32 So as usual, they are not very Linux friendly.  Figures.  I was hoping
33 that there might be something helpful out there.  Sounds like there is
34 but only in certain cases.  That said, if that will help the OP with
35 only half the games, that is half that can be tested.  Otherwise, one
36 has to play a lot of games and see if it crashes.  ;-)

38 My favorite game, if you call this that, Kpatience.  I play spider
39 solitaire with it.  Sometimes a few other games.  I did play Tux Racer
40 once years ago tho.  I don't recall ever buying a game tho.  I've heard
41 of a lot of them and even seen some run but never was to into it. 
42
43 Maybe some of this will lead to something that can help the OP.
