Hi, thanks for your response!

I've read that Qt 5 only supports one window at a time. That's why I want 
to use Qt 4.8 with QWS. Or is my information wrong? If it's wrong, I could 
of course switch to Qt 5. 

I'm even not sure if kernel v3.12 is right for me - because I need to 
activate the CAN bus with DTS, which isn't good supported in this kernel. 
I'd prefer to use kernel v3.8, but there is no sgx support. (Nontheless, 
currently I only want to run a Qt OpenGL application, no matter which 
kernel)

Cheers,
Marcel
