Hi Vladamir,

I did some extra ferreting around and found cause of problem.

When I did update on installed 12.1 pkg I pull in new version of xorg which has
moved to udev based device discovery and defaults to using libinput for all
found devices (as per log I submitted)

To get KVM EvTouch I need to ensure I am using evdev driver as that is that
your utouch fix hooks into.

So to fix issue I just added overriding configuration to into:
/usr/local/etc/X11/xorg.conf.d

<<UTOUCH OVERRIDE>>
$ cat /usr/local/etc/X11/xorg.conf.d/99-qemu-input.conf 
#
# Overide libinput
#
Section "InputClass"
        Identifier "evdev touchscreen catchall"
        MatchIsTouchscreen "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection
<<END UTOUCH OVERRIDE>>

So now have FreeBSD Desktop back and up running and with much much simpler
overall configuration.

Cheers,


John Hartley
