drivers – Ubuntu installation stop working in 1 day, What could be reason?

Yesterday I installed 20.10 into my local pc and things were working fine. I install NVM (node version manager) and shutdown the laptop.

Today when I start first I see touch is not working. internet is not working. When I run Firefox it’s run on low GPU. I see the resolution, it’s 1024*786.

What could be the reason for this. I didn’t change anything. Just choose the Nvidia (455,proprietary,tested).

Any help, I have installed the ubuntu again. Anyone any idea what could be the reason for this.

Thanks
