Dear Gunnar, Yes, indeed this was the case.
I tried to create my startup files manually in that file directory without using the GUI. And now it seems that these entries are persistent. I don't really understand what the underlying issue is. I will test this for several days more and see if anything changes! Thanks for all your help so far! -Robert -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1619867 Title: Changes to Startup Application Preferences not being remembered in Ubuntu Unity 16.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-session/+bug/1619867/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
