(I, err, never actually tried fbdepth on a Kindle, but I *should* have hidden the NTX quirks behind ifdefs  ).
Every Kindle since the K5 (and the K4, technically ) will support the actual PxP inversion this requests (by which I mean to say that the only things missing on the KT4 are the fancy waveform modes and the fl shenanigans).
@yparitcher: strace for Rex & Zelda. (For eInk stuff, you'll want to strace awesome on FW 5.x, and cvm on older devices. I usually go with strace -fittv -e trace=ioctl -p $(pidof awesome)).
I don't rightly recall when the devcap stuff was added, but I would assume anything running FW 5.x should be fair game  . |
