I installed Elementary OS Desktop on Ubuntu 14.04, and after that I removed it, but it's not completely removed.

I have changes in Unity, for example:

  • Install unity-tweak-tool with sudo apt-get install unity-tweak-tool, then run the application and change the theme.

Reset Unity:

unity --reset

Or you can try to

Reset Theme:

gsettings set org.gnome.desktop.interface gtk-theme ''
gsettings set org.gnome.desktop.wm.preferences theme ''
  • --reset deprecated and it is reset, your answer no solution for me!

    Run software-properties-gtk in Terminal, then make sure the theme's ppa's are all checked/enabled. Then do the following: 1) sudo apt-get install ppa-purge 2) sudo ppa-purge ppa:elementary-os/daily

Test this:

Switch on your computer.

Press and hold the Shift key, which will bring up the Grub menu.

Select the line which starts with Advanced options.

Select the line ending with recovery mode

Your PC should display a menu with a number of options.

Select In this order: Network -- Drop to root shell prompt.

In the terminal run:

mount -o remount, rw /
mount --all
apt-get update
apt-get install --reinstall aptitude deborphan
aptitude remove '?and(?reverse-depends(elementary),?not(?reverse-depends(?exact-name(ubuntu-desktop))))'
apt-get install --reinstall ubuntu-desktop
apt-get dist-upgrade
apt-get --purge remove $(deborphan)
deborphan --libdevel
apt-get --purge remove $(deborphan --libdevel)
deborphan --find-config
dpkg --purge $(deborphan --find-config)
apt-get autoremove
apt-get clean


  • Thanks, But I now re-installed Ubuntu. Oops.!
