Both LightDM and GDM (GNOME Display Manager) are login managers. They both provide graphical login capabilities (the GUI with the list of the system's users) as well as remote logins using the XDMCP protocol. Ubuntu is supposed to officially replace GDM in favor of the lighter and more easily customizable LightDM You can have both of them installed (or add ...


GDM was switched out for LightDM, so: sudo stop lightdm Or in your service parlance: sudo service lightdm stop For future reference, all these upstart services (that can be run with initctl's service command and shortcuts) are .conf files in /etc/init/


Replacing Desktop By An Application Define User Defined Session First we will have to define a User Defined Session that handles the special case when no desktop should be loaded. We will define this session by creating a custom.desktop file in /usr/share/xsessions/ with a content similar to this: [Desktop Entry] Name=Custom Comment=Custom Session to run ~...


I have the same issue seems like gnome-settings-daemon is not loading monitors.xml at startup my work around is to run this command pkill -9 -f gnome-settings-daemon as a "Startup Application" i have documented this in my ubuntu 14.04 update and problems post not sure if there is a better solution


Edit the file /etc/gdm/gdm.schema find the section that currently looks like this: <schema> <key>greeter/Exclude</key> <signature>s</signature> <default>bin,root,daemon,adm,lp,sync,shutdown,halt,mail,news,uucp,operator,nobody,nobody4,noaccess,postgres,pvm,rpm,nfsnobody,pcap</default> </schema> ...


this may fix the problem. If you are stuck with no mouse movement on your laptop (touchpad) then press the key combinations Alt+F2 and type in gksudo modprobe -r psmouse Type in the password, press enter, and then press Alt+F2 again for entering the following gksudo modprobe psmouse Thats it. Your mouse pointer will start working again. If you like ...


Switching from LightDM to the "older" GDM is very easy, and need not even involve opening a terminal. Note: If you need/want to do this from a terminal (e.g. recovery console), please scroll below the screenshots for a how-to. Also, the "new" GDM is not covered here because it is not officially available for 12.04 and the unofficial packages do ...


For newer GDM 3.X, old answers don't work, except for this one The greeter setting in custom.conf is obsolete, i.e. it won't work anymore. One easy workaround if you want to avoid changing the uid of the user: Open the terminal, and enter (replace user with the username you want to hide from the login screen): sudo nano /var/lib/AccountsService/users/user ...


Use ctrl+alt+F1 to switch to terminal, login run sudo service lightdm stop, lightdm and xserver should be stopped now (check with ctrl+alt+F7, which is your current xorg session, it should not show any desktop now) do your things run sudo service lightdm start to start lightdm and xorg again. Good Luck!


You seem to have configured gdm correctly, but you did not actually stop lightdm. Logging out doesn't stop it. After doing sudo dpkg-reconfigure gdm, you need to stop lightdm sudo service lightdm stop and start gdm sudo service gdm start Hope this helps.


In Ubuntu 10.4 you should refer to Upstart which handles starting of tasks and services during boot, stopping them during shutdown and supervising them while the system is running. Upstart handle start of gdm, so you should edit /etc/init/gdm.conf # sudo vi /etc/init/gdm.conf Default runlevel in ubuntu 10.4 is 2 so you must ...


Let me first tell you that now Ubuntu does not use GDM as its display manager in version 12.04...It uses lightdm as its display manager... So the screen you want is actually lightdm. So you will have to install lightdm as follows. Enter these commands in the terminal: sudo apt-get install lightdm Install lightdm After installing lightdm enter the ...


The login screen doesn't simply sort by name. In fact, in lucid, the default login screen sorts first by usage frequency, and by display name as a fallback. So your mother will show up first after a few times.


The reason that doesn't work is because Ubuntu 11.10 has switched from GDM to LightDM. Try this command instead: sudo service lightdm stop


The default in Ubuntu is LightDM, but if it works I see no reason to lose sleep over it. I am not aware of any difference between the two from a hardware performance aspect.


Install x11vnc on the remote We assume a working ssh setup has already been done. user@remote: sudo apt-get install x11vnc Remote login with GDM We assume that a successful vnc setup has already been done. user@remote:~$ sudo x11vnc <options> x11vnc will use our predefinded VNC settings and passwords. For further options see the manpage and ...


Use this command in the terminal: sudo cp /usr/share/applications/gnome-appearance-properties.desktop /usr/share/gdm/autostart/LoginWindow Logout, and you will be prompted with the Appearance window. change the theme as you change it for the desktop, and login back, and type this command: sudo rm /usr/share/gdm/autostart/LoginWindow/gnome-appearance-...


GDM You can't make the lock screen look like the login screen. However, you can use a theme for the lock screen. There are quite a few available at Here's an example.


Do: sudo dpkg-divert --rename --add /etc/init/gdm.conf Which prints: Adding `local diversion of /etc/init/gdm.conf to /etc/init/gdm.conf.distrib' This will allow you to disable GDM while preventing package upgrades from putting the file back in place and allowing the GDM package to upgrade the configuration file. In the case of 11.x and above lightdm ...


Finally, found a solution for this: From #696855 - How do you hide the mouse pointer under Linux/X11? - Stack Overflow; I heard about unclutter, so just ran sudo apt-get install unclutter And then put the following in a script on the desktop, called, say unclutter -idle 1 -root -grab -visible ... and make sure you've done chmod +x ...


Hacky but you can modify the user's id so they don't show in the list: sudo usermod -u 999 <username> This works because users with id under 1000 are considered to be "system" users (i.e. not humans). The only other way I know is to hide the list completely: sudo -u gdm gconftool-2 --type bool --set /apps/gdm/simple-greeter/disable_user_list 'true'...


The normal way : Go to System -> Administration -> Language Support On the Text Tab, choose your prefered language to display numbers, dates, ... The advanced way for your Desktop Applet : Press Alt+F2 Type: gconf-editor & Hit return Navigate to “Apps > Panel > Applets > Clock_Screen0 > Prefs” Double-click on the ‘Format’ value. Change it to ‘24-...


In recent versions of Ubuntu, gdm has been replaced with lightdm - this is why you don't have a gdm.conf. To set lightdm to be started manually, create an 'override' file for its init configuration: echo 'manual' | sudo dd of=/etc/init/lightdm.override (this just creates a file, called /etc/init/lightdm.override, containing a single line that says manual) ...


Elaborating on Gilles's comment to the accepted answer, here's what I believe is the current "best practices" (Gnome-safe) way to do this. This change will also be reflected in the Gnome "Indicator Applet Session". This method is that one suggested in the docs at the GDM website, and though both the site and Gilles show the addition of "nobody" to the ...


Found it. /etc/gdm/PostLogin/Default for login script /etc/gdm/PostSession/Default for logout script I figured from Florian's suggestion that there should be something for gdm that did it :)


If it's "just" a compiz crash, you should be able to restore it from one of the TTYs, even if the keyboard isn't working in X. hit ctrl+alt+F1 to get to the console Login with your usual username and password Type the following: DISPLAY=:0.0 compiz --replace & If compiz is still really hanging, you may need to kill it with more authority and try ...


Recent versions of Ubuntu are using upstart instead of SysV init. Rename /etc/init/gdm.conf to /etc/init/gdm.disabled. For Kubuntu, rename /etc/init/kdm.conf to /etc/init/kdm.disabled.


If you like the GDM themeability - MDM is great! MDM is currently part of the Linux Mint repository - after contacting the Andrew of he has also packaged this in his PPA. Great going Andrew! The following has been tested on 12.04 Ubuntu in a VM. It also has been tested independently on 12.04 Xubuntu. Until then (and assuming you understand ...


This depends on what you want to do with the login screen. You can configure some basic options in the Login Screen Settings app (System/Administration/Login Screen) - whether a user should be automatically logged in, the default session etc. However to change the login screen more graphically Ubuntu Tweak can be used to change the background, logo etc.
