[kubuntu] Version 16.04 Very long boot time

I recently upgraded to version 16.02

I have a number of observations.

First I see a long lost of detail with OK at the left hand side. Is this normal?

When I type in my password it takes about five minuted for the next screen to appear. This is far too long.

I also have to type my wifi password in at each session.

I suspended a session, and later pressed the button on the Dell tower to re-activate the session, the screen went black and I had to reboot.

I have created four virtual desktops and activate the cube, but it appears not to wok. I also want independent desktops but can see the box.

I'd like Homerun kicker back

Any help appreciated
