Ubuntu 20.04 driver 440 installed but not used

Hello, I have a laptop with an RTX2070 and i7-10750H CPU running Ubuntu 20.04, driver version 440.64 installed but it seems I cannot use my GPU. After trying many things from this forum I am in this state :

  • Prime installed and nvidia profile is selected
  • Kernel 5.4.0-31-generic
  • Secure boot seems disabled
  • I removed blacklist files in /etc/modprob.d/ and /lib/modprob.d and there is no xorg.conf file in /etc/X11/
  • /lib/modprobe.d/nvidia-graphics-drivers.conf contains : blacklist nouveau \ blacklist lbm-nouveau \ alias nouveau off \ alias lbm-nouveau off
  • nvidia-settings and nvidia-smi confirms the driver is installed but I have no nvidia driver at all in the “Additional driver” window of the software update. (I added the graphic drivers ppa). There are only the intel cpu driver choices
  • ubuntu-drivers devices outputs nothing or just the intel driver.

I have also tried it with ubuntu 18.04, same results, it is still installed in dualboot.

Additional information, I am trying to use the GPU to run the lgsvl car simulator.

sudo lshw -c video outputs this :

I am using only using the laptop screen.

According to the log, the nvidia gpu is fully functional and active. Please run
glxinfo |grep vendor
to confirm, should return"nvidia corporation".
