After a recent upgrade on a RPi4 I noticed that fkms does not work anymore, searching raspberry forums it seems that fkms is depreciated. How can I get a list of supported modes from my monitor? I'm running kodi-standalone, so no GUI involved.
/opt/vc/bin/tvservice -m DMT used to do the trick but using kms it says:
/opt/vc/bin/tvservice is not supported when using the vc4-kms-v3d driver.
Similar features are available with standard linux tools
such as kmsprint from kms++-utils
How do I install kms++-utils on Arch ARM?
