    If you have the disk space, you can add lubuntu-desktop to your system, and then select which you want to use for that session at login. If you find yourself always using lubuntu, you can later remove xubuntu-desktop (this is a variation of @ubuntroll's answer - ie. adding lubuntu first, then the removal later if happy with lubuntu). – guiverc Jun 11 at 7:38
  • how can I addbthe lubuntu? is that like the procedure for the xubuntu? sorry i am a newbie in terms of these – Jan Jun 11 at 7:40
  • As @ubuntroll said; sudo apt install lubuntu-desktop will add it (apt and apt-get do the same thing in this case). The package adds the Lubuntu desktop to your system, including all programs; so you'll end up with leafpad (lxde text editor) and mousepad (xfce text editor), ie. multiple options that do the same thing. LXDE default apps will use less memory, so removing xubuntu-desktop later maybe useful as 1gb isn't much dram. – guiverc Jun 11 at 7:45
  • also please note my use of leafpad/mousepad was intended as example. you'll also end up with pcmanfm/thunar (two file manager), lxterminal/xfce4-terminal, ... for most other applications. this can complicate menu's, increases your updates (as more software will be updated), and it may make no difference to your complaint. In testing Lubuntu & Xubuntu releases on ~2004 era machines I found some models great, others not so good because of hardware inside (ie. intel modules/drivers were just better than radeon...) – guiverc Jun 11 at 8:19

Uninstall xubuntu-desktop:

sudo apt-get --purge --auto-remove xubuntu-desktop

Many more Xubuntu packages may need to be uninstalled, if they were set to manually installed, but my assumption above makes sense; or you may just not desire to remove them all.

Then install lubuntu-desktop:

sudo apt-get install lubuntu-desktop
  • should i download the ISO file of lubuntu when I put that command? – Jan Jun 11 at 7:37
  • @Jan No. But it is preferable to do it while not logged into your lxde. Ctrl+F5, log in, then run the commands. – ubuntroll Jun 11 at 7:41
  • @Jan Sorry, I meant Ctrl+Alt+F5. And the F5 is just an example; any number works in the 2-6 range. Then, to turn back to the GUI, use Ctrl+Alt+F1. You may need to try some other Fs. – ubuntroll Jun 11 at 7:45
  • @Jan If you need me to add more info, I will, just don't forget to mark my answer as accepted if it helped. It will get my score closer to 50; 50 gives me commenting rights. – ubuntroll Jun 11 at 8:12
  • why lubuntu show up in the lock screen (when choosing flavours) even i deleted in the command (sudo apt-get --purge remove lubuntu-desktop) – Jan Jun 11 at 8:42
