Hello,
Every once in a while (about 1/100) vt switches will crash the nvidia driver and the whole graphics stack along with it.
The system is then wholly unresponsive but not dead (somtimes, you can reach ssh, and things still get printed to the log), however the display totally freezes, and you basically have to reboot.
I am using Prime render offload on my notebook. Since closing and opening the lid causes two VT switches internally, this bug appears more often than I would like it to. It has only started appearing with prime, before (when I only used the internal GPU) it did not happen.
The log around the crash looks like this:
