Black Screen on Ubuntu20.04 after login

I have a black screen after I do apt update with Ubuntu 20.04. It is ok before the login screen, but after I enter the password and login, the screen goes balck. I can only login via ssh.

I am using an GTX 1080 gpu, I’ve tried solutions for similar problem on this formus, but still not working.

here is my nvidia-bug-report:nvidia-bug-report.log.gz (316.4 KB) Thank you!

According to the logs, the Xserver is working fine after login. Please try this:

  • log in on text console, then run
    rm ~/.config/monitors.xml
    and reboot.
  • If that doesn’t help, try creating a new user and log in as that to rule out a broken user profile.

Thank you so much! That works!
