I have the same issues on my Galago Pro System 76 laptop running Xubuntu 
22.04.1 LTS.

Indeed, my wait is usually 30 seconds or so before I get the screensaver 
login screen again.

The issue seems to be that laptop lid closure is no longer triggering 
sleep in the correct fashion or order, and so the login screen is delayed.

Note that you can Ctrl-Alt-F1 and login to another instance of your 
system. Ctrl-Alt-F7 will bring you back to the frozen display until the 
login screen re-asserts itself.

If I select sleep first before closing the lid, the problem does not occur.

My guess is that it is a bug in the screensaver/login screen.

But, given my workload of late, I have not had time to delve into the 
problem. Instead, I just make sure to select sleep first before closing 
the lid.
