Chiming in to say that this affects me too. Further detail I can add:
* This affects three systems I have installed it on, two laptops, and a desktop. All use intel graphics. * In all cases, disconnecting a monitor crashes the session (but not all of X11, I can still see mouse) * In all cases, using another DM I cannot recreate the failure. It also is still happening on Kubuntu CI branch, so it hasn't (yet anyway) been fixed upstream -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1425961 Title: kscreen no longer detecting disconnection of primary external monitor To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kscreen/+bug/1425961/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
