Everything works fine, except that I do not understand the messages in
Xorg.0.log :)
Its written that the fb and vesa drivers are loaded by the x server. I
have no xorg.conf in /etc/X11.

Shouldnt one of intel or nouveau drivers get loaded?
Is there anything "wrong" or is it ok that the fb driver is loaded?
Thanks for clarification!
