On a gnome x11 session everything works fine. Also from testing it looks like KWin has problems with starting a working Xwayland in a nested setup with the OpenGL compositor. OpenGL version string: 3.0 Mesa 12.0.1 – Option 2 works fine (there is no window to resize, after all, – Running startplasmacompositor from a VT did show the splash, but then I just got a black screen with a cursor.

This website uses cookies to improve your experience. While writing the software program, you may have dealt with several commands. Tested nested kwin_wayland on Mageia 6 (Plasma 5.7.1, Frameworks 5.24): the kwin window opens without errors, but when I tried launching kwrite/konsole in it, the window remained black: however, the mouse cursor changed as I moved it, as if the application was there, only invisible, and I’m pretty sure I could interact with it (didn’t manage to save a text file blindly though), Kwin_wayland output: As for elogind libkwalletbackend5-5-5.25.0git.20160724T133134~8cf7300-2.2.x86_64, unfortunately, gnupg still doesn’t have a wayland pinentry client (as far as I understand, the Qt-version uses the Xcb plugin in order to place the window properly and take the focus). lib64wayland-egl1-12.0.1-3.mga6 Content is available under, You want an application to launch in a specific size and position every time, Script the window manager from the command line, Customise the position of titlebar buttons, If you prefer a Classic, KDE3-style Desktop, Open applications directly into a different desktop, KMail's Aggregation options take up too much space, KMail's Folder-List Tooltips hide too many folder names, System Settings -> Application Style -> Window Decorations -> Buttons, System Settings -> Application Style -> Window Decorations, https://userbase.kde.org/index.php?title=KWin&oldid=452243. … It will notify you if it does so, and you can re-enable compositing by pressing Shift+Alt+F12.

From time to time I get contacted because kwin_wayland or startplasmacompositor doesn’t work. KWin has seen many performance improvements to enable these effects even on low-end hardware. works fine and reports wayland windowing system. If I switch to VT2 and run `kwrite –platform wayland`, it seems to show success (“Using Wayland-EGL”), but when I switch back to the first VT, it… well, it doesn’t actually refresh the screen, I still see the contents of VT2, just without the cursor blinking. In other words, bashtop may not be installed, and we need to install the same. GLSL version: 1.40 Reinstalling the application may fix this problem. apt-get remove kwin -y Step 2: The command reads the package lists and proceeds with the uninstallation.
