Thank you for taking the time to report this bug and helping to make Ubuntu better.
You've not given details as to your actual install; was it a Ubuntu Desktop 20.04 LTS or Ubuntu Server 20.04 LTS? You do mention moving mouse; a device not normally attached to servers, so I'm assume (rightly/wrongly) you're asking about a desktop system - but it's best if these details are provided. Please execute the following command only once, as it will automatically gather debugging information, in a terminal: apport-collect 1964711 When reporting bugs in the future please use apport by using 'ubuntu- bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

No means of user input (e.g. typing on the keyboard, moving the mouse) produce the lock screen and I have to shut down my computer by pressing down the power button. The attached monitor does not receive a signal from the computer during these attempts. This started to happen several weeks ago and worked without a problem before then. Due to the nature of this issue, I can neither report any errors occurring nor can I observe any other out of the ordinary things from happening. Thus, I don’t know which package is causing the issue. Also, this issue happens every time I leave the computer unattended for a longer time and lock it. However, locking it and triggering an input immediately after does produce the lock screen, so the lock screen seems to work in principle.
