Ask Ubuntu Asked by Yehuda on December 16, 2020
I am running Ubuntu 20.04 an ASUS TUF A15 with an NVIDIA GeForce GTX 1660TI GPU. According to NVIDIA, the driver version for this GPU is 430. When I first installed Ubuntu, I installed 440. I’m now trying to correct that and install 430.
I ran sudo apt-get install nvidia-driver-430, and then did a reboot. When I examined nvidia-smi, though, it still showed the 440:
+-----------------------------------------------------------------------------+
| NVIDIA-SMI 440.100 Driver Version: 440.100 CUDA Version: 10.2 |
|-------------------------------+----------------------+----------------------+
| GPU Name Persistence-M| Bus-Id Disp.A | Volatile Uncorr. ECC |
| Fan Temp Perf Pwr:Usage/Cap| Memory-Usage | GPU-Util Compute M. |
|===============================+======================+======================|
| 0 GeForce GTX 166... Off | 00000000:01:00.0 Off | N/A |
| N/A 55C P0 9W / N/A | 0MiB / 5944MiB | 0% Default |
+-------------------------------+----------------------+----------------------+
What is the appropriate way of updating this driver?
In Ubuntu it doesn't matter what the NVIDIA website says. It matters what the results of ubuntu-drivers devices are. Ubuntu is bundled with a tool named ubuntu-drivers which detects and installs proprietary graphics driver packages. It detects proprietary graphics driver packages with ubuntu-drivers devices. The sudo ubuntu-drivers autoinstall command replaces all the unnecessary guesswork by automatically installing the correct proprietary graphics driver packages if there aren't any proprietary graphics packages currently installed.
