I'm sorry, I missed the tag, and was referring to the content of your title and message text. I'll vote to reopen your question, as well as research your Touch Screen issue. – L. D. James Apr 28 '18 at 13:13

This is touch screen details of your exact Laptop model: Identify the entries of xinput. This is a question with answer for generic touch screen drivers: How to Determine which is your TouchScreen Driver. Which drivers have you installed? – L. D. James Apr 28 '18 at 13:26

There are two options as for now, both of them presented in following link: https://bugzilla.kernel.org/show_bug.cgi?id=198715#c14
The first option is to patch kernel manually and install it on your system, I've tested it, it works for my HP Envy x360 15-bq121dx.
Another option is to patch acpi table, people in discussion in link above report successful result. I haven't tried this method yet.

Download GNOME Tweaks from Ubuntu Software. Go to the Keyboard & Mouse section. Then go to Mouse, click Emulation, and select Area.
