I have installed touchegg and i can set gestures like tap with 2 fingers for emulate right click or pich zoom unzoom but i don't think this is real multitouch function
apt install touchegg
and add these to file /usr/share/touchegg/touchegg.conf
<gesture type="TAP" fingers="2" direction="">
<action type="MOUSE_CLICK">BUTTON=2</action>
</gesture>
<gesture type="TAP" fingers="3" direction="">
<action type="MOUSE_CLICK">BUTTON=3</action>
</gesture>
<gesture type="PINCH" fingers="2" direction="IN">
<action type="SEND_KEYS">
<repeat>true</repeat>
<modifiers>Control_L</modifiers>
<keys>KP_Subtract</keys>
<decreaseKeys>KP_Add</decreaseKeys>
</action>
</gesture>
<gesture type="PINCH" fingers="2" direction="OUT">
<action type="SEND_KEYS">
<repeat>true</repeat>
<modifiers>Control_L</modifiers>

I have tried a lot of live linux distros to verify if touch screen works.
In debian 11 has the same behavior as debian 12 so it is not software regresion.
All distros i have tried with xfce have same behavior with debian except fedora
that inside firefox you can pinch in - out for zoom unzoom and copy text with extended taping inside xfce double click on desktop also not work also on fefora.
In fedora with gnome3 seems to have better support for touch that fedora xfce.
Here says multitouch handled by toolkit or composer

Multitouch gestures can be handled in debian 12 xfce by touchegg very good
but the problem are not the gestures us the double click and tapping for extended time to emulate right click.

I noticed for the
Waveshare 22930 touchscreen
, the following is listed in dmesg:
So `input` is recognized for both touch and mouse, but only the mouse is registered as hid-generic at first. Touchscreen seems to be registered later. Maybe this is normal; unsure. Really surprised this is still an issue after all this time.
