Ubuntu Version: Ubuntu Desktop 24.04.3 LTS Desktop Environment (if applicable): Default env Problem Description: This is my development box. I’ve been using it for a long time. I run various GPU tasks on it, such as PyTorch code, LLMs, etc. Yesterday, I did apt-get update; apt-get full-upgrade as I always do at the end of the day. I noticed it did some NVIDIA updates. Then I rebooted into Windows. Later, I booted Linux again. Then I noticed all GPU support was gone. Anything requiring GPU …

That’s my dev box. The GPU worked great for a long time until yesterday, when a new driver version was installed by apt-get full-upgrade and it broke the GPU support.
