I'm running

  • Ubuntu 16.04
  • compiz 0.9.12.3
  • unity 7.4.5+16.04.20180221-0ubutu1

I have 0 packages to update.

I have an empty screen. The background colour is correct, but the rest of the UI has not loaded. I can open a terminal and then run programmes such as firefox, but I can't change the window sizes or summon their menus by pressing alt. The top bar with the time, internet connection status, etc. is not visible. I can't see the Ubuntu equivalent of the start menu.

Basically unity is not running.

When I log in I get a crash report regarding compiz-config-profile-setter with the error message as in the title. The screen was as I described above. I ran apt-get upgrade but unity is still broken.

I tried running compiz --replace but nothing changed.

Has anyone encountered this? How can I fix it?

  • I've fixed it by removing compiz settings directory: rm -rf ~/.compiz/compiz-1/ – Matías Oct 29 '18 at 14:30
  • That did not fix it for me. – Matt Ellen Nov 1 '18 at 9:13
  • In the end I updated to 18.04. That cleared up this issue, but left me with a bunch of others – Matt Ellen Feb 3 at 14:35

Try this: In ~/.config/compiz-1/compizconfig/config change profile = unity-lowgfx to profile = unity and reboot.

(Tested on Ubuntu 16.04 LTS)

TL;DR

I'm sharing this, because this worked form me, and help me a lot. I hope this will help you as well.
This is for common Ubuntu users as I am.

1] Open terminal with Ctrl+Alt+F1

2] Find config file in compizconfig dir somewhere in your home dir.
(in my case is path ~/.config/compiz-1/compizconfig/config)

3] Edit this file whith your favourite editor (like vim or gedit)

gedit .config/compiz-1/compizconfig/config 

4] You should find there something like:

[general_ubuntu]
profile = unity-lowgfx

change unity-lowgfx to unity so it looks like this:

[general_ubuntu]
profile = unity

5] save changes and reboot Ubuntu (try reboot in command line)
