A crash must be fixed, anyway. I've experienced it myself. It can be easily replicated using a remote shell to launch gnome-session in an Xvfb display: Xvfb -ac :100 2> Xvfb.log & DISPLAY=:100 export DISPLAY gnome-session --session=ubuntu After that, gdm crashed. I had gdm debug

Tagging rls-ff-notfixing, around 300 reports for 19.10, while it's a bug and ideally we would fix it we don't see a sign at the moment that it's a top priority and needs rls tracking ** Tags removed: champagne ** Tags added: rls-not-fixing ** Tags removed: rls-not-fixing ** Tags added:
