Ubuntu displaying does not correct smootly although I have RTX3060 mobile gpu and installed nvidia drivers

I’ve installed nvidia drivers on Ubuntu 21.04.

But displaying does not works properly. For example

  1. When I log into the system(after I enter password), black screen shows up for two seconds. After that, I can log into the Ubuntu.
  2. Cursor does not move smoothly.
  3. When I open anything it appears after a second.

In addition to them, lshw -C Display shows description: VGA compatible controller product: GA106M [GeForce RTX 3060 Mobile / Max-Q] But ubuntu-drivers devices does not show MODEL.

Please try disabling wayland

I did it but nothing has changed

When I write command echo $XDG_SESSION_TYPE the output is x11

Was just a guess. Please run nvidia-bug-report.sh as root and attach the resulting nvidia-bug-report.log.gz file to your post.
