Qt 5 on Linux without any window manager (Lighthouse)

  • Imagine that I build a Linux from scratch with OpenGL. Could I run Qt 5 apps with Lighthouse? I don't want to use X11 nor Wayland.

    I have searched a lot but I don't have found it...

    If I remember correctly, it is possible to get Qt to work with the low-level Linux framebuffer. No idea how easy/hard it is though. Try Googling "Qt framebuffer"

  • Yes. You can use the eglfs plugin (qtbase\src\plugins\platforms\eglfs) to make use of EGL functions. Then run your application like this:

    app -platform eglfs

    It's more easier than X11.
