In general what is the approach to switch the desktop environment or window manager on Ubuntu? The main difference between stock Ubuntu, Kubuntu and Lubuntu is supposedly the use of Unity vs. KDE vs. LXDE.  However, in order to try various desktop environments and window managers I don't want to have to reinstall the respective flavor from scratch just to get a particular desktop environments or window manager. There probably is an easier method than that.  The question: How can I easily test different desktop environments and respective compatible window managers (say KDE, LXDE, Unity, GNOME, XFCE and StumpWM)?

I am using Ubntu-GNOME 16.04 with GNOME 3.20 When I install Nvidia graphic drivers by sudo apt-get install nvidia-361 , I am facing the following problems. During the installation of Nvidia-361, it asks me to select Default Display Manager with the following options  lightdm gdm3  Consequences of selecting lightdm  : The login screen becomes like this :  I don't want this screen. I want the Default (nice) GNOME login screen. Furthermore.... When I enter my password and press enter, I get this screen for about 5 seconds :  Consequences of selecting gdm3  : Well I get nothing! After rebooting, Ubuntu loads ... then all of a sudden my display turns of. No Light. I have waited enough but alas :( no change. NOTE: I have tried both nvidia-361 in default repositories and nvidia-361 from ppa:graphics-drivers/ppa. No difference. I also tried installing nvidia-364 and nvidia-367 from graphics-drivers:ppa , alas :( no much difference. Using nvidia-364 or nvidia-367 : When I tried these drivers, I could get GUI back. But I got stuck on the login page : login loop

I just installed the Gnome Tweak Tool in order to change my icon theme to Faenza, but it seems to have installed some other program named Caribou, which I think is an onscreen keyboard program, with it. This is absolutely useless for me, and frankly, I hate the fact that it was installed silently and without my permission. When I go to uninstall it, it says that it's part of gnome-shell and requires the un-installation of that as well. What do I do?

From the usual Ubuntu login screen, I click on my name, type my password, and press ENTER.  Screen goes black...and stays black.  I cannot get to my desktop.  If I SSH from another computer and run htop, I can see /usr/bin/gnome-shell is eating up 100% of a single core.  Other than gnome-shell, the system is completely idle.  Load average in htop is exactly 1.00.    Earlier today I left it there for over an hour, but no change.  Since then I've also tried rebooting, but same results.  This desktop was previously working fine, not sure what I messed up.  How can I debug what is happening?

I am a new Xubuntu user. Earlier when using Gnome, I was able to configure several desktop shortcuts, particularly for navigation between workspaces.  But, now in Xubuntu, I cannot find those options.  Where can I find those options.

I had a nice GUI for changing startup applications (after logging in) on GNOME 2. How can I start that application on GNOME 3?   Where can I download it? What is the package name? What command is used to launch it? I have Pidgin still launching on start, but I have converted back to Empathy, so I would like to know how I can remove Pidgin and start Empathy instead.

I have many users at the place I work, expressing the notion of switching to Ubuntu.  Most of them, for whatever weird reason wanting to know if its possible to have refresh added when you right click on the desktop.   Is that possible?

On every boot up I get this:    For about 10 seconds (or more) before the "normal" Ubuntu Gnome loading screen and the login screen comes up.  I've read some questions and a bug report about this already, but this problem was dismissed as a minor inconvenience or there were no real solutions (that worked for me). For me, this problem leads to an unacceptable slow boot compared to Ubuntu (Unity) or Windows.  Does anybody know how to fix this or is this a "feature" of Ubuntu Gnome and not a bug?

Hi I have ubuntu server 10.04 installed and I also installed the following:  su aptitude install xorg xfce4 aptitude install &lt;name of GUI browser, I use firefox&gt; aptitude install gedit aptitude install gnome-terminal   Now when I restart the system it goes to the GUI login, what I am really after is a system that loads the CLI by default and then I can use startx to load the GUI when really necessary. I am trying to learn CLI but I would like to retain access to the GUI for now. And, how can I switch between CLI and GUI anytime?

To better describe the above problem, whenever I start up my Ubuntu/Windows 10 Machine and select Ubuntu, whenever the machine tries to start the GNOME Desktop Environment, it says it started it successfully. however, I never get a graphical desktop environment to use. I can fix this by logging into tty3 and typing gnome-session but I don't really want to do that as, for some reason, that skips login. Can anyone help?

I need to get rid of the GNOME Desktop Environment which has been installed by default when I updated my pc from 15.10 to 16.04.  After a while, I found myself not only with GNOME DE, but also with Cinnamon alongside (in the login screen, I could choose at least five or six DE!)  Now I am using Unity, and I'm happy with that, and I successfully uninstalled Cinnamon, but now I'm afraid that after uninstalling GNOME I will mess up the Unity DE, since I see many packages running in unity with the packagename starting with gnome-... Would someone mind to help me? Thx in advance
