[OK] Need help with touchscreen calibration

[Gigab]

Hello everyone,
I recently installed Linux Mint Uma on my computer, with Kernel 5.11 (thank you @SMG) so that my two Elo touch screens would be recognized (kernel 5.4 only recognized one screen)

The screens light up well, but are not calibrated at all, the mouse moves more or less 10cm to the left or right of my finger.
I tried xinput calibrator, but it handles like there is only one big screen.

So, I made in the Terminal
- "xinput" to get the device ID
- "xrandr" to get the list of screens
- "xinput map-to-output"

The result is that the calibration is done really well, but the problem is that this setting is lost each time the PC is restarted.
Do you have a solution to make this setting permanent and that at each start, the screen is correctly calibrated?

Thank you very much in advance !!

I answer myself. I found how to calibrate the screens at startup.
I created a txt file with the map to output command and put the file in the programs at startup.
