Hey guys,
I hope you can help me with my problem. Hardware is Raspberry Pi3B+ with a 5" joy-it touchscreen.
My touchscreen is driving me crazy. I bring the touchscreen function to life adding this to the config.txt:
After this I create the calibration file: „/usr/share/X11/xorg.conf.d/99-calibration.conf"
And add the calibration data:
I also add fbcon=map:10 to the cmdline.txt
The touch function works inaccurate and I can't use 1cm of the display in every direction which makes the display useless.
Change the calibration according to xinput calibrator or changing the x,y data is doing nothing it's always the same.
I don't know what to do anymore. With the joy-it manufacturer version of Raspbian Jessie everything works fine.
I hope you can help me.
