The initial prompt container will be 80 column wide. You may change this with `--width` in case you need more space (for example, to account for large PAM challenge messages). Please refer to usage information (`--help`) for more customization options. Various padding settings are available through the `*-padding` options.
You can instruct `tuigreet` to remember the last username that successfully opened a session with the `--remember` option (that way, the username field will be pre-filled). Similarly, the command and session configuration can be retained between runs with the `--remember-session` option (when using this, the `--cmd` value is overridden by manual selections). You can also remember the selected session per user with the `--remember-user-session` flag. In this case, the selected session will only be saved on successful authentication.

Check the [cache instructions](#cache-instructions) if `/var/cache/tuigreet` doesn't exist after installing tuigreet.
You may change the command that will be executed after opening a session by hitting `F2` and amending the command. Alternatively, you can list the system-declared sessions (or custom ones) by hitting `F3`. Power options are available through `F12`.
