Boot splash screen shows in landscape instead of portrait

device
1

Hey, we have a device that is used in portrait mode, and we have our own ubuntu core 22 images(gadget, etc), we would like to add splash screen so that the user won’t see booting logs, i have managed to add a splash screen, but what happens is when the device is booting it boots as landscape mode.

Is there a way to rotate the display at boot? I was expecting this to be possible through kernel command line parameters passed via our custom gadget.

I tried the following, but it didn’t work:

kernel-cmdline:
  allow:
    - video=rotate=90

Hey @ogra, saw you were involved in this topic(splash screen) in the past. Do you have any input for us?

Thanks
