I don't see the gear button next to the Sign in button at the login screen. I have Nvidia drivers installed (for Nvidia 730 GT card). Ubuntu boots into Xorg as seen from the terminal with echo $XDG_SESSION_TYPE which outputs x11.  How do I switch to Wayland?

Recently I had installed Pantheon (Elementary OS desktop environment). I didn't like it, so I uninstalled it, but Elementary OS Desktop still appear in the title bar. And in the shutdown button menu, Ubuntu Help is replaced by Elementary OS Help.    I want that it says Ubuntu Desktop and Ubuntu Help. How do I fix it?  The output of lsb_release -a is:  No LSB modules are available. Distributor ID: elementary Description:    elementary OS 0.4 Loki Release:        0.4 Codename:       loki   For installation, I use:  sudo add-apt-repository ppa:elementary-os/daily  sudo add-apt-repository ppa:elementary-os/os-patches sudo add-apt-repository ppa:elementary-os/testing  sudo add-apt-repository ppa:mpstark/elementary-tweaks-daily  sudo apt-get update sudo apt-get dist-upgrade sudo apt-get install elementary-theme elementary-icon-theme elementary-default-settings elementary-desktop   For uninstallation, I remove each repository manually, then sudo apt-get autoremove. And the rest with Synaptic Package Manager.

How do I change the default session I get when I log in? I'm on Debian jessie. I tried changing settings on gdm3, tried installing lightdm and following  but it's just not working.  For more specificity, I'm trying to default to gnome-classic instead of gnome. I want to turn on the computer, log in as any arbitrary user, and see gnome-classic, not gnome3 (preferably I'd remove the gnome3 default session, if there's a way to do that).

I have a remote machine running Debian 8 (Jessie) with lightdm installed. I want it to start in no-GUI mode, but I don't want to remove all X-related stuff to still be able to run it though SSH with the -X parameter. So how to disable X server autostart without removing it?  I tried systemctl stop lightdm, it stops the lightdm, but it runs again after reboot. I also tried systemctl disable lightdm, but it basically does nothing. It renames lightdm's scripts in /etc/rc*.d directories, but it still starts after reboot, so what am I doing wrong? And I can't just update-rc.d lightdm stop, because it's deprecated and doesn't work.

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?

I have Ubuntu GNOME 14.04 LTS and from installation, my name has not appeared in the panel. I have enabled it via dconf in org.gnome.desktop.privacy, but it has yet to appear even after a re-login and restart.  Can I receive some assistance into the cause of this and a solution?  This is where I would like it to appear:

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?

Is there a 'Startup applications' app for lubuntu? Or how do I add apps to startup? I attempted a tutorial to add entries to ~/.config/autostart, but it did not work. Isn't there an easy way? Any ideas please?

I have a problem with Ubuntu 13.04.  I cannot log in to my account. I put the right password but there is an endless loop. (if i put wrong pass, it says "Invalid password..."). Also, it doesnt show the small drop down menu with choices "Gnome fallback, Default, etc.."  If i login as guest, the desktop is clear, no bars, no menus, anything. Just right clicks works only.  I have already try  solution ( chown username:username .Xauthority ) but there is no "Xauthority" at ubuntu 13.04. (?)  Is the problem about lightdm? Also, i tried sudo dpkg-reconfigure lightdm but it soesn't work.  I use the recovery mode (root command shell or something like this) in order to try the above commands.  Has anyone a solution?  Thank you.

I was wondering if it is possible to get the GNOME 3.2 GDM login theme working on Ubuntu 11.10. I installed GDM alongside LightDM, but the GDM greeter is really ugly.

I think I messed up my Ubuntu 12.04. I really just want the 'dodge over window' feature that's why I followed the steps here:    And now I have unity version 5.18  But every time I log in, I'm just getting a screen with my wallpaper and a mouse.   I enabled 'unity plugin' in ccsm, but didn't work.  I tried to uninstall unity and did these:   sudo apt-get install ppa-purge  sudo ppa-purge ppa:ikarosdev/unity-revamped  sudo apt-get update  sudo apt-get install unity   but still getting version 5.18. Now I'm thinking the best solution (I think?) is to completely remove unity and all it's components to get version 5.10.  Or if you have a different solution just for me to get back my desktop would be great. Thanks for reading.

So I installed Ubuntu server to run some tests on a VM. For various reasons I couldn't get a specific DEB file, and instead of using a shared folder I decided it would be a good idea to install ubuntu-desktop so I can run Firefox and grab the file directly from the web.   Now, every time I boot my machine I get the graphical interface, but I have no reason for it since I'm running tests with the LAMP server.  I tried this    And this    If anyone has any idea for a solution, I'd appreciate it.   BTW: I thought about simply uninstalling ubuntu-desktop, but I feel like I might need it in the future, so, I really just want to disable the GUI.  EDIT:  While this solution is not perfect I realized, it works for now:  On the  question, user Michael K mentions that:  " Okay another way would be to disable the lightdm service in init:  /etc/init/lightdm.conf   in there there is a section like this:  start on (filesystem and started dbus and (drm-device-added card0 PRIMARY_DEVICE_FOR_DISPLAY=1 or stopped udev-fallback-graphics))   "  While this worked perfectly, I can't access the GUI with the startx command - the system just crashes. And I guess I'll need to uncomment the section to load startx.  Considering the fact that I want to keep the server running for as long as possible, having to restart it every time I want to log in the GUI is kinda unproductive.  EDIT2:  I guess it's possible simply to kill the GUI (  ) when I log in the system, it's still counter productive, but it works too.   EDIT3:   Michael K's reply worked fine. I just realized that to call the GUI I need to run lightdm and not startx

I downloaded a couple greeters for LightDM, but I have not figured out how to enable them. Is there a way to switch greeter, either by graphical or command-line method?. I do not intend to change display manager, nor the background, but to change the layout and appearance of the login screen through a different "theme" (greeter is the name for LightDm themes). Thanks for your time.

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
