[SOLVED] Issues with touchscreen in panasonic toughbook cf-31
Hello, I have a panasonic toughbook cf-31 and I am trying to get the to get the touchscreen working. After messing around with configs and stuff (and following a million tutorials) I finally got the touchscreen to pick up (it shows up as a fujitsu usb touchscreen) but my problem is that, no matter what I do I cannot get the touchscreen calibrated. I don't know what to do next. And before someone says that this issue is duplicated, I did try the solutions to similar posts and they didn't work.

Re: [SOLVED] Issues with touchscreen in panasonic toughbook cf-31
Wayland or X11? And which Desktop Environment (DE) are you using?
can you please share exactly how and what solutions you have already tried? (this will save us from suggesting things you've already ruled out)

Re: [SOLVED] Issues with touchscreen in panasonic toughbook cf-31
Hi, sorry for not giving all details from the beginning I'm running KDE (latest stable) in X11. I tried wayland too but wayland doesn't want to pick up the touchscreen. I had to mess around with xinput (or something I don't remember clearly), to get the touchscreen picked up by X11 but lspci doesn't detect it as being present. neither does lsusb but when I touch it the cursor does move (not where I want it to but it does move nonetheless).

Re: [SOLVED] Issues with touchscreen in panasonic toughbook cf-31

Re: [SOLVED] Issues with touchscreen in panasonic toughbook cf-31
Sorry for the late reply, my laptop had unrelated overheating issues that I had to fix so it doesn't cook itself and it took some time to get sorted.
Here is the output of xinput list
WARNING: running xinput against an Xwayland server. See the xinput man page for details.
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]

⎣ Virtual core keyboard id=3 [master keyboard (2)]

Re: [SOLVED] Issues with touchscreen in panasonic toughbook cf-31
Since you're on Wayland now,
libinput list-devicesdoes the touchscreen show up there?
If it shows, I heard there is "Caliberation" option on KDE system settings, and you'd need to follow on screen instructions...
also When it did work in X11 (cursor moved but uncalibrated), what exactly did you do to make it show up? Did you add a file to /etc/X11/xorg.conf.d/?, use xinput set-prop commands? load a specific kernel module?

Re: [SOLVED] Issues with touchscreen in panasonic toughbook cf-31
Hi, thank you for the quick reply.
I don't really know if the touchscreen shows up in there, since I heard that linux sometimes confuses the trackpad with the touchscreen. This only happens when the laptop is freshly setup, I had to mess around with some config files to get it to work. I had to edit
/etc/default/grub to include this
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.nomux i8024.noloop so the trackpad got recognized and working.

Re: [SOLVED] Issues with touchscreen in panasonic toughbook cf-31
The good thing is it's detected, the bad thing is its identified as a pointer
what if you create a udev rule smtg as
SUBSYSTEM=="input", ENV{ID_VENDOR_ID}=="0430", ENV{ID_MODEL_ID}=="0501", ENV{ID_INPUT_TOUCHSCREEN}="1", ENV{ID_INPUT_POINTER}="0"also it should be `i8042.nomux i8042.noloop` instead of "i8024"...

Re: [SOLVED] Issues with touchscreen in panasonic toughbook cf-31
Hi, how do I create said udev rule. Also thanks for the correction, I had written it correctly on the actual file in the laptop and wrote it wrong here (yes I manually wrote that instead of copy and pasting).

Re: [SOLVED] Issues with touchscreen in panasonic toughbook cf-31

sudo nano /etc/udev/rules.d/99-meow.rulesthen paste
SUBSYSTEM=="input", ENV{ID_VENDOR_ID}=="0430", ENV{ID_MODEL_ID}=="0501", ENV{ID_INPUT_TOUCHSCREEN}="1", ENV{ID_INPUT_POINTER}="0"and force the system to reload the config

Re: [SOLVED] Issues with touchscreen in panasonic toughbook cf-31
Run `libinput list-devices`, see if its detected as other than pointer, and test the screen (also remember about caliberation option in KDE settings?)

Re: [SOLVED] Issues with touchscreen in panasonic toughbook cf-31
\o/
Device: Fujitsu Component USB Touch Panel ... Capabilities: pointer touch
Now, try the calibration option in KDE system settings, follow the onscreen instructions, and see how the screen behaves now!

Re: [SOLVED] Issues with touchscreen in panasonic toughbook cf-31
Kde settings say that there is no touchscreen connected. I tried looking for drawing tablet too but it says the same thing, no drawing tablet is connected.
That's weird, because when I touch the screen the mouse pointer moves, not were I want it to, but it definitively moves.

Re: [SOLVED] Issues with touchscreen in panasonic toughbook cf-31
I see, run `libinput debug-events` and touch/try to move the cursor, do you see "POINTER_MOTION" or "TOUCH_DOWN/TOUCH_UP"?

Re: [SOLVED] Issues with touchscreen in panasonic toughbook cf-31
When I ran libinput debug-events, I see lines like
event4 POINTER_BUTTON +39.552s BTN_LEFT (272) pressed, seat count: 1
event4 POINTER_BUTTON +40.232s BTN_LEFT (272) released, seat count: 0 when touching the touchscreen. I don't see any new line when I touch and move my finger across the touchscreen.

Re: [SOLVED] Issues with touchscreen in panasonic toughbook cf-31
can you install https://archlinux.org/packages/extra/x86_64/evtest/
and run
sudo evtest /dev/input/event4touch and move your finger across the touchscreen and look for
*ABS_X and ABS_Y events (absolute positioning - good)
*REL_X and REL_Y events (relative movement - wrong for touchscreen)
*or just button events (even worse)
?

Re: [SOLVED] Issues with touchscreen in panasonic toughbook cf-31
The output of evtest /dev/input/event4 is something like
Event: time 1779545121.476597, -------------- SYN_REPORT ------------
Event: time 1779545121.484691, type 3 (EV_ABS), code 0 (ABS_X), value 9208
Event: time 1779545121.484691, type 3 (EV_ABS), code 1 (ABS_Y), value 11719So based on what you said before is good, I think.
So what should I try next?

Re: [SOLVED] Issues with touchscreen in panasonic toughbook cf-31
Please run `sudo evtest /dev/input/event4` again, but this time capture a complete single interaction:
*place one finger on the screen (and keep it down) -> move it slowly to another location -> lift the finger -> then copy the entire block of events from touch-down to touch-up...
also, while running evtest, gently touch the four extreme corners of the screen (top‑left, top‑right, bottom‑right, bottom‑left) and post the whole block too (you can use pastebin to post those large blocks...)
btw, what's you screen resolution? `kscreen-doctor -o`

Re: [SOLVED] Issues with touchscreen in panasonic toughbook cf-31
create a file /etc/libinput/local-overrides.quirks
and add
[Fujitsu Component USB Touch Panel]
MatchName=Fujitsu Component USB Touch Panel
ModelTouchscreenNoFingerEvent=1reboot
and now if you run `libinput debug-events` do you see "TOUCH_DOWN/TOUCH_MOTION..." instead of "POINTER_BUTTON"?
Lets see that, till then I'll test my knowledge of matrices

Re: [SOLVED] Issues with touchscreen in panasonic toughbook cf-31
when running libinput debug-events after making that file and rebooting, there is a message in red saying
Unknown key ModelTouchscreenNoFingerEvent in [Fujitsu Component USB Touch Panel] (local-overrides.quirks)
Failed to load the device quirks from /usr/share/libinput and /etc/libinput/local-overrides.quirks. This will negatively affect device behavior. See https://wayland.freedesktop.org/libinput/doc/1.31.2/device-quirks.html for details.I also checked kde settings app and now the screen is showing under touchscreen but every setting is grayed out, and there aren't many settings for the touchscreen. I would send you a screenshot but I have a problem where in some applications the text is garbled and in other applications, video is garbled, but only for that application, specially when playing a cinematic in a game. This doesn't happen in firefox tho, I don't know why

LoL 404, anyways mine was running on Debian, which seems deprecated in the newer versions... 
so in your case, just remove that file as it's just redundant
also, I managed to calculate it, lets see if its correct or not
SUBSYSTEM=="input", ENV{ID_VENDOR_ID}=="0430", ENV{ID_MODEL_ID}=="0501", ENV{LIBINPUT_CALIBRATION_MATRIX}="0 1.1256 -0.0600 -1.0886 0 1.0564"Offline
