Configurar o xorg (modo gráfico) para utilizar o display [Opcional]

Procurar a linha onde tiver /dev/fb0 e substituir por /dev/fb1

# sudo nano /usr/share/X11/xorg.conf.d/99-fbturbo.conf

Iniciar o modo gráfico no display [Opcional]

FRAMEBUFFER=/dev/fb1 startx &

Calibrar o Touch [Opcional]

xinput_calibrator

já está funcionando no Raspberry Pi 2?

sim, esse guia serve para raspberry pi 1 ou 2.

http://www.circuitbasics.com/setup-lcd-touchscreen-raspberry-pi/

Valeu @zottoz. Tinha feito esse guia já a um tempo atrás e vi que estava desatualizado, acabei de testar tudo novamente e agora está ok.

Tive um problema ao Editar os parametros de inicialização do sistema, ao reboot da maquina, apresentava esse erro:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,2).

Dai eu alterei parte da linha onde tem "root=/dev/mmcblk0p2", eu alterei para "root=/dev/mmcblk0p6"

Senhores,

Testei o guia e aparentemente funciona. Mas tem algo estranho acontecendo, quando usa-se o touch, seja com o stylus ou com o dedo, acontece algum problema na rederização do X. O cursor anterior não apaga, o lcd fica todo blocado e em algumas regiões as cores se invertem. Nesta condição, se mover o mouse tudo se ajeita e o lcd volta ao normal.
Será que é alguma interferência no SPI?
Neste momento estou fazendo upload de um vídeo ( http://youtu.be/HpOzN5wFeho ) que mostra o problema acontecendo.
Estou usando o Raspberry 2 com raspbian baixado ontem do site oficial (kernel 4.0.7-v7)
