-> Detected 12 CPUs online; setting concurrency level to 12.
-> Installing NVIDIA driver version 435.21.
-> There appears to already be a driver installed on your system (version: 435.21).  As part of installing this driver (version: 435.21), the existing driver will be uninstalled.  Are you sure you want to continue? (Answer: Continue installation)
-> An alternate method of installing the NVIDIA driver was detected. (This is usually a package provided by your distributor.) A driver installed via that method may integrate better with your system than a driver installed by nvidia-installer.

Please review the message provided by the maintainer of this alternate installation method and decide how to proceed:

The NVIDIA driver provided by Ubuntu can be installed by launching the "Software & Updates" application, and by selecting the NVIDIA driver from the "Additional Drivers" tab.


(Answer: Continue installation)
-> Would you like to register the kernel module sources with DKMS? This will allow DKMS to automatically build a new module, if you install a different kernel later. (Answer: Yes)
-> Install NVIDIA's 32-bit compatibility libraries? (Answer: Yes)
-> Uninstalling the previous installation with /usr/bin/nvidia-uninstall.
