calibration for Thinkpad X200t fails

[Rolf Leggewie]

I am starting the calibration process on a Thinkpad from unity-control-center and then move on to "Wacom Tablet". The tablet is recognized and works with the stylus. Then I start to calibrate the screen by choosing the "Calibrate" button and following the instructions on screen to click the cross-hairs. Invariably, when I hit the second cross-hair (the one on the upper right) the process aborts with "Mis-click detected, restarting" no matter how accurately I click.

FWIW, the process completes fine with xinput_calibrator. Here is the output.

$ xinput_calibrator
Warning: multiple calibratable devices found, calibrating last one (Serial Wacom Tablet eraser)
 use --device to select another one.
Calibrating standard Xorg driver "Serial Wacom Tablet eraser"
 current calibration values: min_x=0, max_x=26312 and min_y=0, max_y=16520
 If these values are estimated wrong, either supply it manually with the --precalib option, or run the 'get_precalib.sh' script to automatically get it (through HAL).
 --> Making the calibration permanent <--
  copy the snippet below into '/etc/X11/xorg.conf.d/99-calibration.conf' (/usr/share/X11/xorg.conf.d/ in some distro's)

Change '!!Name_Of_TouchScreen!!' to your device's name in the config above.

$ xsetwacom --list

My touchscreen is shown in the unity configuration applet as Tablet WACf004.
