Public bug reported:
Missing VTs in kernel 5.15.0-22-generic (but 5.15.0-18-generic works).
Steps to reproduce:
1. Boot Ubuntu.
2. Press Ctrl+Alt+F4.
Expected: VT to be displayed
Observed: Monitor turns off.
Notes:
* This failure only happens in 5.15.0-22-generic. Kernel version
5.15.0-18-generic works fine.
* I am currently using the nvidia-470 driver in case that's relevant.
