Hi,

there is no existing way to do that through Wayland. You could force a
VT-switch away, that should put Weston to SLEEPING.

You could write a new Wayland extension, implement it in Weston and
your app, and control the compositor state that way. However, generally
it is a bad idea to let arbitrary clients freeze the compositor, but
you could restrict it to a specific special client.

Why do you want to put Weston to SLEEPING? What would wake it up?


Thanks,
