Please keep this in mind when changing GDM configuration. - * - * Developers who add new configuration options should ensure that they do the - * following: - * - * + Edit the config/gdm.conf file to include the default setting. - * - * + Specify the same default in this file as in the config/gdm.conf.in file. - * - * + Update the gdm_config_init function in daemon/gdmconfig.c to add the - * new key. Include some documentation about the new key, following the - * style of existing comments. - * - * + Add any validation to the _gdm_set_value_string, _gdm_set_value_int, - * and/or _gdm_set_value_bool functions (depending on the type of the new - * key) in gdmconfig.c, if validation is needed. - * - * + If GDM_UPDATE_CONFIG should not respond to this configuration setting, - * update the update_config function in gdmconfig.c to return FALSE for - * this key. Examples include changing the PidFile, ServAuthDir, or - * other values that GDM should not change until it is restarted. If - * this is true, the next bullet can be ignored. - * - * + If the option should cause the greeter (gdmlogin/gdmgreeter) program to - * be updated immediately, make sure to update the appropriate - * _gdm_set_value_* function in gdmconfig.c. This function calls the - * notify_displays_* function to call when this value is changed, so you - * will need to add your new config value to the list of values sending - * such notification. Supporting logic will need to be added to - * gdm_slave_handle_notify function in slave.c to process the notify. - * It should be clear to see how to do this from the existing code. - * - * + Add the key to the gdm_read_config and gdm_reread_config functions in - * gui/gdmlogin.c, gui/gdmchooser.c, and gui/greeter/greeter.c - * if the key is used by those programs. Note that all GDM slaves load - * all their configuration data between calls to gdmcomm_comm_bulk_start() - * and gdmcomm_comm_bulk_stop(). This makes sure that the slave only uses - * a single sockets connection to get all configuration data. If a new - * config value is read by a slave, make sure to load the key in this - * code section for best performance. - * - * + The gui/gdmsetup.c program should be updated to support the new option - * unless there's a good reason not to (like it is a configuration value - * that only someone who really knows what they are doing should change - * like GDM_KEY_PID_FILE). - * - * + Currently GDM treats any key in the "gui" and "greeter" categories, - * and security/PamStack as available for per-display configuration. - * If a key is appropriate for per-display configuration, and is not - * in the "gui" or "greeter" categories, then it will need to be added - * to the gdm_config_key_to_string_per_display function. It may make - * sense for some keys used by the daemon to be per-display so this - * will need to be coded (refer to GDM_KEY_PAM_STACK for an example). - * - * + Update the docs/C/gdm.xml file to include information about the new - * option. Include information about any other interfaces (such as - * ENVIRONMENT variables) that may affect the configuration option. - * Patches without documentation will not be accepted. - * - * Please do this work *before* submitting an patch.
