My daughter just got the PiTFT for her Raspberry Pi, and I finally picked up myself a Pi(B+, woo woo)+touchscreen as well.
Given that she's in second grade and I think every other kid in school plays Minecraft, she was extremely excited when she realized it was preloaded on her Pi.
However, when she launches it the main minecraft window (with the decorations) shows up on the TFT nice and black. But the actual minecraft display shows up out of the HDMI. We've tried export FRAMEBUFFER=/dev/fb1
a la the Adafruit guide in console and then running minecraft-pi
but alas! No luck. The minecraft game window still goes the wrong direction.
So, how can we make Minecraft show up on the PiTFT?
