        Hello everyone!

        Is there any way to open GUI apps from the command line app? I'm trying to open a SDL2 game that I compiled from the phone itself and this is the error that I get:

        [2018-08-20 17:18:10.193243] <ERROR> MirConnectionAPI: Caught exception at client library boundary (in release): /build/mir-0.24.20ubuntu11+ubports+0~20180312130613.14~1.gbp8ec514/src/client/rpc/stream_socket_transport.cpp(168): Throw in function virtual void mir::client::rpc::StreamSocketTransport::send_message(const std::vector<unsigned char>&, const std::vector<mir::Fd>&)
        Dynamic exception type: boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<mir::socket_disconnected_error> >
        std::exception::what: Failed to send message to server: Broken pipe
        32, "Broken pipe"
        Sys_Error: Error while initializing SDL: Failed to connect to the mir server: Failed to connect: not accepted by server
        

        Sorry if this question has been asked before, but I'm pretty new to this platform and it's difficult to find specific information about certain components of the OS.

          @nikalon afaik you can start GUI apps from CLI but inside Libertine, but let's see if anyone has any trick hidden in his/her sleeves 🙂

            @nikalon you have to "trick" Unity8 into allowing the application to connect. I have not tried it recently, but something like this... https://lists.ubuntu.com/archives/mir-devel/2015-September/001267.html

                Yes! That works, thank you! For anyone who wants the answer you have to append the paremeter --desktop_file_hint=unity8 or -- --desktop_file_hint=unity8 to a regular binary you want to open. This is the syntax:

                ./application -- --desktop_file_hint=unity8
                

                Unfortunately the game crashes because of some OpenGL problem that I don't know how to solve yet:

                library "/vendor/lib/egl/libGLESv2S3D_adreno.so" not found
                
                ----- Initializing OpenGL -----
                Initializing OpenGL subsystem
                Using 8 color bits, 24 depth, 8 stencil display
                shutting down: Unable to initialize OpenGL (glAccum)
                idRenderSystem::Shutdown()
                Shutting down OpenGL subsystem
                Sys_Error: Unable to initialize OpenGL (glAccum)
                shutdown terminal support
                
                

                But that's an unrelated question that I should ask elsewhere.
