I ran xinput_calibrate with the calibration change you suggested (Option “Calibration” “3936 227 3880 268”).

I was finally able to click the mark in the bottom right corner. Here is the result:

Section “InputClass”
Identifier “calibration”
MatchProduct “ADS7846 Touchscreen”
Option “MinX” “11753”
Option “MaxX” “11116”
Option “MinY” “23023”
Option “MaxY” “28074”
Option “SwapXY” “1” # unless it was already set to 1
Option “InvertX” “0” # unless it was already set
Option “InvertY” “0” # unless it was already set
EndSection

209

For now don’t run xinput_calibrate. Just change the values in etc/X11/xorg.conf.d/99-calibration.conf.

Also execute

sudo cp /usr/share/X11/xorg.conf.d/10-evdev.conf /usr/share/X11/xorg.conf.d/45-evdev.conf

Then reboot Volumio.

210

Now the cursor seems to jump all over and changes from a mouse pointer to a hand pointer and a typing cursor.

Here are my files:

Try reverting the changes I suggested for 99-calibration.conf and renaming /usr/share/X11/xorg.conf.d/40-libinput.conf to /usr/share/X11/xorg.conf.d/40-libinput.conf.bak. Then reboot.

212

OK, I tried again with a fresh install of volumio. Here is everything I did and my config files.

The mouse cursor stays in the upper right quadrant of the display no matter where I place the stylus.

Also I received a very much unappreciated message when trying to post this yesterday.
“We appreciate your enthusiasm, keep it up! That said, for the safety of our community, you’ve reached the maximum number of replies a new user can create on their first day. Please wait 13 hours and you’ll be able to create more replies.”

213

I sugget to remove

dtparam=spi=on
dtoverlay=tft35a:rotate=270

from “/boot/config.txt”.

Do you need rotate=270 to get the display oriented to your needs?

If so, add rotate=270 to dtoverlay=tft35a in “/boot/userconfig.txt”. Then try changing Option “Calibration” “3936 227 268 3880” in “/etc/X11/xorg.conf.d/99-calibration.conf” to Option "Calibration" "227 3936 3880 268" and set Option “SwapAxes” “1” according to the values for 270 deg. touch rotation from the goodtft repo (99-calibration.conf-35-270).

If not, try changing Option “Calibration” “3936 227 268 3880” in “/etc/X11/xorg.conf.d/99-calibration.conf” to Option "Calibration" "268 3880 227 3936" according to the values for 0 deg. touch rotation from the goodtft repo (99-calibration.conf-35-0).

Reboot.

214

Changed rotation configs to 0 as suggested.
Now the cursor up and down as I move the stylus right and left across the screen and left and right when I move the stylus up and down so it appears they are 90° off. The cursor never moves out of the upper left quadrant of the screen.

cat /etc/X11/xorg.conf.d/99-calibration.conf
Section “InputClass”
Identifier “calibration”
MatchProduct “ADS7846 Touchscreen”
Option “Calibration” “268 3880 227 3936”
Option “SwapAxes” “0”
Driver “evdev”
EndSection

cat /boot/userconfig.txt
'# Add your custom config.txt options to this file, which will be preserved during updates
dtparam=spi=on
dtoverlay=tft35a
#:rotate=270

I think it is time to throw in the towel on this one.

215

Now I would set

Option "SwapAxes" "1"

and reboot.

How big is this area approximately?

216

I just tried these changes.

cat /boot/userconfig.txt
'# Add your custom config.txt options to this file, which will be preserved during updates
dtparam=spi=on
dtoverlay=tft35a:rotate=90

cat /etc/X11/xorg.conf.d/99-calibration.conf
Section “InputClass”
Identifier “calibration”
MatchProduct “ADS7846 Touchscreen”
Option “Calibration” “3936 227 268 3880”
Option “SwapAxes” “1”
Driver “evdev”
EndSection

Now the cursor follows the stylus but only in the upper right quadrant. Moving the stylus out that area, the cursor moves but does not leave the upper right.

I feel like this is an improvement.
Any other ideas?

Should I install xinput_calibrator again?

217

That’s good, but is the display orientation right?

How big is that area?

Hard to say, if the values generated by xinput_calibrator would be working. The values you posted above look strange IMHO.

What you could try before using xinput_calibrator is exchanging the overlay for wavershare35a-overlay.dtb.

218

I can live with the display orientation for now.

The area is ≈ 0.25% of the display.

with waveshare35a.dtb the screen appears but there is no touch function (no cursor or input at all).

cat /dev/input/event* returns nothing.

219

Ok, since that doesn’t seem to help change back to tft35a. After a reboot, please post the result of

cat /var/log/Xorg.0.log

220

Sorry for taking so long to get back to you.

I think we’re onto something.
See the end of the file: evdev: ADS7846 Touchscreen: Unable to query fd: Inappropriate ioctl for device.

I will try not loading edev and send the log without it.

ALSO THIS SYSTEM REPORTS “Sorry, new users can only put 2 links in a post” because it interprets anything with ‘.___’ in a string as link so I took them out. Very annoying.

Ok, then remove the line Driver "evdev"possibly being present in /etc/X11/xorg.conf.d/99-calibration.conf and delete or rename 45-evdev.conf in /usr/share/X11/xorg.conf.d. Also make sure you have 40-libinput.conf in /usr/share/X11/xorg.conf.d.

Maybe also uninstall xserver-xorg-input-evdev and xinput-calibrator

apt-get -y purge --auto-remove xserver-xorg-input-evdev
apt-get -y purge --auto-remove xinput-calibrator

OK, now the mouse remains in the upper left quadrant. It seems the axis is wrong. When I move the stylus up to down the cursor moves from left to right and left to right moves the cursor down to up.

I had no time to test very much but please create a file 99-swapxy.conf and fill it with

Section "InputClass"
        Identifier "SwapXY"
        Option "TransformationMatrix" "0 1 0 1 0 0 0 0 1"
        MatchIsTouchscreen "on"
EndSection

Save the file and restart the plugin or maybe reboot Volumio. It it works, it would only correct the swapped axes not size or position of the touch sensitive area.

You might also try to rename /etc/X11/xorg.conf.d/99-calibration.conf but according to my expectation, this should have no effect.

224

i would like to have a chance too cuz nothing worked for me:)) only black screen on my lcd…

225

I need more info:

What is the brand and exact model name of your display?

What is your Volumio version?

Are you on a fresh Volumio system?

With the Touch Display plugin enabled what is the output of

cat /var/log/Xorg.0.log

226
