gtkgreet - A Gtk-based greeter for greetd


gtkgreet [options]


-h, --help

Show help message and quit.

-c, --command <command>

Specifies the command to run on successful login. gtkgreet will ask if none is specified.

-l, --layer-shell

Use wlr-layer-shell to display a window on every output. Must be enabled at compile-time.

-b, --background

Specifies a background image to be used by gtkgreet. JPG and PNG are known to work. The image will be anchored to the upper left corner, and is rendered 1:1 when DPI scaling is 1.

Note: This does not handle scaling values other than 1 correctly. Use a stylesheet for more flexible and correct background rendition.

-s, --style <file.css>

Specifies a custom CSS stylesheet with additional styles for the gtkgreet window. See for the description of CSS subset supported in GTK.

Note: This is not able to load Gtk theme stylesheets, and is only for application-level modifications. To select a theme, use the regular Gtk theme selection mechanisms.


gtkgreet is a Gtk-based, graphical greeter for greetd(1).

gtkgreet allows selection of which application to start at login. See the ENVIRONMENTS section for more information on how to configure the provided options. The user can also specify the application directly at login by writing the command line they wish.

gtkgreet requires a Wayland compositor to run, such as cage(1) or sway(1).


To use gtkgreet, configure a Wayland compositor of your choice to be your greeter. Make the compositor start gtkgreet, and importantly, shut itself down once gtkgreet terminates.

Using cage, the command-line simply becomes "cage gtkgreet".

Using sway(1), one can use a sway config containing "exec 'gtkgreet; swaymsg exit'", and a command-line similar to "sway --config /etc/greetd/sway-config". The "; swaymg exit" component is important, as that makes sway terminate once gtkgreet has finalized a login.

See greetd(5) for information on how to configure greetd. Read the documentation of your chosen compositor for information on how to use it correctly.


The stylesheet can be used to modify styling of gtkgreet elements, such as the window background, fonts, login prompt container and others.

An example stylesheet can be seen here:

window {

background-image: url("file:///etc/greetd/gtkgreet-background.jpg");
background-size: cover;
background-position: center; } box#body {
background-color: rgba(50, 50, 50, 0.5);
border-radius: 10px;
padding: 50px; }


gtkgreet populates the user options for applications to start at login using both a configuration file and the '-c' command-line argument.

The configuration file is read from /etc/greetd/environments, and is a newline-seperated list of of options, each being a command line to run on login if selected.
