TUTORIAL: Calibrate touch screen on latest Raspbian

[GAMELASTER]

Since circa March update of Raspbian, there is used evdev instead of libinput, which causes that default xinput calibrator doesn't work anymore.
That's reason that why I created evdev-calibration application. I must note that it's not absolutely accurate, but still better than nothing.

Installation

Code: Select all

sudo apt-get install libsdl2-dev libsdl2-ttf-dev
cd /tmp
wget https://github.com/gamelaster/evdev-calibration/releases/download/0.2/evdev-calibration-armv7.tar.gz
tar xvf evdev-calibration-armv7.tar.gz
export DISPLAY=:0
./evdev-calibration

And then just follow the instructions.

Known issues
- There is no support for rotated displays

If you have any questions, ask it!

(btw. I hope I selected a right category, if not, please move it!)

I used
sudo apt-get install xinput-calibrator
Then Menu / Preferences / Calibrate Touchscreen

I have installed xinput for my RPi and ran the calibrator program under preferences but can seem to find instructions on how to change the touch pointer from landscape to portrait mode. I slide my finger up the screen and the curser moves left.
Is there some that can help? Thanks!

I know this is an old post. I'm familiar with xinput calibrator but the portrait orientation of the touch surface seems to still be an issue. Did you find a solution?

Use display_rotate in order to turn the video.

Follow this guide to rotate the digitizer: http://www.circuitbasics.com/raspberry- ... -rotation/

I recently setup a portrait oriented kiosk that had to tackle rotating both the screen and the digitizer.
