Ubuntu 22.04.3 LTS on Hyper-V (Windows 11 Pro) Enhanced session not working

[kalpana]

Hi,
I have this fully updated Ubuntu Pro installation, but I'm not able to adjust the display settings on the Hyper-V virtual machine.
The VM is "Generation 2", so it should work from the Hyper-V side. It works fine with the other Microsoft VM's.
The Ubuntu "Screen display" settings are also locked at 1024x768 (4:3) and showing "Unknown Display".
Is it something with the integration services? If yes, then what can I do?

Thanks.
