Dear all,
I have a similar issue as reported in Ubuntu 20.04.4 - driver fails and other reports where only one monitor worked after driver installation.
I tried several options recommended in the mentioned discussions but I am still having an empty NVIDIA X Server window.
After I changed to kernel 5.10 the output of my nvidia-smi shows the usage of the recommended nvidia-driver-515:
