Kind of you to post this.

Odd thing is, I don't recall ever having had to do that on C7/MATE. I'm
running MATE on my Acer netbook (C7), and a couple of VMs that I don't use
much, but use for hacking around to try things before breaking my netbook.

I did install from a Gnome cd/dvd (forget which) but first thing I did was install EPEL and MATE. wonder if Gnome would have pre-done that op for me?
