Another addition: The Wayland session turns out to be affected as well, but I wasn't able to figure out the precise reason why this is happening yet.
I have a number of extensions installed, and I could -- for the moment -- fix the problem by switching them all off, except the ubuntu-dock. Then I brought them back one by one, but so far it didn't break again. When the problem is affecting my system, the lock screen also behaves very strangely. Hitting Super-L first brings me to a screen where I can see my background and the top panel (responsive). Hitting Super-L a second time makes the top panel transparent (I can still see the date and time). Hitting it a third time brings me to a pure purple screen where I can enter my password. That brings me back to my background and top panel, but without the ubuntu-dock. I have Guake running, but it won't open, neither can I open a gnome terminal with Ctrl+Alt+T. I can do Alt+F2 and try something like gnome-shell -r, but as described before that will end the session (X) or do nothing (Wayland). ** Summary changed: - Ubuntu Dock is missing after unlocking screen (Xorg sessions only) + Ubuntu Dock is missing after unlocking screen -- 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/1796265 Title: Ubuntu Dock is missing after unlocking screen Status in gnome-shell package in Ubuntu: New Status in gnome-shell-extension-ubuntu-dock package in Ubuntu: New Bug description: After locking the screen, unlocking it again does not return me to a properly working gnome-shell. I can see the desktop background and the top panel (which is responsive). However I cannot access the activities overview, and the Ubuntu dock is missing. One time I noticed that the search field from the activities overview was visible, and it was possible to search for an application. The search did return results, and it was possible to start applications, but they did not show up on the screen. In some cases I could run gnome-shell -r, but this would end the whole session and return me to the login screen.
