Yes. It is only enabled / working with 6.1 and desktop (Gnome) builds. For mainline based, perhaps 6.18.y ...

@gpupoor You want to set up GPU Acceleration, right? Have you read this post yet?

I've successfully booted Armbian from USB following the tutorial above, and I've managed to write Armbian from the USB drive to the eMMC. Now I want to create an Armbian firmware that can be directly flashed to the H96 M9/S eMMC using RKDevTool.exe, but I'm not very smart - even simple things take me a very long time to figure out. If any of you have this, please share it. If I manage to figure it out, I'll also share my findings.
