    Default Start a Plasma 5 Wayland Session in SDDM

    How can I start a Plasma 5 Wayland session from the SDDM?
    In the drop down list I have "Plasma 5 Workspace" and "Plasma 5" as choices, but nothing about Wayland.
    I am running the latest Plasma 5.7.2 along with Frameworks 5.24 and KDE Applications 16.04.3.

    Now with Plasma 5.7, Wayland should be mature enough to use.

    Edit: Got to thinking. Could it be that because I use nvidia? Think I read somewhere that nvidia did not have Wayland ready display driver or something. I have installed Nvidia 367.35

    Oh and by the way, I have the wayland packages installed.

    Found some indications that perhaps older Nvidia graphic cards will not get support for Wayland, even if the newest proprietary driver does have support for Wayland.
    I am running my system on Nvidia GeForce GTX 650Ti.

    I have an Intel graphics chip, but ...

    I got Plasma (Wayland) in the SDDM menu after installing the plasma5-session-wayland package and a few dependencies with YaST.

    I was not enamoured with Plasma (Wayland) -- mostly because of the lack of touchpad taps and swipes, and attempting to open the touochpad configuration crashed/closed System Settings. I am currently using an offbeat install -- Leap-42.1 base with the graphical desktop (KDE Plasma) from Tumbleweed, so my experience is probably not typical.
    ~Thank you for sharing an interesting problem.

    I don't have the package plasma5-session-wayland

    Have the following KDE repositories.
    QT http://download.opensuse.org/reposit...USE_Leap_42.1/
    Plasma5/Frameworks5 http://download.opensuse.org/reposit...USE_Leap_42.1/
    Applications http://download.opensuse.org/reposit...USE_Leap_42.1/

    Plasma/Wayland and plasma5-session-wayland is not available in Leap 42.1, because the included Wayland is too old.

    If you want to use a Plasma5 Wayland session, you'd need to upgrade to Tumbleweed.

    But note that Plasma5/Wayland is very much still work in progress.

    And as you suspected yourself already, this does not work at all with the nvidia driver anyway.
    nvidia does support Wayland to some degree, but they don't do it properly. You need to patch the compositor with patches they provide.
    But they only provide those patches for Weston (Wayland's reference implementation), not Plasma5/kwin (nor GNOME).
    See http://www.phoronix.com/scan.php?pag...and-Discussion

    The best way to try it is probably download and boot an openSUSE Krypton LiveCD...
