HELP: I Broke Ubuntu By Uninstalling Compiz

rated 0 times [ 1] [ 0] / answers: 1 / hits: 2301 / 2 Years ago, thu, december 9, 2021, 4:28:16

I'm still getting used to Linux, having come from Windows. I was receiving an error that "compiz" had crashed a few times so I figured I'd uninstall it.

sudo apt-get remove compiz

sudo apt-get install compiz

I logged out then back in, after that, the GUI was totally gone and I have no idea how to get it back or what I need to do to restore the GUI to what it was before I killed poor Compiz. GUI was pretty much unmodified after a fresh install of 14.04

How can I fix it? I'm not even sure how to get to a terminal or anything.
The login screen looks normal, but after logging in, it's a totally bare desktop with my backround and a few icons. No Dash, toolbar, etc. Hot Keys don't seem to work either (Super = Dash doesn't work, etc); although I did accidently open "Disk" UI. Not sure how.

Please Help!
Right now I'm working off my W7 dualboot.

In the login screen , select for non-compiz session in the upper right corner (called "metacity" on my pc).

If problem remains, try to install gnome-session-flashback, searching it in the software center or typing this command a terminal :

sudo apt-get install gnome-session-flashback
- To open a terminal with empty desktop, press alt+F2 then type
  
  gnome-terminal
- If ALT+F2 don't work, press ctrl+alt+F1 and type login and password blindly: it will open a terminal.
  
  gnome-session-flashback will give you one more choice in the login screen for another desktop type.

You can also try reinstalling Compiz typing or copying this in a terminal:

sudo apt-get --reinstall install compiz
