I want to install Lubuntu on my old desktop with 128MB of RAM. As the memory is not enough to run the graphical installer, I had to follow the minimal install from a minimal.iso file as described here. However, halfway through the installation when the installer asked me which software I wanted to choose (the list that includes mail server, openssh server...) I chose ubuntu-netbook. That was stupid, because my RAM is really too bad for anything standard.
Now let's say I have Ubuntu (actually the netbook thing, but that doesn't make any difference in this question I think). I have also installed
lubuntu-desktop so I have Lubuntu as well. How can I remove the things that came with Ubuntu, to keep only a fresh Lubuntu installation?
