Experimente este :
If your touchscreen has an USB interface, and it isn't working, then you may need to blacklist the usbtouchscreen driver for it to work:
sudo modprobe -r usbtouchscreen
If your touchscreen begins to produce events, then you can permanently blacklist the usbtouchscreen driver:
echo "blacklist usbtouchscreen" | sudo tee -a /etc/modprobe.d/blacklist.conf
Espero que isso ajude.
