Ubuntu Version: 16.04
I had installed Gnome Desktop environment using sudo apt-get install ubuntu-gnome-desktop
But when I logged out and tried to switch the Desktop environment, clicking on the Unity logo froze the system, and I was only able to move the mouse cursor. I forced a restart and the same thing happened again.
So I went ahead and logged into my account, but I found these problems:
1. The laptop touchpad's taps are no longer recognized as clicks, only the button-clicks are recognized.
2. The Desktop background is black and only the section under the Dock is displaying the wallpaper.
3. The UI of the menus and settings and other parts of the system are shown without any padding, just the plain-text and the system icons have become quite large.
I have tried the following:
Uninstalled all components of Gnome
sudo apt-get upgrade and sudo apt-get dist-upgrade
unity --reset`
sudo apt-get install --reinstall ubuntu-desktop unity compizconfig-settings-manager upstart`And none of these seem to fix the issue(s).
Everything else works fine, I can open the terminal or file manager or the browser.
I do not want to reinstall Ubuntu , please help me fix this mess. Thank you.

I had a similar issue, and was able to solve it with:

Hope that helps!
I had a similar display issue recently (no rendering of outline of buttons/checkboxes/tabs, missing padding between UI elements) - basically my UI looked like garbage - easily noticeable in the 'Calculator' app.
I found that if I switched my theme to 'high constrast', then those things rendered properly - if you have the same symptoms, then the same fix can probably be applied - reinstall the default themes (Ambiance & Radiance):
sudo apt-get install light-themesYou may need to use the unity-tweak-tool to toggle the theme - install it via sudo apt-get install unity-tweak-tool if necessary.
