I had my lmde machine with cinnamon by default. I just installed kde but there are a few things that are not working. I can use two finger scrolling, pinch and zoom with my touchpad in cinnamon and gnome, but the same doesnt apply when I'm logged into my kde desktop. Also, in kde, volume controls dont work. I cant increase or decrease my volume using the volume keys from the keyboard. Any ideas on why kde is the odd one out?
