J’ai trouvé : https://github.com/TwinkleByte/nouveau-smi  

Installation :

# apt install golang-go
# git clone https://github.com/TwinkleByte/nouveau-smi.git
# cd nouveau-smi
# go build -o nouveau-smi ./cmd/nouveau-smi/main.go
# sudo install -m 755 nouveau-smi /usr/local/bin/
# nouveau-smi 
 Error: could not find hwmon directory for nouveau driver
# apt install psensor
# nouveau-smi 
 Error: could not find hwmon directory for nouveau driver

Visiblement il cherche /sys/class/hwmon .

J’ai essayé la commande :

# sensors 
No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.

# sudo sensors-detect

Sans succès … surement car c’est une VM sous Proxmox .

# inxi -F
