I need the mix. I have a lot of code that is in QWidgets and I would like to use QGLWIdget incremently as and when I need it. I was previously using directfb. I enabled opengl without changing anything else, hellogl_es2 lauched but glWidget showed nothing, just some garbage probably due to not clearing the surface. So I swtiched to eglfs that resulted in the current scenario. > > Take qmlviewer or similar and use QGLWidget as viewport for the > QGraphicsView/QDeclarativeView > (-opengl as argument for qmlviewer) > > > > QScreenLinuxFb::connect: No such file or directory > > Error opening framebuffer device /dev/fb0 > > > > : driver cannot connect > > > > Aborted > > > > I don't understand why it needs /dev/fb0. > > QWS != QPA > > They are different, independent Qt ports. > They can't co-exist!
