Thanks for your hint !
But unfortunately it does not help - I can't see anything on the
console.

I also tested a very basic SDL program which simple call

   SDL_Init(SDL_INIT_VIDEO)

That call does not return and let the program hang. So I guess there
is something important missing in my system that inhibit gtk and SDL
from working (maybe some Xorg or kernel stuff). I have to investigate
this.

With regards,
Frank.
