i have been banging my head i tried usign xinput calibrator in the linux vm and then copying it to /etc/gesture/99-touchscreen.conf as follows but nothing

/etc/gesture/99-touchscreen.conf :
Section "InputClass"
        Identifier      "Silead TS calibration"
        MatchDevicePath "/dev/input/event*"
        MatchProduct "silead_ts"
        Option  "MinX"  "2349"
        Option  "MaxX"  "68886"
        Option  "MinY"  "282"
        Option  "MaxY"  "65407"
        Option  "SwapXY"        "0" # unless it was already set to 1
        Option  "InvertX"       "0"  # unless it was already set
        Option  "InvertY"       "0"  # unless it was already set
EndSection

also tried in the kernel with no result

input-core.custom=1 input-core.invert_x=1

of_touchscreen.custom=1 of_touchscreen.min_x=1

also dmesg:
