Accessibility GDM supports "Accessible Login" to allow users to log in to their desktop session even if they cannot easily use the screen, mouse, or key- board in the usual way. This also enables the user to change the visual appearance of the login UI before logging in, for example to use a higher-contrast color scheme for better visi- bility. GDM only supports accessibility with the Standard Greeter, so the "Greeter" parameter in gdm. conf must be set to the Standard Greeter "gdmlogin".
To enable Accessible Login, the system administrator must modify the default login configuration by manually modifying three human-readable configuration files, stored in gdm. conf, AccessKeyMouseEvents, and AccessDwellMouseEvents. To allow users to change the color and contrast scheme of the login dialog, set the "AllowThemeChange" parameter in gdm. conf to "true". To restrict user changes of the visual appearance to a subset of available themes, the "GtkThemesToAllow" parameter in gdm.
conf can be set to a list of acceptable themes separated by commas. conf must be uncommented and set to "true". Also, the "GtkModulesList" parameter must be uncommented and set to "gail:atk-bridge:dwell- mouselistener:keymouselistener". System administrators might wish to load only the minimum subset of these modules that is required to support their user base.
Depending on the end-user needs, it might not be necessary to load all of the GtkModules: o If a user needs the integrated Screen Reader and Magnifier, you must include "gail" and "atk-bridge". o If a user needs a pointing device without buttons or switches, include "dwellmouselistener".
Including all four modules is suitable for most system configurations. The Onscreen Keyboard can operate without gail and atk-bridge, but with a reduced feature set.
For optimum accessibility, we recommend including gail and atk-bridge. When "keymouselistener" or "dwellmouselistener" have been added to the GtkModules loaded by GDM, you can assign user actions to the launch- ing of specific assistive technologies. These gesture associations are contained in the files AccessKeyMouseEvents and AccessDwell- MouseEvents, respectively. The gesture format is described in the two files. The AccessKeyMouseEvents file controls the keymouselistener Gesture Listener and is used to define key-press, mouse button, or XInput device sequences that can be used to launch programs needed for accessibility.
The DwellKeyMouseEvents file controls the dwellmouselistener and supports gestures that involve only motion of a pointing device such as the system mouse.
Motion of an alternative pointing device such as a head pointer or trackball can also be defined. All gestures are speci- fied by the same syntax, there is no distinction between a 'core mouse' gesture and motion from an alternate input device. Motion gestures are defined as "crossing events" into and out of the login dialog window. If the 'dwellmouselistener' GtkModule is loaded, alternative pointing devices are temporarily "latched" to the core pointer, such that motion from alternative devices results in movement of the onscreen pointer.
To use text-to-speech services at login time for instance, when using the Screen Reader in speech mode on some operating systems, the gdm user must be a member of the "audio" group. Logging GDM uses syslog to log errors or status. GDM can also log debugging information, if enabled in the gdm. The output from the session can be found in a file called display.
Four older versions of this file are also stored, by appending 1 through 4 to the file- name. These files are rotated, as new sessions on that display are started.
You can use these logs to view what the X server said when it started up. xsession-errors before even the PreSession script is started, so it is not necessary to redirect this again in the session setup script. If the user session lasted less then 10 seconds, GDM assumes that the session crashed and allows the user to view this file in a dialog before returning to the login screen. This enables the user to view the session errors from the last session and correct the problem.
You can suppress the second warning by returning code 66 from the Xsessionscript or from your session binary the default Xsession script propagates those codes back.
This is useful if you have special logins for which it is not an error to return less than 10 seconds later, or if you already set up the session to display an error message and the GDM message would be confusing and redundant. xsession-errors file is capped by GDM at about kilobytes, to prevent a possible denial-of-service attack on the session. An application could, on reading some wrong data, print out warnings or errors on stderr or stdout.
This could fill up the user's home directory, the user would then have to log out and log back in to clear this. This could be especially nasty if quotas are set. GDM also correctly traps the XFSZ signal and stops writing the file, which would lead to killed ses- sions if the file was redirected in the old-fashioned way from the script.
xsession-errors redirection and redirect in their own Xsession script set by the BaseXsession configuration key , which means that GDM cannot trap the output and cap this file. You also lose output from the PreSession script which can make debugging more difficult, as perhaps useful output of what is wrong is not printed out. See the description of the BaseXsession configuration key for more information, especially on how to handle multiple display managers using the same script.
XXXXXX, where XXXXXX are random characters. xsession-errors file, so that this log file is not stored unnecessarily. conf file, the maximum file size that GDM should accept. If the face browser is enabled, a tunable maximum icon size is also enforced. On large systems, the face browser should be turned off for performance reasons. Looking up icons in home directories, scaling, and rendering face icons can take quite a long time.
In general, GDM is very reluctant to read or write user files. For instance, GDM refuses to touch anything but regular files. Links, sock- ets, and devices are ignored. The value of the "RelaxPermissions" parameter in the gdm. conf file determines whether GDM accepts files that are writable by the user's group or others.
These are ignored by default. Note that normally it is assumed that the home directory is only readable by the user. However, NFS traffic can be snooped. For setups with NFS directories, set the "UserAuthDir" parameter in the gdm. GDM tries to open the normal authorization file for reading as root.
This can be changed by setting the "NeverPlaceCookiesOnNFS" parameter in the [security] sec- tion of the gdm. conf file to "false". The script runs with root privileges and GDM blocks until the script terminates.
Commands to set the background and so on should go in this file too. The system administrator decides whether clients started by the Init script should be killed before starting the user session.
This is controlled by the "KillInitClients" parameter in gdm. When the user has been successfully authenticated, GDM tries the scripts in the PostLogin directory in the same manner as for the Init directory. You have the USER and DISPLAY environment variables set for this script, and again it is run with root privileges.
The script should return 0 on success as otherwise the user is not logged in. This is not true for failsafe session however. After the user session has been set up from the GDM perspective, GDM runs the scripts in the PreSession directory, again in the same manner as the Init directory. Use this script for local session management or accounting. The USER environment variable contains the login of the authenticated user and DISPLAY is set to the current display.
The script should return 0 on success. Any other value causes GDM to termi- nate the current login process. This is not true for failsafe sessions however. After this, the user's session is started.

The GDM package provides the following commands in sbindir intended to be run by the root user:. The gdm command is really just a script which runs the gdm-binary , passing along any options. The gdm-binary is the actual GDM daemon. Gives a brief overview of the command line options. gdm-restart stops and restarts GDM by sending the GDM daemon a HUP signal. This command will immediately terminate all sessions and log out users currently logged in with GDM. gdm-safe-restart stops and restarts GDM by sending the GDM daemon a USR1 signal.
GDM will be restarted as soon as all users log out. gdm-stop stops GDM by sending the GDM daemon a TERM signal.
