It is the famous GMA500 graphic card problem with linux. There was instructions how to get it to work for ubuntu 14 or so but updates destroyed it. I have never learned how to prevent some packages from updating or how to downgrade them but there was a possibility to usew mplayer with smplayer with vaapi enabled. But if you do not have that laptop and have not updated system do not bother. I just thought if there would have been someone with answers ready. I can use it only for writing and that is why not wanting to go any deeper or take this thread further there. If someone has answers or solutions he/she can pm, if not, letg's drop the off topic subject. Thanks anyway.
