I will preface this with the statement that all this is relatively new to me,
but I am learning a lot today (therefore, it is a good day).

I did a glxinfo and was having fun explicitly setting the visual id from the
list for the most part things work as expected...when I choose one without
depth it won't output things in the proper order, when I choose one without
double buffering it flickers like crazy and when I chose (I am not sure what
I was hoping to see):

The graphics crashed and it reset to the login screen:

So, maybe setting the visual id is not a good idea....or maybe it is not a
good idea to let me play unsupervised? ;-)

P.S. I suspect the crosshatching on the Impact with the ICO is a lack of
patches (I will try to verify that in the next few days). I no longer have
the IR to verify what visual I was getting by default.
