Qml aplication not show when run in xinit

poucz

Hello,
I have embedded device base on debian. I used widget aplication. It starts throught xinit (.xinitrc).

Now I rewrite aplication to QML. When I run xinit, nothing is shown - black screen.
Console output is normal (no error).

I installed xfce4 only for testing. I run xfce4 and than run my aplication in xterm, everything is correct displayed.

There is some diference when run widget or qml aplication by xinit? Need I set some env variable?

Thank for help!

Ok, when you use xinit (X11) you used xcb platform driver.
In documentation there is:

XCB
Note: On some devices there is no EGL and OpenGL support available under X because the EGL implementation is not compatible with Xlib. In this case the XCB plugin is built without EGL support, meaning that Qt Quick 2 or other OpenGL-based applications does not work with this platform plugin. It can still be used however to run software-rendered applications (based on QWidget for example).

When I used linuxfb plugin, it works coretly.

When I tryed eglfs:

./test_program -platform eglfs
 void DEBUG_init() 	  Debug disable
libEGL warning: DRI3: xcb_connect failed
libEGL warning: DRI2: xcb_connect failed
libEGL warning: DRI2: xcb_connect failed
Could not initialize egl display
Neúspěšně ukončen (SIGABRT)

I have all opengl library (I hope).
What does it mean?

Thanks.
