After upgrading to current OSMC release, I was surprised the “tvservice” is not working anymore.
I get this error message:
tvservice is not supported when using the vc4-kms-v3d driver.
Similar features are available with standard linux tools
such as modetest from libdrm-tests.
Is there any new command to get a similar functionality?. I miss a lot being able to check that videomodes a particular TV supports, for instance.
