Start the budgie desktop environment
Synopsis
budgie-session [-a|--autostart=DIR] [--session=SESSION] [--failsafe|-f] [--debug] [--whale]
Description
The budgie-session program starts up the budgie desktop environment. This command is typically executed by your login manager (either gdm, xdm, or from your X startup scripts). It will load either your saved session, or the default budgie installation on your system. Note that budgie-session is a wrapper script for budgie-session-binary.
$XDG_CONFIG_HOME/budgie-session/sessions, $XDG_CONFIG_DIRS/budgie-session/sessions and $XDG_DATA_DIRS/budgie-session/sessions.
When saving a session, budgie-session saves the currently running applications in the $XDG_CONFIG_HOME/budgie-session/saved-session directory. Saving sessions is only supported with the legacy non-systemd startup method.
budgie-session is an X11R6 session manager. It can manage budgie applications as well as any X11R6 SM compliant application.
Options
The following options are supported:
- --autostart=DIR
The directory DIR to be searched for autostart .desktop files. This option can be used multiple times. When this option is present, then default autostart directories will not be searched.
- --session=SESSION
Use the applications defined in SESSION.session. If not specified, budgie.session will be used.
- --builtin
Use the legacy non-systemd method of managing the user session.
- --failsafe
Run in fail-safe mode. User-specified applications will not be started.
- --debug
Enable debugging code.
- --whale
Show the fail whale in a dialog for debugging it.
Session Definition
Sessions are defined in .session files, that are using a .desktop-like format, with the following keys in the budgie Session group:
- Name
Name of the session. This can be localized.
- RequiredComponents
List of component identifiers (desktop files) that are required by the session. The required components will always run in the session.
Here is an example of a session definition:
[budgie Session] Name=budgie RequiredComponents=budgie-desktop;gnome-settings-daemon;
The .session files are looked for in $XDG_CONFIG_HOME/budgie-session/sessions, $XDG_CONFIG_DIRS/budgie-session/sessions and $XDG_DATA_DIRS/budgie-session/sessions.
It is best to use --builtin if session customizations are required. This is due to the way that budgie currently defines the components that will be started on each session type.
Environment
budgie-session sets several environment variables for the use of its child processes:
SESSION_MANAGER
This variable is used by session-manager aware clients to contact budgie-session.
DISPLAY
This variable is set to the X display being used by budgie-session. Note that if the --display option is used this might be different from the setting of the environment variable when budgie-session is invoked.
Behavior of budgie-session ifself can be modified via the following environment variable:
GNOME_SESSION_AUTOSTART_DIR
This variable specifies a list of directories to the searched for autostart files. This variable overrides all directories specified via the --autostart option, as well as all default autostart directories.
Files
$XDG_CONFIG_HOME/autostart $XDG_CONFIG_DIRS/autostart /usr/share/gnome/autostart
Applications defined via .desktop files in those directories will be started on login.
$XDG_CONFIG_HOME/budgie-session/sessions $XDG_CONFIG_DIRS/budgie-session/sessions $XDG_DATA_DIRS/budgie-session/sessions
These directories contain the .session files that can be used with the --session option.
$XDG_CONFIG_HOME/budgie-session/saved-session
This directory contains the list of applications of the saved session.
