When I start Ubuntu it enters tty[1-6] instead of my desktop (How do I get to desktop?)

"My solution has been to edit the file /etc/lxdm/default.conf
and set the server section this way

[server]
## arg used to start xserver, not fully function
arg=/usr/bin/X -background vt1"

"Solution 1: See if this works for you:

First, open terminal by: CTRL+ALT+F1

sudo dpkg --configure -a
sudo apt-get update
sudo apt-get upgrade -y
sudo reboot

Solution 2: If the above doesn’t work, try this

First, open terminal by: CTRL+ALT+F1

sudo apt-get update
sudo apt-get install --reinstall ubuntu-desktop
sudo apt-get install unity
sudo shutdown -r now

Solution 3: If none of the above work for you, try this:

None of the above worked for me however, so I upgraded my Ubuntu from 14.04 to Ubuntu 16.04. All my previous files were preserved.

First, open terminal by: CTRL+ALT+F1

sudo do-release-upgrade"

"Login, and type: /etc/init.d/gdm restart
This should launch Gnome Desktop Manager."

Try Control-Alt-Fn-F7 instead of Control-Alt-F7
