The nvidia gpu is intermittingly hanging but I don’t know the cause for this. Is some driver bug that’s happening on some hardware. Please check if you can work around it using on-demand mode of prime-select.

Hey! It seems that whenever I enable secure boot my graphics driver stops working!
Can you suggest something for it or why is this happening?

You installed the driver using the runfile installer, this shouldn’t be used ad will break anyway on kernel update since you didn’t use dkms. Please uninstall and use “Software&Updates” to install the driver from Ubuntu repo.
In general the driver isn’t signed, so will fail to load when secure boot is enabled. So you will either have to enable module signing or install the signed driver version from repo.
The easiest way to do this is reinstall Ubuntu with secure boot enabled and choose “Install Third-Party Software” during install. Changing this in the running system either involves using ubuntu’s update-secureboot-policy or changing driver sub-packages manually.
