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

Title:
Locked Ubuntu is frozen and cannot be unlocked
Status in gdm3 package in Ubuntu:
New
Bug description:
After locking Ubuntu and leaving it unattended for a while, the
operating system cannot be unlocked anymore. 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.
Description: Ubuntu 20.04.4 LTS
Release: 20.04
