When using Linux based Live CD to test Touchscreen on any machine so equipped.
Linux Speak:
#note the asterisk...capitalization is crucial.
Here's a sample. All this does is verify that the OS is "seeing" the Touchscreen equipment. It will look like this whether or NOT the touchpanel is working. IOW it checks connections on the motherboard and sees if the TSPCB in the lid is working.
In the case of a bad touch panel, the panel is sending input to the mobo.....just not the right input, as in the case of a bad circuit on the panel.
Early models use the PS/2 mouse driver and it would show up here in place of Fujitsu.
