    Default sddm login theme

    Since KDE4 i used to have my "personal" kdm login theme. With openSUSE 42.1 came sddm and my beloved theme didn't work any longer.

    I do know little (not to say nothing) about QT or QT programming so i consulted the themes provided by the sddm package and finally managed to port my kdm theme to sddm successfully. So far, so good. But there is one thing i couldn't figure out yet:

    I want to have the current kernel version being displayed on the login screen. sddm does not seem to provide a property for it (at least i didn't find one). Some way down the internet i found something like QSysInfo::kernelVersion but have no idea how to use it my Main.qml.

    Is there anybody out there who could advice me on how to proceed?

    Thank you very much in advance.

    Best regards

    Well, I don't know an answer to your question, but kdm is still available and usable in Leap 42.1...
    You don't *have* to switch to SDDM.

    Thank you very much for your quick response.

    My openSUSE 42.1 (KDE Plasma Version 5.4.3) runs quite smooth at the moment but there are still some "strange features" that i can't really explain (like my desktop gets stuck as soon as i switch my windows decoration to "Plastic").

    Can i switch to kdm without running into more "strange features"?

    Best regards

    Yes, I heard about problems with "Plastik" (not only from you IIRC), but I cannot reproduce them here (on 13.2).

    Yes.
    kdm/sddm is just the login screen. It doesn't affect the user session at all.
    And you can of course always switch back if you would experience problems.

    You can have more than one DM installed, and (actually have to) switch between them via /etc/sysconfig/displaymanager (e.g. DISPLAYMANAGER="kdm").

    Same here: With openSUSE 13.2 (KDE4) "Plastik" doesn't cause problems on any of my machines. But with Plasma5 "Plastik" causes trouble. With NVIDIA graphics (nouveau) as well as with INTEL graphics even with compositor disabled.

    I wasn't aware of that. So i might give it a try. And as you said: i can always switch back if i experience problems.
    Nevertheless i am curious on how to build a sddm login theme which displays the kernel version of the running kernel (just for education sake ).

    Sorry for not being clear enough: It doesn't cause any problems here on 13.2 with *Plasma5* (latest version from KDE:Frameworks5, so compareable to Leap, until recently at least), on two different systems (one with radeon, one with intel).

    Ah, i see, so that's different to my setups.

    I always run two versions of openSUSE on my machines: the latest and the one before. The latter - currently openSUSE 13.2 - is my "safe fallback" which i can use when there is "real work" to be done. So i would not like to install Plasma5 on openSUSE 13.2 to investigate whether "Plastik" would work in that setup or not. And - even worse - i have no idea how to further investigate the "Plastik"-problem at all.

    Best regards
