Android on X220t/X201t

Keyboard, mouse support, external storage support (fat32 didnt try exFat)

I might try checking out the code and having a go at it (not much of a dev just fairly technical) seeing if I can incorporate the touchscreen support into the kernel.

Which one did you test? I see 4 different builds. Would love to give it a go.

The only Android that works on my X220 is the ASUS build. The WiFi (Intel 6205), Bluetooth, and touchscreen do not work. The rest seems to work for the most part. Can't do much without WiFi. :-(

Yea the ASUS build is the one I used. I did some reading, I'm trying at building a generic build with ICS. The touch screen issue is the main thing for me. If I can get at least that working it would be an epic tablet. Rotational buttons would be a whole other issue. Since I don't think the X201T has an accelerometer, there is no way to simply autorotate (I could be wrong but haven't seen anything for an accelo).

If anyone has any ideas on how to incorporate the wacom touch stuff please let me know I would love to get a build out there for alot of the PCs that use it.

Strange that you mention wifi not working. It worked just fine for me. No issues at all. In fact seemed to work better on android than with Windows.

The x201t has an accelerometer (I think all ThinkPads has one?).

The main feature of the accelerometer for ThinkPads is to detect high increase of acceleration (when you drop it) and then park the arm for the harddrive (to protect it). Since you can drop it from all positions so must there be an three dimensional accelerometer. In the x200t/x201t/x220t they also added an "auto rotation" feature.

You can also use it for other applications if you are handy. Here is someone who edited Neverball and Tux Racer so they will use the accelerometer as an input device. Works on my x201t.

Nice then ICS should be able to take advantage of it. Loading it up on it seemed pretty pain free using the ASUS build. I was creating a generic one that seemed to have the wacom support built into the kernel. But I think I need to setup other drivers. Also the lenovo accelerometer support? Also looking at a way to build support for all the other lenovo parts like the accelerometer which I know doesn't work at this time.

Im still working on a functioning build for this. It works just fine with mouse/keyboard support. Seems like apps just work. So a decent amount of work to get this functioning with this machine. Im excited. It would be the heaviest tablet I own. But also a fairly powerful one too Quad Core action and 8Gb of ram. I might look at swapping out the SATA storage for an SATA SSD.

here's another thread about ubuntu on x220t. I think it has a lot of useful information about drivers

Which Wifi card do you have? I have the Intel 6205. I'm working with an X220T btw. I'm surprised that there's not a greater initiative to have supporting builds for these Thinkpads.

I think its just that not enough people know about android-x86 is all. Distrowatch and some others don't appear to consider android a "linux" distro. But seems to be very linux to me. Kernel and all is there. I found some drivers googling around (should have saved the page to link it) that had the wacom-drivers without the xorg stuff. otherwise they dont work correctly. They are just basic drivers which is what we need to get this to work on android.

I got a bit of a learning curve here as I am pretty new at this. But the laptop isnt doing anything so I figure I can just keep reinstalling and tinkering till I get it right.

I guess I have a question here. Been looking around but no solid answers. Could I compile the wacom drivers into android? Since the linux kernel is the linux kernel I imagine it should work. However what I dont know is how to compile the drivers in android. Linux easy stuff. I had some challenges doing it in android. Missing various build tools needed to make it happen. Anyone got any info?

Anyone who might want touchscreen and wifi support for android x86 on the x220 should visit the link below and vote for it as a fix on the URL below. I didn't submit it, I just stumbled upon when looking for solutions.
