Switch User makes the screen all black

Environment:

  • Ubuntu 24.04.4 LTS
  • GNOME Version: 46
  • Windowing System: X11
  • GPU: Dual nVidia RTX A5000
  • GPU driver version: 570.211.01

Problem: if I switches user, the screen is all black without displaying user list. Sometimes I am lucky to see the user list displayed immediately, but after I select my user account and input the password, the screen is all black. Is there any way to completely solve this issue? I tried every method ChatGPT gave me, but none of them works, except disabling “Switch User” which I don’t want to.

So, is there any way not to show an all-black screen after I click “Switch User” or input my password? Instead, I wish to see the user list immediately I select a user, and I wish to enter my desktop immediately after I input my password?

GNOME 46 is end of life. Please ask for support on Ubuntu forums.
