I can add my 2 cents about this bug: I discovered that once this bug happens one of solutions is to leave it as it is and wait until screensaver starts. Then when you resume everything is almost normal - you have login screen and after entering password you have normal desktop. So it looks like kind of timeout which ends and gnome-shell starts. But I mentioned that it almost normal - I mean that after these steps you have normal desktop but actions are very limited, there is no response for mouse clicks etc. So you need to reload gnome-shell with Alt-F2+r and then everything is 100% ok. I hope it may help to diagnose this bug a bit.

Now whenever I log in, sometimes I'll get a blank screen. It will only show the mouse cursor as an X. The problem seems to be intermittent. So far it's only happened to me using X11. My current workaround: 1. Open another terminal (e.g. Ctrl+Alt+F6) 2. Restart gdm3 (sudo systemctl restart gdm3) This seems to be affecting many people, although I couldn't find an existing bug: https://askubuntu.com/questions/1514757/issue-with- ubuntu-24-04-black-screen-with-cursor-on-login $ lsb_release -rd No LSB modules are available.
