Rpi5 core-image-sato requires /etc/X11/xorg.conf.d/99-vc4.conf file for GUI to appear (not needed for Rpi4...)

[PSkeberdis]

Used yocto/poky and meta-raspberrypi "nanbield" branch to build core-image-sato for MACHINE?= "raspberrypi5".

(as an aside, had to increase boot partition size by adding BOOT_SPACE = "61440" in local.conf to create sd_image...)

Made an SD card and booted Rpi5 - the xserver fails, and the GUI does not appear as expected, and boots to console to login.

After searching for solutions, found the following:
Add below configuration to a file named 99-vc4.conf and save to /etc/X11/xorg.conf.d/ directory:

Section "OutputClass"
  Identifier "vc4"
  MatchDriver "vc4"
  Driver "modesetting"
  Option "PrimaryGPU" "true"
EndSection

Following reboot, the xserver succeeds and the GUI appears as expected.

Seems like this /etc/X11/xorg.conf.d/99-vc4.conf should be added to the recipe.

Greetings everyone!

Was someone able to configure rotation of the screen? I can't find a way to do it over x11.

Here I'm having issues with xrandr returning xrandr: Failed to get size of gamma for output default.
