Ubuntu 18.04 Driver Installed. Using llvmpipe only

Graphics / Linux Linux

Hi,

I just recently switched from AMD to NVidia. I removed AMD drivers. Installed NVidia drivers successfully though was system froze at login screen

Changed /etc/default/grub to include nvidia-drm.modeset=1. Login was successful though froze once credentials were entered.

I was able to login successfully to the desktop after changing to wayland but system is only using llvmpipe

Here is the output from terminal. Happy to provide any further info

    GLX_EXT_visual_rating, GLX_MESA_copy_sub_buffer, GLX_MESA_query_renderer,

The nvidia driver currently only supports software rendering (llvmpipe) when used in Xwayland.
Using Xorg, you were running into permission problems on login. Please post the output of
ls -l /dev/nvi*
ls-l /dev/dri/*
Please try adding your user to the video group.

Thanks generix for the response.
Below is the output though looks like my account is already part of the video group

Can you please check if disabling the integrated intel gpu changes anything?

Unfortunately I do not have the option to disable it via the BIOS.

Which other way can I disable it?
