Comment 8 for bug 549447

Yes, without doubt, we need an application WITH GUI (like the eGalax solution) to calibrate all touchscreens covered by evdev driver.
I see a lot of people that made a little app for doing this, but none of them are in the ubuntu repositories.

Check this blueprints:
https://blueprints.launchpad.net/ubuntu/+spec/mobile-general-resolution-for-touchscreen-handling
and the detailed version here:
https://wiki.ubuntu.com/JauntyTouchscreenHandling

In this last link you can notice a gui app to setup a touchscreen, not only calibration tool, also precision, swap axes, timeouts.. why this app isn't in actual ubuntu releases (and repositories)?
