Application start problem with linuxfb
I am using Qt 5.4.1 on Raspberry, compiled via buildroot with eglfs and linuxfb plugin. When I start with eglfs everything works fine. I just cannot get linuxfb working. The application starts but nothing happens (I still see the console). There are no error messages, and the screen is just locked. Even if I kill the application from another terminal the screen stays frozen. I tried directfb but then I just get a black screen with a mouse cursor (here I can kill the application and get back to the console). The framebuffer device works, as I use it with other applications. Does anybody know what might be the problem or how I could possibly debug the setup?
