Rather a lot doesn't work on this Lenovo as it's old and tired.
But enough to make it a useful machine. As you can see, I use
a wireless mouse if ever I need to touch it. (Normally it
runs minidlna "headless".)
For these listings, I commented out my setup routine, which
would have disabled the touchscreen.
The gestures should be listed in the User Guide, usually
available on the internet: just search for manual modelname.
Ask if you want me to send a U[34]30{,p} Touch manual.
Cheers,
David.
