I'm running Raspbian “wheezy”, a Debian based Linux distribution for the Raspberry Pi and I would like to know where I can change the desktop environment that boots with the OS. In particular, how can I replace LXDE with a custom QT or Java program?

  • Have you tried using standard Debian tools? As far as I know they should work, the only problem I can think of is I'm almost sure there will be missing packages compared to i386/x86_64.

  • First thing I'd try is placing a .xinitrc file in the default user's home...

  • I have been looking at their documents/forums and as @sr_ suggested they use .xinitrc (located at your home) to exec lxde, so it's just a matter of replacing the line where lxde loads and add your custom program.

You might be able to install Raspbian Lite to your Pi and install a different desktop, but this is not recommended because you may have WiFi connectivity problems. You may also be able to install a display manager with support for desktop switching, for example, GDM, then install a desktop. I don't think anyone has tried this before, and it may be extremely dangerous.

    Try to answer with facts, ideally by citing the source. Also, note that the original question is eight years old. Changing the desktop environment is just an apt-get install away, without extreme dangers.
