Hello,
thanks for the log output but now the only remaining oddity is "No protocol specified". I've looked up a thread of discussion from May 2014

Back then Markus had a very similar problem with OpenSUSE, where the SDL video initialization failed. Please have a look at the discussion and try to check if SDL_SetVideoMode() fails in you case too. You may adapt the patch in one of my postings

By the way, are you running Genode under X.org or directly on the Linux console?
Regards
