This is a forked version of xcalibrate, which is an alternative to xinput_calibrator (as seen on github, FreeDesktop, Ubuntu, etc.).
Original version

Similarities:

• For Unix-like OS
• Calibrates touchscreens

Differences:

xinput_calibrator features precalibration, timeouts, misclick detection, fake driver testing, and a resizable window. xcalibrate features none of those things, but offers some other features not present in xinput_calibrator, including pre-save cal test, cal quality indicator, arbitrary cal point count, and a slightly more informative GUI. Also, the source is quite simpler.

While reinderien's calibration tool is excellent, however, this script wouldn't work on my personal CF-19 laptop, since the touchscreen shows up as a keyboard device. This fork has been modified to show BOTH keyboard and pointer devices in the selection now. It is also modified to actually save the .conf file in the correct directory automatically (instead of having to mess around running text editors in root and saving changes manually). This does however mean the script needs to be run as sudo.

First you need the dependencies sudo apt install python3-tk python3-numpy

You can then run: sudo python3 xcalibrate.py To calibrate the display

Optionally copy the xcalibrate.py file to /usr/bin/ Then copy the .launcher file to /usr/share/applications/
