📝 Provide a clear and concise description of the issue.

script fails in misc/tools.func during GPU setup. It tries to identify the driver version number with:
nvidia_host_version=$(grep -oP '\d{3,}.\d+.\d+' /proc/driver/nvidia/version 2> /dev/null | head -1)
which is aiming at a driver version pattern of xxx.xxx.xx while newer drivers (like 580.142) just only have the pattern xxx.xxx.

🔄 Steps to reproduce the issue.

just do a default or advanced installation
