Bug Description
When I try to calibrate the touchscreen on my laptop (HP EliteBook 2760p, Wacom Serial Tablet WACf004) the result gets worse and worse with every calibration. The area on which the touchscreen is effective becomes smaller every time to the point where it is completely unusable.
This can be verified with "xsetwacom --get 15 area", right now this gives me "-9978 -6651 6336 -4878".
I can reset this by manually setting a new area, e.g. "xsetwacom --set 15 area 0 0 25000 16000"
However, xsetwacom only works for the current session, after a reboot all information is lost and the calibration is off again.
What should happen: the area for the touchscreen is improved with calibrating
What happens instead: the area gets smaller for every calibration
I'd be happy to contribute a bit in fixing this bug, but my knowledge is limited.
Meanwhile, I'd appreciate a workaround: how can I reset the area used for the touchscreen to the default?

Note that "xinput_calibrator" is a bit more verbose and warns me:
Warning: multiple calibratable devices found, calibrating last one (Serial Wacom Tablet touch)
use --device to select another one.
Calibrating standard Xorg driver "Serial Wacom Tablet touch"
current calibration values: min_x=0, max_x=2640 and min_y=0, max_y=1630
With the default settings, it gives me a very wrong result resulting in a similar area as reported.
By using "xinput_calibrator --device 15" I get proper values: "-1232 -523 26217 16525".
My best guess is that the Wacom calibration through the control centre is using the wrong input device.
