    Hi There,

    I am currently trying to get a older Touchscreen, the LG Flatron L1510SF (15″ @ 1024×768) with touch-output via USB, to work with a Raspberrypi 3 and Max2play using Jivelite and the joggler skin.

    I found this tutorial (in Dutch) on the internet, specific for the same screen, but I run into trouble.

    I installed xinput_calibrator and this works fine. However to save the calibration data you have edit or create the following file:

    /etc/X11/xorg.conf.d/99-calibration.conf

    However after adding this file with the parameters and rebooting, the LXDE gui will not start and I’m stuck in terminal mode. LXDE is back again when I delete the file and reboot.

    Any Ideas how to fix this?

    Best regards,

    Megantonneke

    I tried again using the exact same /etc/X11/xorg.conf.d/99-calibration.conf entries as explained in the previous mentioned tutorial, as it deals with the extact same monitor. This works! I still don’t know why it got botched by the actual calibration numbers that xinput_calibrator recordered, but I am gonna leave it with that.

    So /etc/X11/xorg.conf.d/99-calibration.confnow states:

    Section "InputClass"
    	Identifier	"calibration"
    	MatchProduct	"ITM Inc USB Touch Panel"
    	Option	"Calibration"	"125 4015 3940 160"
    	Option	"SwapAxes"	"1"
    	Option "InvertX" "true"
    	Option "InvertY" "true"

    Greetings,

    Megantonneke

    Hello Megantonneke,
