Debug Nvidia POP OS
Testing: glmark2
sudo apt install system76-driver-nividia

nividia-384
This is the correct apt package to install.
The problem is most likely that POP OS updated the kernel.
Reboot and hold shift to switch to an older kernel.
Try uninstall the nvidia drivers and reinstalling in the older kernel.
