How can someone switch from Kubuntu to Ubuntu? I need the OS to be more lighter than Kubuntu, so I need things to be unistalled from Kubuntu and the LXDE to be installed.

I am talking about 11.10 .

EDIT: I care alot if my system will be lightweight!

This PC is very old.(512 MB RAM)


It may be better to do those operations from a TTY not from a terminal, do CTRL+ALT+F1 and logon on a real TTY.

  1. Optionnal : Uninstall Kubuntu desktop sudo apt-get purge kubuntu-desktop -> It's optionnal because you can have both environements installed but only one running.

  2. Then remove it dependencies sudo apt-get autoremove --purge

  3. After that, install the lubuntu desktop sudo apt-get install lubuntu-desktop

  4. Then, reboot your machine.

Be carefull : this process might corrupt the system, do a backup before proceed.

  • after following these steps and reboot, linux boots up in completely black page without any program loaded, just mouse working and no shortcut do anything. now lost my Linux completely – Woeitg Feb 17 '16 at 20:17
