ubuntu 20.04 nvidia stuttering

[Muhammad Dhia R]

Wasn't sure if this is a bug, but here's my problem.

I was using ubuntu on my laptop while connecting HDMI cable to a Smart TV.

On the tv display, I was watching a video and on my laptop display I was browsing.

And then I need to check google maps for direction, and suddenly...

My laptop freezed and I had to hard shut-down.

And when I reboot, my ubuntu is still stuttering until now.

I'm hoping here someone has an idea of what's going on and what is the solution, if possible.

Thanks for the bug report. While the stutter is still happening, please run:

  lspci -kv > lspci.txt
  journalctl -b0 > journal.txt

and attach the resulting text files here.
