After extensive testing I can now document how to reproduce the crash using four workspaces and four applications.
With just one workspace enabled, several applications can be started and gnome-shell can be restarted with 'Alt F2 > r and enter' without issue. With multiple workspaces enabled, several applications can be started and gnome-shell can be restarted with 'Alt F2 > r and enter' provided all applications are started on the first workspace. With multiple workspaces enabled, if several applications are started on different workspaces then gnome-shell will crash if restarted with 'Alt F2 > r and enter'. My last application was started on workspace 4. I'm removing any references to the dock from this bug report as it was due to seeing issues which have been reported elsewhere that prompted me to restart gnome-shell. ** No longer affects: gnome-shell-extension-dashtodock (Ubuntu) ** Summary changed: - Dash to Dock behaves strangely then gnome-shell crashes when forcing a restart + gnome-shell crashes when forcing a restart if applications are started on multiple workspaces -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1799787 Title: gnome-shell crashes when forcing a restart if applications are started on multiple workspaces To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1799787/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
