I recently decided to install LXDE on my Ubuntu 14.04 (it's not a fresh installation, however it's quite recent). I wanted to use mainly Unity and use LXDE sometimes when I needed higher performance. Following a guide to do this, I used:
sudo apt-get lubuntu-desktop
for getting the Lubuntu flavor. After everything finished I shutdown the computer, for some reason. To my surprise, the shutdown screen as well as the boot one has the Lubuntu logo instead of the Ubuntu one. A minor annoyance as it was nowhere written this would be one of the effects. Then, contrary to what I was made to believe, the login screen is the Lubuntu one. I couldn't find any way to choose the desktop environment from there so I just log in. After I login I see that the desktop is still Unity. To sum up: my LXDE installation made my Ubuntu believe it was Lubuntu, but left the only aspect I installed it for unsolved. After this experience, I decided to uninstall it using these commands:
sudo apt-get autoremove lxde sudo apt-get autoremove lubuntu-desktop sudo apt-get --purge remove lxde sudo apt-get --purge remove lubuntu-desktop
The last two were not necessary, apparently. These operations left the situation unchanged. It also appears that the Lubuntu login screen just covers up the Ubuntu one as for a brief second it appeared after logging in. So my questions are:
- if and how can I reset my system to its former state, and
- can I then install LXDE with the ability to choose between the DEs and hopefully be able to use the programs from Unity on LXDE (ideally without installing its own software again)?
Thanks in advance
