The NVIDIA 50-series Blackwell cards require the use of the new open GPU kernel module, but several of NVIDIA’s older generations of GPUs - including the Maxwell, Pascal, and Volta generations - lack the GPU System Processor (GSP) module on their silicon in order to leverage the open kernel module, and thus will no longer function. This includes the GTX 700-series, 900-GTX series, GTX 10-series, the Quadro M-series and P-series, and Tesla M-series and P-series cards.
Here’s the detail. Sounds like the support for the new cards messed up the old cards, but it sounds like they might be working on a comparability fix. I use open drivers on some other systems. I don’t remember why I didn’t consider that a option here. This server has lived many lives and it’s mission continues to change and refocus all the time. Thanks for the reply.



Here’s info on what’s up and the workaround if you still want to. You may have an easier time than me if you have more experience with this sort of thing.
