I say _should_ as I'm not 100% sure. I'm assuming your device is as below (check the device IDs with 'pci -nn'): [10de:11b6] NVIDIA Corporation GK104GLM [Quadro K3100M] That device was previously listed as supported: https://download.nvidia.com/XFree86/Linux-x86_64/410.66/README/supportedchips.html but I can't find it listed on the currently supported chipset's page, hence my doubt: https://download.nvidia.com/XFree86/Linux-x86_64/460.67/README/supportedchips.html I'd be interested to know which driver version NVIDIA pointed you towards? >> >> What I did was shift my workstation install to the elrepo kernel-ml >> kernels (you might want kernel-lt .. it is latest long term kernel).

As Johnny says above, if you use a different kernel, such as those from elrepo, you will need to install the driver directly from NVIDIA. Regards, Phil
