[SOLVED]Touchscreen not recognized

I have an Asus P16 H7600 with a touchscreen, which I'd like to get enabled. According to the Arch wiki touchscreen article,

If you ever tried to set up a touchscreen device in Linux, you might have noticed that it is either working out of the box (besides some calibration), or is very tedious, especially when it is not supported by the kernel.

Unfortunately I seem to be in the latter situation, since xinput shows no reference to the touchscreen:

# xinput
⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ ASUE1900:00 04F3:31AF Mouse             	id=10	[slave  pointer  (2)]
⎜   ↳ ASUE1900:00 04F3:31AF Touchpad          	id=11	[slave  pointer  (2)]
⎣ Virtual core keyboard                   	id=3	[master keyboard (2)]
    ↳ Virtual core XTEST keyboard             	id=5	[slave  keyboard (3)]
    ↳ Power Button                            	id=6	[slave  keyboard (3)]
    ↳ Video Bus                               	id=7	[slave  keyboard (3)]
    ↳ Video Bus                               	id=8	[slave  keyboard (3)]
    ↳ Power Button                            	id=9	[slave  keyboard (3)]
    ↳ ASUE1900:00 04F3:31AF Stylus            	id=12	[slave  keyboard (3)n
    ↳ Asus WMI hotkeys                        	id=13	[slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard            	id=14	[slave  keyboard (3)]

These HID kernel modules are loaded:

# lsmod | grep hid
uhid                   20480  1
hid_multitouch         36864  0
hid_generic            12288  0
i2c_hid_acpi           12288  0
i2c_hid                40960  1 i2c_hid_acpi
mac_hid                12288  0

At this point I'm not sure what needs to happen to get the touchscreen to show up. Any suggestions?

Re: [SOLVED]Touchscreen not recognized

Sure "ASUE1900:00 04F3:31AF Stylus" isn't the touchscreen?
How do we assert that it doesn't work?
If you run 

sudo libinput debug-events

and then sully your screen with fingerprints, does that generate any events?

If not, please post a general oversight of the HW

I'm not positive, but I'm pretty sure that's the driver that would respond to an Asus stylus rather than a finger.

If you run 

sudo libinput debug-events

and then sully your screen with fingerprints, does that generate any events?

No, nothing generated from touching the screen:

Re: [SOLVED]Touchscreen not recognized

Stylus looks like part of the touchpad hmm
It's certainly not attached via usb or pci
Please post your complete system journal for the boot: 

sudo journalctl -b | curl -F 'file=@-' 0x0.st

Asus P16 H7600

According to google™ it looks like the touchscreen model is H7606?
Can you toggle the touchscreen in the UEFI/BIOS settings?
https://www.asus.com/laptops/for-creato … gen-intel/ doesn't seem to advertise any touchscreen?

Re: [SOLVED]Touchscreen not recognized

Doh! Now I feel like an idiot. You are correct. I have last year's version of the Asus P16, model H7600. The specs I was reading were for the current model, H7606. It turns out that the 7606 has a touchscreen, but the older 7600 does not.

Oh well. No big loss. I'm actually not a big fan of touchscreens, but thinking it was available I thought I might give it a try for a little while.

Thanks for helping get this straightened out.
