Overview of changes in lightdm 1.16.0 * Update default configuration better explaining the seat configuration name matching and dropping references to the obsolete [SeatDefaults] section Overview of changes in lightdm 1.15.3 * Drop Xorg option -sharevts. It's no longer required for non-seat0 X servers since xorg-server release 1.16. Overview of changes in lightdm 1.15.2 * Support Wayland sessions. * Implement autologin-session option. * Generate Vala bindings from GIR instead of manually writing them. This fixes some small bugs in both the Vala and GIR bindings. * Don't remove autotools generated files in distclean. Overview of changes in lightdm 1.15.1 * Fix default X server command set to XMir in 1.15.0. * Internally merge the [SeatDefaults] and [Seat:*] sections together.

Users should set [SeatDefaults] section with settings for all seats, and can override each setting in a per seat configuration. - Default seats are now specified using a [Seat:] section. If no seats are specified then one is started. This can be overridden by setting start-default-seat=false in [LightDM]. - Support setting autologin user to guest account - Split the user accounts configuration into /etc/lightdm/users.conf so the main config can be private. - The default user session is now "default". Distributions should put a symlink to their chosen default or set one in lightdm.conf. - XDMCP keys now stored in keys.conf * liblightdm API changes: - Both libraries are now version 1 and have API and ABI guarantees. - Face images are now local paths not URIs - liblightdm-gobject now uses lightdm_ prefix instead of ldm_ - Non-greeter functions are now moved out of the Greeter class - connect_to_server() is now called connect_sync and blocks until completion. - start_session() is now called start_session_sync and blocks until completion. The quit signal is removed, and the greeter should quit if this method returns TRUE. - login() is now called authenticate() - Greeters now have hints instead of configuration (greeters should load their own configuration from /etc/lightdm if they need it). - liblightdm-gobject uses AccountsService if it is available - Added regression tests for liblightdm-qt * D-Bus API changes: - Expose Seats and Sessions on org.freedesktop.DisplayManager - Add a CanSwitch property - Rename ShowGreeter() to SwitchToGreeter() * Greeter changes: - Drop "example" from the name of the GTK+ and Qt greeters and make them official default greeters. - Use GTK3 for GTK+ greeter. - Removed the Vala and Python GTK+ greeters, they weren't being well maintained. Overview of changes in lightdm 0.4.4 * Fix failure to accept XDMCP connections due to invalid assert. * Allow minimum-display-number to be set in lightdm.conf and on the command line. * Session X authority now written to ~/.Xauthority by default. It can be configured to run from the system location by setting user-authority-in-system-dir=true in lightdm.conf. * When using system authority the authority can be updated by the user. * Written X authority files now checks hostname and display number. * Environment is no longer passed through to X servers and sessions, this is no longer required now PAM works correctly. * liblightdm API changes: - Drop ldm_greeter_get_is_first() - it was added for testing and doesn't work well. * Fix more errors where authentication messages from previous sessions could be confused with new sessions. * Added XDMCP regression tests. Overview of changes in lightdm 0.4.3 * Don't replace Plymouth if it isn't running on a valid VT * Allow a null username to log in with - the system will prompt for a username. * liblightdm API changes: - Rename ldm_greeter_provide_secret to ldm_greeter_respond - responses may not be secrets. - show-prompt signal now has a PromptType field - show-message signal now has a MessageType field and takes over behaviour of show-error signal * Fix error where an authentication failure from a previous session could be interpreted as a failure in the current session. * Simplify Vala bindings and add missing methods Overview of changes in lightdm 0.4.2 * Fix errors communicating with PAM * Fix interaction with Plytmouth. * Removes the vt option in lightdm.conf, this is no longer required and the active is used for the first display if Plymouth is detected. A new option minimum-vt is added to select the first VT to be used for other displays. * On login switch to an existing session if already logged in with that username. * Correctly connect up D-Bus interface for user switching Overview of changes in lightdm 0.4.1 * Fix linking issue with -z,defs * Added guest account support * Restart X server if it crashes during a session * Don't set language environment variables, use the daemon values (system default) and leave it to ~/.profile for users to set these * Change greeter library API, starting a session no longer has a language option * Fix greeter crash when user accounts change Overview of changes in lightdm 0.4.0 * Fix crash when child processes quit * Fix crash when catching signals * Fix crash when session quits after X server * Add internal checking for NULL object access * Correctly handle signals from external programs (Thanks to Jason Conti) * liblightdm API changes: - ldm_greeter_start_authentication becomes ldm_greeter_login - The existing ldm_greeter_login is now ldm_greeter_start_session and the username parameter is not required. - Drop ldm_greeter_get_default_layout (X controls the layout) * Configuration changes: - Use /etc/lightdm/lightdm.conf instead of /etc/lightdm.conf - The "displays" item is now called "seats".
