I am on Xubuntu 13.10 and installed the meta package ubuntu-desktop about one hour ago to try it out. Unfortunately, it did not work well at all so I just went back to my Xfce-session.

Now there are some things different and I'd like to remove the packages which came with said meta package. Is there a way to install the ones which just were installed by ubuntu-desktop? Maybe it can be done via some apt-get magic?

Try with sudo apt-get purge --auto-remove ubuntu-desktop, but be careful to read what packages are going to be uninstalled! –  edwin Jan 26 at 0:14

The situation you are in is not uncommon and has been tackled in Getting back to a pure Xubuntu but those instructions are for older versions and not for 13.10. Even then, they have useful pointers and are worth a look.

You can do something like that yourself because whatever you've done by way of installing or removing software from the repositories using apt-get or the Software Center or Synaptic is recorded in /var/log/apt/history.log (and older archived files) in /var/log/apt. What you've done should be in the latest file, plain history.log. Take a look in there and make a note of the software installed on the relevant date.

Then, for simplicity and ease of monitoring what you're doing, purge a few programs at a time from the list of what you've identified. Each time first use the -s flag:

sudo apt-get purge -s package_name

to simulate what will be done without the -s switch.

Also, look in /usr/share/xsessions (using a terminal so that you see the real file names) and delete (after making a backup) the .desktop files of the sessions you don't want to see at log-in time.


Experts may have a more elegant way to grab the package names from the relevant line in history.log but here's one way using your pastebinit content:

  • copy line #3, the one beginning with "Install:" to a text editor, and delete upto the first package name. Save the file as unity.
  • open a terminal and run sed -i 's/), /)\n/g' unity. This introduces line breaks after each package.
  • run awk -F: '{ print $1 }' unity > unity1. This gives you a file with just the package names usable by apt-get. But each package is on a separate line.
  • fix that by running awk 1 ORS=', ' unity1 > unity2
  • manually remove the "," at the very end of the file**.

After these steps, you're left with something you can use in apt-get purge.

Yup, exactly, those instructions are all not for 13.10 which is why I opened the question. :/ Alright, so far so good, your advice was really helpful. :) Found the instance which said that ubuntu-desktop was installed: paste.ubuntu.com/6819219 . I'm sure I could somehow "grab" the packages of that exact line of code in history.log and remove them, and then add ` && sudo apt-get install xubuntu-desktop` afterwards. Hm... –  henry Jan 26 at 9:41
    
answer updated to include a way to process the pastebinit info to something usable –  user25656 Jan 26 at 12:50
    
Thanks for the heads up, I hadn't noticed. Although I found that I somehow managed to overcome some problems (such as keyboard shortcuts not working anymore), I chose another way (sudo apt-get purge --auto-remove unity*). However your suggestion seems to be very sound and thus I'm marking it. –  henry Jan 27 at 19:41
