What's happening here is that the screensaver kicks in, blanks the screen to black, but ~/Pictures is not shown.
It seems to follow having Caja crash / the window manager decide that it has to rewrite all the windows in all workspaces. Another bunch of debug outputs attached. See the number of times mate- screensaver had to be closed via ^C and restarted. ** Attachment added: "temp.txt" https://bugs.launchpad.net/ubuntu/+source/mate-screensaver/+bug/1783224/+attachment/5425673/+files/temp.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1783224 Title: Mate-Screensaver does not engage after some amount of uptime To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-mate/+bug/1783224/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
