How to rotate the screen to vertical?

Hello, I’m building a vertical cabinet usin a raspberry pi 3 and Lakka. How to rotate the gui-text menu? If not possible please add the possibility to do so. Games rotate to vertical with no proble… The menu stays horizontal.

Hi. As far as I know, GUI rotation is not supported in Lakka because that would require using an X server and Lakka uses KMS for that device (which currently does not support GUI rotation).

You would need a custom Lakka build with X server for the Raspberry Pi, so it’s probably just easier to use Raspberry Pi OS desktop + Retroarch for now.
