Is anyone out there running @xfce_blog on @debian specifically for me this is Debian 11. ?

I have set the power manager to blank screen after 20 minutes only it does so after about 1 minute. Just wondered if anyone else has had a similar issue ?

I have made a blog post but decided to also make a post here too
