I have installed ubuntu 16.04 on my laptop. When turning on and logging in, I get a screen with wallpaper and mouse cursor and without panel, dash or ability to open a window, etc. It takes about 5-15 minutes to start the unity desktop. I first thought it does not load at all like this problem: Unity doesn't load, no Launcher, no Dash appears.

the systemd-analyze blam output is:

have you tried all the above methods explained in your link.
you can also try: 

apt-get --reinstall install unity

and if not succeed then,

apt-get install ubuntu-desktop

The Problem was having lots of dotfiles. Since I had moved lots of (about 1 gig) applications to .local/share/applications , The unity has become too slow.
