Use xorg.conf to fix touchscreen X axis reversed

I setup Fedora 35 with my Titan6001 touchscreen. Although Linux is responding to touches, the X axis is reversed (touch on the right mouse goes to left side, and vice versa). Y axis is fine. How do I reverse this? I'm using X11 (not Wayland) I created a new xorg.conf using "Xorg -configure" command but it did not contain a section for the Titan6001 (eGalax) device. But I found one on an old post and added it to my xorg.conf as follows: Section "InputDevice" Identifier "EETI" Driver "egalax" Option "Device" "usbauto" Option "Parameters" "/var/lib/eeti.param" Option "ScreenNo" "0" Option "InvertX" "true" EndSection But it made no difference (the InvertX had no effect). I wonder if this section is even being accepted. My Xorg.0.log shows: 72.646] (II) config/udev: Adding input device eGalax Inc. USB TouchController (/dev/input/event4) [ 72.646] (**) eGalax Inc. USB TouchController: Applying InputClass "evdev touchscreen catchall" [ 72.646] (**) eGalax Inc.

USB TouchController: device removed [ 72.674] (**) Option "config_info" "udev:/sys/devices/pci0000:00/0000:00:1a.0/usb3/3-2/3-2:1.0/input/input13/event4" [ 72.674] (II) XINPUT: Adding extended input device "eGalax Inc.

USB TouchController: (accel) selected scheme none/0 [ 72.674] (**) eGalax Inc. USB TouchController: (accel) acceleration factor: 2.000 [ 72.674] (**) eGalax Inc. USB TouchController: (accel) acceleration threshold: 4 [ 72.676] (II) event4 - eGalax Inc. USB TouchController: is tagged by udev as: Touchscreen [ 72.676] (II) event4 - eGalax Inc. USB TouchController: device is a touch device [ 72.678] (II) config/udev: Adding input device eGalax Inc. USB TouchController (/dev/input/mouse1) I notice it references mouse1, is that a clue? Should I create a section for that? So next I tried xinput --set-prop "eGalax Inc. USB TouchController" "Evdev Axis Inversion" 1, 0 But the property was not recognized. So I tried to list available properties and see: Device 'eGalax Inc. USB TouchController': Device Enabled (142): 1 Coordinate Transformation Matrix (144): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000 libinput Calibration Matrix (278): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000 libinput Calibration Matrix Default (279): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000 libinput Send Events Modes Available (261): 1, 0 libinput Send Events Mode Enabled (262): 0, 0 libinput Send Events Mode Enabled Default (263): 0, 0 Device Node (264): "/dev/input/event4" Device Product ID (265): 3823, 1 Can the coordinate transformation matric or input calibration matrix achieve what I want? (Assuming I must set this from the command line, and not xorg.conf)
