Ubuntu Environment Is Broken

Question

After installation, this PC's Desktop does not look like the Desktop on my other PC.

Answer 1

Your environment isn't broken, it's just some configuration and theme mismatch.

For Unity :

Choice 1 : Reset Unity by dconf reset -f /org/compiz/, for removing compiz configuration use rm -rf ~/.compiz-1 ~/.config/compiz-1 `

Choice 2 : Kind of last resort, reinstall unity by sudo apt-get install --reinstall ubuntu-desktop.

To reset unity icons use : unity --reset-icons

For GNOME :

Choice 1 : Try resetting GNOME by using dconf by command dconf reset -f /org/gnome/.

Choice 2 : Use this command to completely delete your GNOME configs, use with caution. rm -rf .gnome .gnome2 .gconf .gconfd .metacity .cache .dbus .dmrc .mission-control .thumbnails ~/.config/dconf/user ~.compiz*

Choice 3 : Last resort, reinstall GNOME by apt-get install --reinstall gnome-shell.
