I will describe the steps I did before the issue appeared:

  1. Running Unity, I wanted to have different wallpapers on each workspace. I followed these steps.
  2. After restart, no top panel appeared, no window borders etc. I had this issue before, after using Compiz (I hope I will not be tempted again to use Compiz).
  3. I switched on tty1, and I installed lubuntu-desktop.
  4. I added a new user <olduser>clone, on Lubuntu.
  5. I logged in as <olduser>clone with Unity, which was working fine.
  6. Being logged as <olduser>clone I managed to add different wallpapers on each workscape, without problems.
  7. I didn't like how they were working, and I decided to uninstall Compiz.

  8. I tried to uninstall lubuntu-desktop and its dependencies:

    sudo apt-get remove --purge lubuntu* sudo apt-get remove --purge abiword*

After restart nothing appears, just black screen. However, I had access to tty1. I installed back lubuntu-desktop.

Now Unity works fine, but combined with Lubuntu desktop.

I migrated all the files from the old user to its clone and renamed the <olduser>clone into <olduser>.

How can I remove lubuntu-desktop and its dependencies, without destroying Unity?

So you've sudo apt-get remove --purge lubuntu* and apt-get install --reinstall ubuntu-destkop already, but some of the CCSM you did before are probably still lingering around.

So I would:

  1. Take a system back-up (Read this Q&a)
  2. Take a file backup (if your /home is on a separate partition)

  3. Remember that Ctrl+Alt+F7 brings you back here!

    Go to TTY1 by pressing Ctrl+Alt+F1.

  4. sudo apt-get purge ubuntu-desktop
  5. sudo apt-get purge unity
  6. sudo apt-get install ubuntu-desktop
  7. sudo apt-get install unity
  8. Ctrl+Alt+F7 to get back to the GUI login

Why? The purges will remove any lingering configuration settings and the installs will then reset everything to scratch

Warning This is for a plain Vanilla Ubuntu with Unity. If you're running Kubuntu or Gubuntu, all bets are off! ;-)
