Build
Before using, we need to get the code and build it:
$ bzr branch lp:~utouch-team/utouch/mtview
This code is an import of a git master branch. If, for any reason, branching doesn't work, you can grab the original here:
$ git clone http://bitmath.org/git/mtview
Once you have the code, you can build:
$ cd mtview $ make
Testing the Device
In order to run mtview, you will need to know the input node for your multitouch device. To find this out, use the instructions here:
Let's say that after running lsinput, you discovered that your MT device input node was /dev/input/event10, then you would run mtview with the following command:
sudo ./bin/mtview /dev/input/event10
At this point, a window will come up and mtview will capture all touch events. Some examples of mtview in action can be found here:
Some known issues with mtview to keep in mind:
- sometimes the screen starts up with a black background, sometimes with a white one
- the first touch is not captured
- around the edges of the screen, touch points are offset; this is a bug, and not (necessarily) a problem with your hardware
