I'm using Ubuntu 22.04 with KDE Plasma DE and gdm3 login manager.

When I open my laptop lid, the login screen shows the title and control buttons for some recent video that I was watching in my browser (Firefox 106 and recent versions, if it matters). I kind of don't want to worry about everyone near me having a good view of whatever pornography I was watching yesterday every time I open my laptop. How do I disable this feature? The DE only has settings for the SDDM login screen, which I'm not using.

As a side question, who in God's name thought this would be a desireable feature?

    Even without porn, it's a terrible idea. login and unlock screens shouldn't leak ANY information about users (and, yeah, drop down menus and other lists of user names on the login screen are a dumb idea too - they give away half of the username/password combination).

  • @jsotola Okay, so I was watching videos of cats pushing things off of tables. The question's still valid: What conceivable purpose does it serve to have my login screen document the fact that the last video I watched was cats pushing things off tables? Commented Nov 20, 2022 at 3:58
  • yes, you are absolutely right ... I wasn't thinking
