Cant set 120hz on Ubuntu 25.04. The option does not show in screen display settings.
Setup:
In previous NVIDIA driver, I was able to modify the refresh rate to 120HZ via Nvidia Settings but the screen would appear black and rollback the change.
AFAIK, the screen and graphics card both support this?

Hi, would you mind retesting with 580.119.02?
Installed 580.119.02. Attached new bug report.
NOTE: Cannot seem to force 120hz through UI or nvidia-settings.

@rrameshbabu any ideas on this one?
Sorry for replying so late. This somehow missed my inbox.

The above is the decoded EDID from the logs. I do not see a 4k 120Hz mode but I do see a 5k 120Hz mode.
It also looks like nouveau is not blacklisted and the X11 nouveau driver is driving your display, rather than the NVIDIA driver.

You will need to blacklist the nouveau kernel module from loading for the NVIDIA GPU to behave correctly. This log capture may not be accurate though/maybe taken in a bad state. What desktop environment are you using and is it X11 or Wayland based? Thanks in advance.
Thanks @rrameshbabu, disabling the nouveau driver fixed the issue. Can now run 5K @120Hz.
Ah, so it was the nouveau driver. I edited my answer because the logs were quite messy for me to confirm.
