It seems to be not related only to M3800 laptop but others like HP Spectre too.
Regarding this topic I'm able to have a working touchscreen when I removed

Hello,
Tried a fresh install of Ubuntu 20.04.2 and problem is the same even I haven't
activated fractional scaling.
The touchscreen is working good on live iso.
It's also working good on GDM before a session is opened.
Hope you can fix this bug.
Best regards.

Oh actually don't delete any config files. I just noticed we ship some
default ones like:
/usr/share/X11/xorg.conf.d/40-libinput.conf

Just a little precision.
If I open my "rom1" session where I have enabled and disabled the
fractional scaling, then I close it and open the "test" session my
touchscreen is not working.
If I reboot the computer and open "test" session only my touchscreen is
working.
It seems that open my "rom1"
I never created myself any xorg config file.
I will try to delete it. Do you have the file location please ?

I assume the device in question is the 'SYNAPTICS Synaptics Large Touch
Screen'. The log file in comment #56 shows that xserver-xorg-input-
libinput is aware of the device but not using it.
It also looks like you have a Xorg config file that is trying to
configure that device so that config file
11 matches
