WOW! Thank you Scotty_Trees
Yes you are right I have 4GB RAM, and I don’t do extensive stuff.
I will see if I can get my XFCE desktop to its default look (Get Default View Back?). I know I am naughty and playing around a lot and messing things up!) But I’m addicted since I was a kid to be naughty, even now at this age!
FYI, the reason I was thinking of KDE is sorted out as I installed Dolphin which pulled Baloo with it and everything is fine with me now. (other than the look I messed as mentioned in the other thread).
If I got it sorted out I’m fine… (though I’m sure I’ll mess things up again 
)
Thank you very much. I’ll go through the links you provided.
