Enable ReGreet, a clean and customizable greeter for greetd.
|
|
|
|
To use ReGreet, {option}`services.greetd` has to be enabled and
|
|
{option}`services.greetd.settings.default_session` should contain the
|
|
appropriate configuration to launch
|
|
{option}`config.programs.regreet.package`. For examples, see the
|
|
[ReGreet Readme](https://github.com/rharish101/ReGreet#set-as-default-session).
|
|
|
|
A minimal configuration that launches ReGreet in {command}`cage` is
|
|
enabled by this module by default.
