I have several issues actually, but I am not sure whether they are related.

1. nvidia-smi out puts no device were found.
2. The system cannot detect the second display.
3. The fractional scaling is not working (can only set to 200% even if I set 150%).
4. The update rate is incorrect in system setting.
