The story of replacing Nvidia GTX 1650 with Linux Mint 20.1.

Origin

The other day, I installed CUDA on Linux Mint 20.1 and now I'm eager to restart GPGPU ... it doesn't work. Entering nvidia-smi from the terminal is an error. The driver doesn't seem to work. I was using the old GTX960. Maybe it's not supported anymore? At this time, I replaced it with GTX1650. After some trial and error, CUDA is now working. I will record it for a later date.

Originally, it is a game machine called Galleria made by Dospara. I bought it to try GPGPU. When I consulted with a Dospara clerk, it seems that there is no particular problem with replacing it with the GTX1650. I bought AERO ITX1650 made by msi. It was about 15,000 yen. The auxiliary power supply was the same as the GTX960 and was OK. The size of the 1650 is smaller, and it fits comfortably on the board.

Driver installation

The problem was the software. The following steps will work.

〇First, install Linux Mint 20.1 by USB boot normally. Then reboot and start working.

〇 The first thing to do is to connect to the Internet. Without this, you will not be able to get the driver. In my case, it's a wired connection, so I connected to the net while looking at my previous article. https://qiita.com/sym_num/items/cfb32a3841721eed98e4

〇 Execute sudo apt update sudo apt upgrade from the terminal. It will take some time. It took about 20 minutes. On the way, the following screen will be displayed. Enter the password twice for secure boot.

〇 Call the driver manager from the menu. Initially, the situation is as follows.

〇 Reboot Change this to the recommended 460. And reboot. From here is important. Secure boot. Select with the arrow keys on the screen as shown below to proceed. If you do not do this and simply proceed, the driver will not be installed correctly. You will be prompted to enter the password on the way. This is what you entered when you upgraded. No echo is displayed.

〇 Confirmation After restarting, check again with the driver manager. It has been changed to the recommended 460 correctly.

〇Replacement When you reach this point, turn off the power. Remove the GTX960 board and replace it with the GTX1650 board. Don't forget to connect the auxiliary power plug.

〇 Power on This should work ... but the screen remains black and I can't move on. Isn't it funny? Once, the power was forcibly turned off and restarted. This time it worked correctly.

〇 CUDA installation The rest is the installation of CUDA. Please refer to the following article. https://qiita.com/sym_num/items/557f2a17eda5e2c90706
