@Yuan-Chen, no I have not installed other versions of Nvidia proprietary drivers with Ubuntu on this PC.
If you want I can try to install on a partition of my hard drive previous versions of Nvidia drivers on Ubuntu 18.10 (now I have a partition with Ubuntu 18.10 newly installed). If needed I can install another version on Ubuntu and Nvidia drivers.
I had installed Nvidia drivers just for a call for testing as I had the graphic card.
