X11 forwarding broken following Quadro driver update

we have a system that has a Quadro P6000 installed. This system also has two Variable Action Button (VAB) panels on it, that is sent an X11 window from a java app that display the buttons on the VAB.

The system runs RHEL8 (but also found this same problem on RHEL7) that if we update the NVIDIA driver from 460.73.01 (which isn’t even for the _6000 card) to anything that is for the 6000 card, we get no display on the VABs.

What I’ve realized is that when the java app runs and tries to send that display, the lightdm service on the VABs stop.

Can anyone offer any theories as to why that might be?
