PiTFT Mini Kit switch over to HDMI
hello and this is a quick question about the 2.8" PiTFT Mini Kit https://www.adafruit.com/product/1601 and the reason i ask is that i have one. i have successful installation and was woundering how could i switch over to HDIM and back to the PiTFT Mini Kit screen i know that it could display one thing at a time i am just curious if there is a button or command i type in and would change between the screens and if so could you please respond back thanks

This doesn't seem to work when using the B+ model with the pitft. No idea why.

Re: PiTFT Mini Kit switch over to HDMI
OK we'll take a look! Can you be specific about what doesn't work, what output you get, etc? whether you are using an image (and which one) or installing the debs...

I'm just using the plain vanilla beta image from the tutorial page.
Both FRAMEBUFFER=/dev/fb0 and FRAMEBUFFER=/dev/fb1 put the X gui on the PiTFT.

Yep, that works for me. I still get the touchscreen calibration on the HDMI, which is a little weird, but it times out eventually.

Re: PiTFT Mini Kit switch over to HDMI
