https://fedoraproject.org/wiki/Changes/WaylandByDefaultForSDDM = Wayland by Default for SDDM = == Summary == Change the default display server mode for SDDM to use a Wayland-based greeter rather than an X11-based one. == Owner == * Name: [[User:Ngompa|Neal Gompa]], [[User:Rdieter|Rex Dieter]], [[User:Jgrulich|Jan Grulich]] * Email: ngompa13(a)gmail.com, rdieter(a)gmail.com, jgrulich(a)redhat.com * Product: KDE Spin, Kinoite * Responsible WG: KDE SIG == Detailed Description == With [https://github.com/sddm/sddm/pull/1393 the work done upstream in SDDM to support using a Wayland based greeter] and [[Changes/ReplaceFbdevDrivers|the introduction of SimpleDRM to fix the broken fallback when platform drivers are unavailable]], it is now possible for the Fedora KDE variants (the regular spin and Kinoite) to move to Wayland for the login manager, which effectively completes the switch to Wayland for these variants. == Benefit to Fedora == As originally detailed in [[Changes/WaylandByDefaultForPlasma|the Change to switch Plasma to Wayland by default]], Fedora is a leader in advancing the adoption of the Wayland protocol as part of the overall strategy to improve the Linux graphical software stack. We have been successful in helping drive Wayland forward in the Plasma Desktop, and we intend to do the same for SDDM. == Scope == * Proposal owners: ** Upgrade {{package|sddm}} to the latest snapshot and introduce mutually exclusive <code>sddm-wayland-generic</code> and <code>sddm-x11</code> greeter configuration packages. ** Modify {{package|plasma-workspace}} to switch SDDM to Wayland *** Enable installation of the SDDM Wayland configuration snippet and ship as <code>sddm-wayland-plasma</code> that is mutually exclusive with the other sddm greeter configuration packages.

In order to override this, the user can do one of the following: * Drop in a configuration file in <code>/etc/sddm.conf.d</code> to set the display server back to X11 * Swap back to X11 with the configuration package: <code>dnf swap sddm-wayland-plasma sddm-x11</code> == How To Test == Once the SDDM and Plasma Wayland changes are made, Rawhide users can try this by using nightly KDE ISOs and using them normally to install and run a Rawhide KDE Plasma environment. == User Experience == Ideally, there should be no noticeable impact on the user experience, though users may notice that things operate more smoothly and with slightly lower resources.

If you select X11 at login, the lock screen will also use X11.
