What is the output of the following commands? $ grep -A 9 -B 2 -i touch /proc/bus/input/devices [To see if the touchpad is still recognized by the kernel] $ grep -iE '(synaptic|option)' /var/log/Xorg.?.log [To see what the X server does with the touchpad] And may be the contents of /etc/X11/xorg.conf, here especially the "InputClass" sections. -- Best regards, Jörg-Volker.
