I want to calibrate a touchscreen named "eGalax Inc. USB TouchController" on my Raspberry Pi. I think X and Y axes of the touchscreen are inverted. I used xinput_calibrator for this purpose. When I followed the xinput_calibrator instructions, it printed the following output:

Calibrating standard Xorg driver "eGalax Inc. USB TouchController"
    current calibration values: min_x=0, max_x=65535 and min_y=0, max_y=65535
    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)
Section "InputClass"
    Identifier  "calibration"
    MatchProduct    "eGalax Inc. USB TouchController"
    Option  "MinX"  "20697"
    Option  "MaxX"  "20595"
    Option  "MinY"  "53036"
    Option  "MaxY"  "53090"
    Option  "SwapXY"    "1" # unless it was already set to 1
    Option  "InvertX"   "0"  # unless it was already set
    Option  "InvertY"   "0"  # unless it was already set
EndSection

And it made no changes in the touchscreen behavior (It is not calibrated yet).

After that, I created the '/etc/X11/xorg.conf.d' directory and copied the snippet above (Section ... EndSection) into the '99-calibration.conf' in that directory as stated above, and finally rebooted the Raspberry Pi. But it didn't make any changes. What's going wrong?
