I run ubuntu-bug gnome-shell in a terminal but not in wayland, do I have to repeat it there?

Thanks for the bug report. It looks like the system can't find a working graphics driver and so it's using slow software rendering.

Please run:

  lspci -k > lspci.txt
  journalctl -b0 > journal.txt
  dpkg -l > allpackages.txt

and attach the resulting text files here.

Thanks for the quick reply.

The problem here is that kernel 5.13 and the free graphics driver it includes is too old to support your Nvidia RTX 3060 Ti chip.

Please use the 'Additional Drivers' app to install the official Nvidia driver.

summary: - ubuntu on wayland works very slow

Alright, now there is no option for login with Ubuntu on Wayland, but maybe this have solved my previous xorg problem.

Wayland will be an option again in Ubuntu 22.04 but you can enable it manually by adding a kernel parameter: nvidia-drm.modeset=1
