+Après l'installation vérifier dans ''/etc/modprobe.d/nvidia-graphics-drivers-kms.conf'' que ''options nvidia_drm modeset=0'' car par défaut il est à ''1'' et donc Xorg aura un process dans la RTX, visible avec ''nvidia-smi''.

-        NVRM: has the version 590.48.01, but this kernel module has
-        NVRM: the version 595.58.03.  Please make sure that this

-        NVRM: kernel module and all NVIDIA driver components
+  * 🚀 Quelques questions dans le chat de llama.cpp : Ok
-        NVRM: have the same version.
+  * 🚀 Refactoring de code avec ''opencode'' et le modèle ''gpt-oss-20b-UD-Q4_K_XL.gguf'' : Ok
