Virtual frambuffer switching for Kobo

[frostschutz]

the Kobo sees an msdos partition and so nickel/hindenburg doesn't complain continually about the sd card being unreadable and needing to be formatted.

I have them as ext*.

But your solution with partitions looks good.

As a note for you:

Busybox itself allows choosing which programs run with suid permissions and which ones don't when it's owned by root. (By default busybox exits suid root before running it's internal applets unless instructed not to -- even if the suid bit is set on busybox as far as I know -- but I'm no expert...).

Yup that's what I was missing. It wouldn't work any other way either, even if you made a real copy (and wasted 1MB storage for it) and renamed it or symlinked only the suid applets to it - you couldn't stop anyone making more symlinks for the remaining applets.

I didn't know busybox had this ability to handle suid properly.

You obviously know what you are doing - hack on.

Courtesy update...

This implements the double write flipped and unflipped fix, so that the buffer is restored correctly on both the KoboGlo and KoboAuraHD automatically without needing to know which device it's running on. It hasn't been tested on KoboGloHD.

May be released as part of GPL 2 or 3 code in the future.

Includes an example script to put hindenburg and nickel to sleep, and wake up a processes called vt52u (not included), or vice versa when saving or restoring the framebuffer.

enjoy.
