Below is a quote from an Adafruit forum ( of a discussion I had about the 3.5" capacitive touch screen they sell, which is very similar to the 2.2" screen discussed here.

I don't really understand why it is so impossible to get a small capacitive touch screen to work with Arch/Rune Audio, especially since (1) at least one resistive touch screen works (Tontec), although touch responsiveness is very poor, and (2) the official Raspberry Pi 7" screen works.

At this point, I'm almost willing to pay someone to either make one or do the software modifications necessary to make the existing capacitive touch screens work.

With the all-in one image is the PiTFT 3.5" working but i donĀ“t want to use the raspbian image.
Is it possible to get the TFT working for other distributions?

I understand that Adafruit does not support other distributions, but are you saying that it is absolutely impossible for anyone to get the PiTFT Capacitive touch screen to work on any other distribution, in particular Arch Linux? even on the RPi2? What is it about the PiTFT that makes it incompatible with all distributions other than Raspbian?

while it is technically possible (its a kernel/module update) and Kali for sure has added the kernel - nobody that we know of has done it for other distros and its apparently not trivial! we've never used arch so we dont even know what is required.

In case anyone is interested, I got a 3.5" resistive display working: ... 38#p811038
