This week SDDM–the venerable login manager used by KDE and some other DEs–finally got a new release after two and a half years! This work was pushed through by a variety of KDE contributors, notably Aleix Pol Gonzalez, Fabian Vogt, David Edmundson, and Harald Sitter. At this point they contribute the overwhelming majority of changes and have effectively taken over the SDDM project. Because of this, we’re going to bring SDDM closer and incubate it in KDE for Plasma 6! Once completed, this project will see SDDM release at the same time as Plasma and use Plasma technologies to add many new features, such as management of network and Bluetooth devices on the login screen, and tighter integration with user settings.

In other Plasma 6 news, everything has been fully ported to use KSvg, the new SVG-handling library that can be used outside of Plasma as well. The technical work was almost entirely done by Marco Martin, with me helping out and performing QA.

Additionally, Xaver Hugl significantly improved graphics performance with multi-GPU systems that are using an NVIDIA GPU in the secondary position. Work is also in progress on a massive performance improvement for some Intel GPU users; more on that next week.

Finally, Qt scaling will be used on X11 in Plasma 6, improving the high DPI scaling experience for people not using mixed-DPI multi-monitor setups. That use case is already not supported on X11, so our story remains the same: if you have a mixed-DPI multi-monitor setup, use Wayland! Marco did this too.
