I just shifted to Xfce desktop and am very pleased with the change.
One VERY minor point is irritating me slightly.
There is a Desktop Setting to "Change the background (in minutes):" but when I set that, it works one time then stays the same until log-out or until I change the timer setting.
For testing, I set it at 1 minute - if I then reset to 2 min & immediately back to 1 min, it changes sure enough after 1 min, but then sticks again.
I have seen other reports of this "problem" but no real explanation or fix.
Of course I can live with it, but it would be nice to fix it!
