Taking apart
Two small screws on connector side - probably just remove and the housing should be hooked or somesuch

Hacking
ProTab2 XXL runs Doozan's Debian (deprecated). You need the script.bin from stock firmware.

To make ft5x touchscreen work with X out of the box you need to disable CONFIG_FT5X0X_MULTITOUCH in drivers/input/touchscreen/ft5x_ts.h and recompile ft5x_ts module as described at Rhombus Tech.

miniand's lubuntu starts but hangs after login. Something is wrong with either X or the display manager ...

FT5X touchscreen issues
The screen dimensions and axes will be confused. You will need to change your script.bin as described at eLinux.org like following: ctp_screen_max_x = 600 ctp_screen_max_y = 1024 Axes can then be corrected with the Debian package xinput by running: xinput set-int-props "ft5x_ts" "Evdev Axis Calibration" 32 0 1024 0 600 You could also try xinput-calibrator which sources (since you have to compile it ARM*) can be either found at Ubuntu/Launchpad repositories or on https://github.com/tias/xinput_calibrator.
