[Bug 2141416] [NEW] External monitor no longer detected (nvidia)

Public bug reported:

For some week my external monitor does not work anymore. In gnome-
settings in displays, I have no second display available.

The kernel shows on start-up:

```
kernel: NovaCore 0000:01:00.0: Unsupported chipset: boot42 = 0x117a2031 (architecture 0x11, implementation 0x7)
