When I restarted my Ubuntu after it being updated, I found the Unity launch bar was gone.

I tried looking up several solutions online, blindly typing in the commands that others suggested, and I found after the umpteenth time rebooting after typing in another foreign command, I found I couldn't even open up the terminal with the Ctrl+Alt+t shortcut either and I have no idea how to fix this.

This was the last set of instructions I remember following before terminal stopped opening.

Install CCSM

sudo apt-get install compizconfig-settings-manager

And then run it in terminal (Ctrl+Alt+t)

ccsm

Then search for "Ubuntu Unity Plugin". If it's not checked, check it.

If it is checked you may have another issue. Try restarting compiz:

kill -9pidof compiz`

This will kill it, it should start up again, if it doesn't, CTRL+ALT+F2 and then type:

sudo service lightdm restart

to restart the window manager. Go back to the terminal and run:

unity --reset
