I installed a few DE's on that Toshiba hybrid graphic laptop because bumblebee would not work with it, and I with the help of several experienced users here got a couple that do work well.
I kept Xfce and Cinnamon(for now),and will look at Enlightenment(because it is touted as fast).

My question is about getting rid of the 'dross' left over after I uninstalled the ones I did not want via YaST.

Is there and easier way than going through each DE to find out what it installs, and removing them manually?
