(Thanks to everyone who is taking the time out of their day to look into this.)
I think I should note that I can't replicate this issue reliably. It happened "at random" and it didn't happen again since I filed this report. It's just that it wasn't the first time it happened and I saw others have similar issues. That is why I reported it. Again I want to preface that the extensions shown in the list are the once which came pre-installed with Ubuntu 18.04 (iirc) and I never touched them. (I have some indicator apps but I assume you don't mean them.) I also don't understand why I should disable stock Ubuntu extensions that provide basic functionality like the dock. Would you consider disabling the dock a solution or do you simply try to pin down the culprit? With that said I can explain the seemingly contractionary pictures. The gnome Tweaks app shows a wrong state. The extensions app shows the correct state. Screenshot attached. This must be a bug in gnome Tweaks. The gsettings file shows something interesting: According to the file I have two extensions active that I can't remember ever installing and that do not show up anywhere: org.gnome.shell enabled-extensions ['update-extensi...@franglais125.gmail.com', 'move_cl...@rmy.pobox.com'] File attached. Could it be that there are extensions active that I or someone living with me installed in the past but don't show up in the extensions settings? If yes how do I remove them for further bug testing? ** Attachment added: "Screenshot from 2020-06-11.png" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1882353/+attachment/5383086/+files/Screenshot%20from%202020-06-11.png -- 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/1882353 Title: Ubuntu Dock and Top bar accessible from lockscreen Status in gnome-shell package in Ubuntu: Incomplete Bug description: This is a very serious security issue: When I lock my desktop with SUPER (windows) + L my screen gets locked and goes to black. Sometimes when I return to my PC and move my mouse to turn my screen back on I notice that the Ubuntu Dock + the Top Bar are accessible from the lockscreen. I unfortunately can't remember if they were accessible from the moment I locked the screen or became accessible after returning from fade to black. (This is not the first time this issue happened.) I was able to open the settings menu from the top bar and use all indicators. You can actually start the programs in the Ubuntu Dock and give keyboard inputs to them. For example I was able to start the terminal emulator from the lock screen and run firefox and other applications. So an attacker could run arbitrary commands with user privileges from the lockscreen! The indicators drop down menus were fully visible on the lock screen while the Dock applications remained hidden "behind" the lockscreen (however still accessible via keyboard as described above). I have attached a screenshot of the bug. I unfortunately had no camera at hand to film me running terminal commands. Please contact me if you need additional information.
