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 Desktop Packages, which is subscribed to gnome-shell-extension-ubuntu-dock in Ubuntu. https://bugs.launchpad.net/bugs/1795703 Title: Ubuntu Dock gets replaced with a standard GNOME one after a while Status in gnome-shell-extension-ubuntu-dock package in Ubuntu: Confirmed Bug description: I don't reboot my desktop and don't hibernate it, it just works for multiple days in a row without a reboot. I only turn off the monitor when I go out. Sometimes, after a while, when I turn on the monitor, Ubuntu's Dock is no longer there and what I get is the GNOME Dock which is hidden and can be seen by pressing "Super" (which shows all windows as well). This is annoying.
