Touchscreen support

olli@ · Apr 6, 2021

I would like to buy a small monitor with touchscreen feature, e.g. this one or this one (non-affiliate Amazon links).
Since I haven’t used a touchscreen with FreeBSD before, I have a few questions …

Does FreeBSD support the touchscreen feature of monitors like the ones above? (Apparently it’s connected via USB and uses the uhid protocol. Windows doesn’t need a proprietary vendor driver, so I assume the touch function uses some standard protocol.)
I would like to use the touchscreen feature from within my own program (in C or Python). Is this possible?
Does it work in the text console (vt(4)), too, or does it require an X.org driver? Would be cool if I had both options, so I could write text-based (curses(3)) programs that react to touch gestures, as well as X.org-based programs (e.g. Python + Tkinter).

I do not need it as a mouse replacement, e.g. to control a browser with the touchscreen. Would be ok if that worked, too, but I don’t really need it.

It would be interesting to know. The touch function uses an usb connector, so if it behaves like a usb mouse / touchpad it could probably work in console too. No personal experience with these, sorry.

It's traditionally been spotty, but I haven't tried it in a while. It's likely you'd be better off buying an older model (ELO was once the standard) so there might have been someone who did the work to figure out how to make it work at some point in the past. These monitors tend to disappear as fast as they appear (One of your links is already dead a month later). I have 4 though monitors and only my ELO is still available.

Sorry for bringing this thread up again, but I still need an answer. I bought a random touchscreen from Amazon (this one), hoping to be lucky, but alas ... While the HDMI display works, the USB touchscreen feature is not recognized by FreeBSD 13 (I tried every driver I could think of, including webcamd). It works fine with Windows and Linux out of the box, though.

So the question remains. Does anymore know of a small touchscreen monitor that definitely works with FreeBSD? Preferably one that I could order in Germany without having to spend 100 € for shipping from abroad.

I have bought a dozen touchscreens. From AIO&Tablets to standalone, I2C and wmt.
Someday I hope to buckle down and figure them out.
wmt devices load the driver automatically. That seems to be my best attempt
So from there you must get it working with evdev and libinput.
I also had some luck with eGalax(4) touchscreens.

I know that it works on some laptop: the hp pavillon x2 should work with the wmt driver (combined with evdev driver)

Can we drill down on your needs. Looking at the link that is a Pi Screen. Those are going to take a whole lot more work than an amd64 based device. FDT overlays and the such on Arm.

So you are looking for 7" LCD touchscreen with USB input roughly? For what platform?

Unfortunately, typing “wmt” in the search box on Amazon doesn’t give useful results …

Phishfry · May 9, 2022

I am sorry. I failed to leave a reference to wmt(4). It is not a device per say.

How about hitting the bsd hardware lists and see what is in use?

Touchscreen devices

A database of all the hardware that works under bsd

bsd-hardware.info

Absent that I would consider contacting Vladimir. He is our touchscreen expert.

That screen can be used with a RasPi, but it’s not RasPi-specific. It can be connected via HDMI + USB to a regular PC (adm64), and the touch feature is recognized as a standard USB HID device by both Windows and Linux out of the box. But I was unable to make it work with FreeBSD, unfortunately. It is listed in the output of usbconfig (“ugen”), but I cannot use it.

I’m sorry, I should have been clearer.

Basically I’m looking for a smallish touchscreen for a regular amd64 PC:

Roughly in the range 7″ to 12″. Somewhat larger would be ok, too.
Resolution doesn’t matter much. 720p would be fine.
LCD or OLED or whatever, I don’t care, even a monochrome display would be acceptable.
I want to connect it to a regular amd64 PC running FreeBSD.
Preferably via HDMI or DisplayPort, but DVI or VGA would be ok (I’ve got converter dongles).
The touch feature should be connected via USB, because that’s what my PC has.
I would like to be able to recognize touch actions from within my own programs (Python or C). If I can do that via regular X11 events (as if it was a regular X11 pointer device or similar), that would be fine.

There is also hmt(4) which I use on one of my laptops.
No idea about the differences between wmt(4) and hmt(4).

Phishfry · May 9, 2022

With the eGalax driver it is based on a class of touchscreen controllers.
Nowhere on the touchscreen device packaging will you see 'eGalax'. It is the driver nickname and the same on Linux.
Several brand goods use this eGalax controller.
It is found in both laptops with touch screens and stand alone touch screen displays.

I really can't give a good recommendation. Usually I can point you to an ebay page.
I have 4+ AIO and 4+ tablets and some touch displays. So I need to get cracking.
This is on my bucket list. Kiosk with input. Not a glorified media player.

At least now we are identifying the drivers needed to try.

So are you using evdev under Xorg?

The difference seems to be USB.

I don't mean to dump on your thread but I finally have time to try out my 'All In One' Flat Panels with Touch Screen..

This message from /xf86-input-evdev really does not help much.
I guess you just plug in settings and retry until it works?

Code:

Xorg-server has been installed.

If your kernel is compiled with the EVDEV_SUPPORT option enabled
(default starting from FreeBSD 12.1) it is recommended to enable evdev mode in
pointer device drivers like ums(4) and psm(4). This will give improvements like
better tilt wheel support for mice and centralized gesture support via
xf86-input-synaptics or libinput drivers for touchpads.

This is also needed for PS/2 devices to be properly detected by Xorg when
moused service is disabled in /etc/rc.conf and kernel is compiled with
EVDEV_SUPPORT.

To enable evdev in such a device, run the following:

# sysctl kern.evdev.rcpt_mask=6

To make it persistent across reboots, add the following to /etc/sysctl.conf:

kern.evdev.rcpt_mask=6

In case you're using a serial mouse or any other mouse that *only* works over
sysmouse(4) and moused(8) on an evdev enabled kernel, please run this:

# sysctl kern.evdev.rcpt_mask=3

To make it persistent across reboots, add to this /etc/sysctl.conf:

kern.evdev.rcpt_mask=3

So I get movement onscreen of my pointer in Xfce4.
Nothing showing in Event 5 so touch must be Event 6.
Yup.

OK I finally patched together the last piece of the puzzle. Screen Taps.
I could drag the cursor around with my finger but no taps worked. Useless.

Now I tested on another touch AIO and got it working. I have touch and can use xfce4 menu.
/usr/local/etc/X11/xorg.conf.d/30-tap.conf

Code:

Section "InputClass"
Identifier "touchpad"
Driver "libinput"
  MatchIsTouchpad "on"
  Option "Tapping" "on"
  Option "NaturalScrolling" "on"
  Option "ClickMethod" "clickfinger"
EndSection

Touchscreen support
