Thanks for the bug report. Yes, Ubuntu's Onboard adds itself to the login screen on startup. There is bug #938302 for this already, however, having it happen twice to the original poster may be a sign of something else going on.
Questions, Carlos: When you say it happened twice, in different contexts, what contexts were this? There are two workarounds listed in the link to askubuntu.com, did you always use the GUI method? - The GUI method, turning off "Show Onboard when unlocking the screen", would be the most effective one - Onboard should not try to add itself to gnome-screensaver again. You can do the same from command line: $ gsettings set apps.onboard xembed-onboard false - The linked command line method $ gsettings set org.gnome.desktop.screensaver embedded-keyboard-enabled false only keeps Onboard away until it is started the next time. Better use the first method. ** Changed in: onboard (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/986843 Title: Onboard randomly sets as default in lock screen To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/onboard/+bug/986843/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
