This seems to only happen to me after a period of inactivity, as i've only seen the dock disappear after logging back in from the lock screen. I can't reproduce it, other than to say it happens about once every week or two.
My go-to solution was to log out and log in again, though I can confirm that Yeou Sunn's workaround of "alt+f2" and "r" works. I'll be doing that for now until a fix is found. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1795703 Title: Ubuntu Dock gets replaced with a standard GNOME one after a while To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-ubuntu-dock/+bug/1795703/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
