# Validation — Checks rapides
|
|||
|
|
|
|||
|
|
## 1) Driver / GPU
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
nvidia-smi
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Attendu :
|
|||
|
|
|
|||
|
|
- La RTX 5070 Ti est listée
|
|||
|
|
- “Driver Version” correspond au driver installé via Ubuntu
|
|||
|
|
|
|||
|
|
## 2) CUDA Toolkit (version installée)
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
which nvcc
|
|||
|
|
nvcc --version
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Attendu :
|
|||
|
|
|
|||
|
|
- `which nvcc` → `/usr/local/cuda-12.8/bin/nvcc`
|
|||
|
|
- `nvcc --version` indique CUDA 12.8
|
|||
|
|
|
|||
|
|
Note :
|
|||
|
|
|
|||
|
|
- “CUDA Version: …” dans `nvidia-smi` n’est pas la version du toolkit installé ; c’est la capacité exposée par le driver.
|
|||
|
|
|
|||
|
|
## 3) APT anti-régression (pinning effectif)
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
apt-cache policy libnvidia-gl-580 libnvidia-egl-gbm1 nvidia-driver-580-open nvidia-utils-580 | sed -n '1,220p'
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Attendu :
|
|||
|
|
|
|||
|
|
- Les candidats `nvidia-*` / `libnvidia-*` proviennent d’Ubuntu
|
|||
|
|
- Le dépôt CUDA NVIDIA apparaît, mais ne “gagne” pas pour `nvidia-*` / `libnvidia-*` (pinning actif)
|
|||
|
|
|
|||
|
|
## 4) Upgrade propre
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
sudo apt update
|
|||
|
|
sudo apt upgrade -y
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Attendu :
|
|||
|
|
|
|||
|
|
- Aucun conflit `libnvidia-gl-580` ↔ `libnvidia-egl-gbm1`
|
|||
|
|
- Aucun paquet cassé / retenu pour cause de dépendances NVIDIA
