I've installed MATE desktop (and related packages) from epel on my C7 VM, just to see how it works on C7.
The answer I've got is "not too well", but I fear I may have done something wrong.
Before I go any further, is it not toally unreasonable to ask this here? or should I be banished to redhat bugzilla?
I've got it to the point where when I log in I get top and bottom panels, and desktop wallpaper. But nothing is drawn in front of the wallpaper, and right-click context menu on the desktop doesn't do anything. Everything that I can access thru a panel icon, a panel menu, or a terminal seems to be working.
I did log on epel IRC and talked with "wolfy" about it, but he didn't have any firm answers (several good suggestions, though).
