Starting to program for Cuda do I have to load the drivers

Hi there
new to julia and cuda. Have loaded Linux Mint 20.2 and using the OPENSOURCE drivers for a Nvidia k5000 board.

Graphics:  Device-1: NVIDIA GK104GL [Quadro K5000] vendor: Hewlett-Packard driver: nouveau v: kernel 
           bus ID: 04:00.0 chip ID: 10de:11ba 
           Display: server: X.Org 1.20.11 driver: modesetting unloaded: fbdev,vesa 
           resolution: 3840x2160~30Hz 
           OpenGL: renderer: NVE4 v: 4.3 Mesa 21.0.3 direct render: Yes

I have loaded and tested julia on the machine. Do I need to load any software from nvidia OR does Julia load everything I need?

thanks in advance

ARGGH how embarrassing!!! If it wasn’t in the first few lines I would have an excuse.

The Julia CUDA stack only requires a working NVIDIA driver;

thank you so much for taking the time to help someone who clearly has lost the plot.
I was hoping that I wouldn’t have to use the nvidia 470 drivers for linux mint as the resolution only goes up t0 1920 1080*

Whereas the OPENSOURCE goes up to 3840x2160~30Hz

This answers my question. Have an excellent one.

fixed it. Added a plugable dp active adapter to a hdmi cable. Changed the drivers to nvidia 470 and all is well. I have 4k resolution now and official drivers.
thanks so much for you help @jling
