I had several of these extensions. I started by disabling them all. This fixed the problem (thanks!). I then re-enabled most of them one at a time (because they are all things I find extremely useful—I do not like to install extensions unless I have to!).
In the end, I was able to reinstall all but one of the extensions I need, namely 'cont...@projecthamster.org' I had no problem with: 'nohotcor...@azuri.free.fr' 'switc...@landau.fi' 'topIcons@adel.gadl...@gmail.com' 'windowIsReady_Remover@nunofarr...@gmail.com' 'windowoverlay-ic...@sustmidown.centrum.cz' 'window-search-provi...@quelltexter.org' I am interested in how you made the list, @vanvugt; is there some reason to suspect the other extensions listed are problematic too? In any case, my immediate problem seems to be solved (thanks very much), and I now need to find a fix for using Project Hamster, as I rely on it to time work. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1812373 Title: Desktop is not restored correctly after screen saver Status in gnome-shell package in Ubuntu: Incomplete Bug description: With the update to 3.28.3-0ubuntu0.18.04.4, on two separate machines, the screen saver stopped working properly. When the screen is locked manually (by clicking the lock screen icon), the screen either freezes with the desktop still showing, or shows the same grey background as the login screen; it does not show the normal lock screen image. When the screen saver is activated automatically, the screen turns off as normal, but when I press a key, the grey background as for the login screen is shown (in fact, it's the same as the login screen, but without the login widget; that is, the normal icons are shown at the top of the screen). Pressing Ctrl+Alt+F1 switches to the login dialog. I can then log in successfully, but all GNOME shell extensions are disabled. (A simple workaround is then to restart gnome-shell with the "r" command from the "Enter a command" dialog.) I am marking this bug as a security vulnerability because in the case that the screen simply freezes, confidential information may be displayed by the failure of the screen shield to activate.
