PS: just tested with latest vanilla kernel 5.7.9-050709-generic from https://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D, things work. It seems there's some issue with 5.4.0-40-generic.

When the desktop recovered, I looked at dmesg logs to find these lines: [ 461.937702] NVRM: GPU at PCI:0000:01:00: GPU-734060ac-116d-fbbb-1553-d84896b846a4 [ 461.937710] NVRM: Xid (PCI:0000:01:00): 31, pid=275, Ch 0000002e, intr 00000000. MMU Fault: ENGINE HOST0 HUBCLIENT_HOST_CPU faulted @ 0x1_0036d000. Fault is of type FAULT_PTE ACCESS_TYPE_VIRT_READ It looks like a fault from the Nvidia driver. I'm using the tested one "nvidia-driver-435", installed via the GUI tool. Could you report this to Nvidia please ?
