@alan_g Ubuntu server 20.04 supports raspberry pi GPIO? Because in docs they have mentioned it will work in Ubuntu server 21.04 with kernel version 5.11.
all ubuntu Pi kernels have always supported GPIO the same way they are supported by the pi foundation kernels in the respective version … this is not really relevant for ubuntu-frame (mir-kiosk) on the pi though, you should open a new thread for such things …
