Ubuntu – How to configure a Minimal Ubuntu installation

ubuntu-minimal

I recently re installed Ubuntu using the mini.iso, but much to my dismay the mini.iso is not configured the same way as the Ubuntu desktop ISO some "problems" I'm facing such as:

  • An Installation using the regular Ubuntu CD recognizes my active
    network connections in Network Manager, Installing with the
    mini.iso gives me a working connection however no connections are "active" in Network Manager displaying the message "The system
    network services are not compatible with this version."
  • In a regular Ubuntu install connecting an Android phone to the PC
    mounts the phone's internal memory and sd card if present, Using the
    mini.iso the phone is detected as it appears with the command lsusb but it's not mounted and can't be mounted.
  • In the same regards using the phone to tether it's connection to the
    PC via USB, the phone is connected to my (WiFi). In the regular Ubuntu
    install the phone is recognized as a networking device and is used as
    connection usb0, while in the mini.iso nothing happens, and
    trying to add the connection to /etc/network/interfaces results in
    the OS crashing.

Just to make sure It wasn't a matter of my user not having the correct permissions or a lack of "groups", I've checked with an Ubuntu VM and the groups are the same, the networking files are the same, and the packages (except those of ubuntu-desktop such as Unity, Firefox, LibreOffice, and other non-essential software) are Installed in my PC, so what else is there to look for?.

I'm sure I'm missing something, and I'd prefer not to install Ubuntu again, using the regular cd.

How can I manage to get the same behaviour/configuration without reinstalling ?

Your problem is that the display manager you are using -- SLiM 1.3.2 -- DOES NOT integrate with the ConsoleKit/PolicyKit authentication framework used by Ubuntu.

You need to use a display manager which does support CK/PK (e.g. GDM, KDM, LightDM, XDM...), or install the newest SLiM 1.3.4 (from Quantal) which DOES support CK/PK:
