it's only a couple of degrees warmer! What's the problem? | | |
| ▲ | hnlmorg 3 minutes ago | parent | next [-] | | Again, this is a new piece of software. It does not affect existing login managers (eg SDDM) and nor does it affect KDE Plasma itself. The approach the KDE team took here is 100% the correct approach and, crucially, does not affect Plasma’s cross platform support at all. This whole thing has been blown out of proportion by armchair critics commenting with made up hypotheticals without any of them reading what the actual change was. It’s ridiculous | |
| ▲ | ahartmetz 27 minutes ago | parent | prev [-] | | It's a minor temperature increase, but I believe that KDE quite explicitly does not intend to boil that frog. |
|
| |
| ▲ | jeroenhd 2 hours ago | parent | prev | next [-] | | No, Plasma Login Manager relies on systemd. SDDM and any other login manager doesn't. You can still use KDE. | | |
| ▲ | JohnFen 2 hours ago | parent | next [-] | | For now, but the writing on the wall seems clear. > The focus of the KDE team is clear, as stated in the referenced Reddit thread, where a KDE developer replies that the goal is to rely on systemd for more tasks in the future. This means that PLM is just the first step. https://hackaday.com/2026/02/02/kde-binds-itself-tightly-to-... | | |
| ▲ | bri3d an hour ago | parent [-] | | Hackaday, and you, omit the last sentence in the comment they quote: “The compromise is going all in contained areas where alternatives exist.” | | |
| ▲ | JohnFen an hour ago | parent [-] | | I hope that's true, and remains true. I mean, this is not exactly the most important issue in the world. I love KDE and hope it remains usable to me, but if things keep going as a fear, there are other DEs that I can live with. |
