Surface pro 4 iptsd.service does not exist

Hi Guys,
Although I experience no problem on my MS Surface Pro 4 ... type keyboard and touchscreen function as normal. But I have a question about enabling iptsd.

The command to enable iptsd.service for surface-linux reports:
"Failed to enable unit: Unit file iptsd.service does not exist:

Is this a problem or could I ignore this?

Do you have installed iptsd?
