[nvidia] PC doesn't send signal to the second monitor using nvidia-470 (but nvidia-460 works)

[Artem Mikhalev]

After turn on mu PC, it doesn't send signal to the second monitor. (with driver "nvidia-driver-470(proprietary tested)"
After change it to: "nvidia-driver-460(proprietary)" problem solved.

Looks like new kernel update have conflict with nvidia - 470 driver. (because yesterday it was fine but today is broken, and made me to change the driver)

[Artem Mikhalev (muhadroid)]

Sending this bug after, solved by change drivers, i can change it back to 470, and perform debug commands if needed (gather logs etc.)

[Daniel van Vugt (vanvugt)]

Please collect logs from the failed boots of the 470 driver by running:

  journalctl -b-1 > prevboot-1.txt
  journalctl -b-2 > prevboot-2.txt
  journalctl -b-3 > prevboot-3.txt
  journalctl -b-4 > prevboot-4.txt
  journalctl -b-5 > prevboot-5.txt

and attach the resulting text files here.
