I posted this on the NVIDIA forums, but thought it might be helpful to
cross-post here.

I just tried the 460 server driver solution. This did not work for me
and I still have the display port bug.

I have an AMD 3800X, 64 gb ram, rtx 2080 super, fresh install of Ubuntu
20.04 kernel 5.8.0-55, with 3 identical 4K monitors, (1 on HDMI, 2 on
DP). The opensource driver continues to work just fine, but we need CUDA
for our science to continue.

Here are the outputs from nvidia-smi, uname -r, and xrandr. Note that
all monitors should have 4K options.

I tried the nvidia-driver-460-server solution. Sadly it did not work for
me.

The display port connected monitor resolutions are not correct with the
460.73.01 driver version showing 1080p when they should be 4K.

  Jun 03 16:26:57 willow kernel: Fixing recursive fault but reboot is needed!

  
  switching to a tty or login with ssh does not work at that point.

  Installing the nvidia-driver-450-server from advanced mode got me a
  desktop back.

  I found this upstream bugreport:
  https://forums.developer.nvidia.com/t/465-24-02-page-fault/175782/62

  where people on different distributions have this problem, and it
  might be related to DP. My monitor is connected with DP.

  From lspci:

  01:00.0 VGA compatible controller: NVIDIA Corporation GP107 [GeForce
  GTX 1050 Ti] (rev a1)

  I also have a laptop with a 1050ti where I can use these drivers on
  21.04 without problem, while only the inbuilt screen is connected. I
  will try the laptop with DP, and my desktop with HDMI later
