: I figure that's one of the major reasons the CCH dev scene is nonexistent - the likelihood that anyone who is willing to pay well over $1,000 for one of these things depends on it working reliably and without issue to make a living. Not only would it be expensive to replace, but the downtime until replacement is a major setback to an artist's livelihood who needs it to work.
It's not a toy - it's a tool, and one that can do something that almost no other tablet computer can do nearly as well as it does.
However, while Wacom doesn't feel like handing out the source code that would reveal whatever kernel modifications they made to make the monitor mode switch work, I have a feeling that with enough effort, we could reverse-engineer their implementation. The Tegra 4 sources for other devices like the NVIDIA Shield Portable is already floating around out there, and that could be a potential launching point for an updated Android ROM, even if it might take a while before we get the monitor mode switch going. We might even have pen digitizer-related sources from Samsung's various Galaxy Note products that may also help to a limited extent, differences in digitizers aside.
There's more important things to tackle before any custom ROM efforts, however, like getting a custom recovery set up so that we can easily flash Nandroid backups and future custom ROMs.
As things currently stand, I haven't seen Wacom put out any ROM images and PC-based flashing utilities like most other Android manufacturers, so unless your idea of a recovery is hard-dumping the NAND with an eMMC reader and hard-flashing it with a known good dump if your system becomes unbootable, tread carefully.
