@BJK LXDE/autostart is running as root I think…

pm2 autostart is NOT running as root, so u have to use sudo

@Snille

Thank you! :beaming_face_with_smiling_eyes:
Now, after your precise suggestions, I did read up on the autostart for Raspberry:
https://forums.raspberrypi.com/viewtopic.php?t=313191
https://forums.raspberrypi.com/viewtopic.php?f=66&t=294014

and using:
“sudo nano /etc/xdg/lxsession/LXDE-pi/autostart”

I pasted my line at the end of the the autostart:
@/home/pi/xin.sh
and then saved the file

In the xin.sh file, I have:
line1: #!/bin/bash
line 2: DISPLAY=:0.0 xinput --set-prop “Multi touch Multi touch overlay device” “Coordinate Transformation Matrix” 0 -1 1 1 0 0 0 0 1

So, just two lines and "line1or2: " is not part of the file :smirking_face: (and - as you said - I do have a bit different coordinate compared to you)

AND now it WORKS! Thank you !

@BJK I don’t start the xin.sh (with pm2). if you read in the xin.sh file you will find instructions how I did it… :) Here you can download the xin.sh.

The script (if you don’t want to download it):

#!/bin/bash

# Before I just tested with the xinput command directly in the autostart file, but that did not work. So now instead I just created a script called xin.sh.
# nano ~/xin.sh
# Then added
# DISPLAY=:0.0 xinput --set-prop "Multi touch Multi touch overlay device" "Coordinate Transformation Matrix" 0 1 0 -1 0 1 0 0 1
# There should actually be 3 spaces between “Multi touch” and “Multi touch overlay device”. For some reason the board removes the extra spaces here.
#
# You can actually find the “name” of the device with this commandDISPLAY=:0.0 xinput list
# Shows something like this:
#
# Virtual core pointer id=2 [master pointer (3)]
#   Virtual core XTEST pointer id=4 [slave pointer (2)]
#   Multi touch Multi touch overlay device id=6 [slave pointer (2)]
# Virtual core keyboard id=3 [master keyboard (2)]
# Virtual core XTEST keyboard id=5 [slave keyboard (3)]
#
# Depending on what you have connected to your RPi. 🙂
# 
# So, after creating the xin.sh I added that to the autostart file for LXDE:
# Like this:
# nano ~/.config/lxsession/LXDE-pi/autostart
# Added at the end of the file.
# @/home/pi/xin.sh
# Restarted and it works.
#
DISPLAY=:0.0 xinput --set-prop "Multi touch   Multi touch overlay device" "Coordinate Transformation Matrix" 0 1 0 -1 0 1 0 0 1

You have to figure out your own “matrix” of course… :) Not sure if mine is the same…

@BJK pm2’s JOB is to start and run stuff AND KEEP it running…

so, if it ends. pm2 will start it back up…

and if it errors too many times too fast it will stop restarting…

@BJK
and you were logged on as user pi, right?
Well, instead of user pi, I am user Bo. So my home directory is like home/Bo/MagicMirror/modules…
But any idea about the xin.sh error? Would it help to let pm2 just run the xin.sh once?

@BJK

Regarding: “we’re you running as root ( or using sudo ) when u did the pm2 start xin.sh?”

I just wrote “pm2 start xin.sh”,and then “pm2 start mm.sh” and then at last “pm2 save”

Should I have used “sudo pm2 start xin.sh” ?

@BJK first

do
pm2 save

to sync the disk list with the memory list of things pm2 manages

then do

pm2 info 0

to get the startup info from the task definition

we’re you running as root ( or using sudo ) when u did the pm2 start xin.sh?

@sdetweil

Well, I start the xin.sh with PM2 and it works with calibrating the IR-frame:

xin.sh:
#!/bin/bash
DISPLAY=:0.0 xinput --set-prop “Multi touch Multi touch overlay device” “Coordinate Transformation Matrix” 0 -1 1 1 0 0 0 0 1

However, after the mm.sh (the MagicMirror) has started, then when I go back to Raspberry disktop the the Calibration is off again. If I then run the xin.sh with “pm2 start xin.sh” in a terminal window then the calibration is okay again.

This is the error that I get from pm2 log file:

Should I do something else with pm2 or run the xin.sh in an other way?

It would be so nice to have i done automatically 😁

the mm.sh file:
cd ~/MagicMirror
DISPLAY=:0 npm start

@Snille Hi Snille
I have had greate use of xin.sh file to run at start. It contained the:
“DISPLAY=:0.0 xinput --set-prop “Multi touch Multi touch overlay device” “Coordinate Transformation Matrix” 0 1 0 -1 0 1 0 0 1”
However, now using the pm2 start xin.sh for automatic start, I get an error in the pm2 log
What do you use to correct the ir-frame ?

I have a 24" one that after I bought it found out that it will not work in Linux so my only option is to install MM on Windows … ugh. So when I can come across a NUC or something small I will until then …

@core but this is effectively the same as the ir frame… the special touchfoil does the work… NOT the monitor…

Ok, but a PCAP Touchfoil under the glass, mounted between a LED display and the Mirroview, will work for sure (asked Pilkington and the company selling the foil).

@core said in Magic Mirror with touchscreen Display/Monitor:

That’s why i am looking for a touch display which can be mounted under the glass.

that doesn’t exist. the monitor is dependent on human skin resistance (try it with a glove on)
the mirror glass would block that

Hi,

thank you very much for your replies.

An IR touch overlay is unfortunately not possible in my case. The mirror is frameless and clamped in 4 holders (2 above and 2 at the bottom). That’s why i am looking for a touch display which can be mounted under the glass.

Best regards

@core I also used a IR-Frame in my build. Works very well if you just want “simple” point and click and/or point and drag (even with two fingers)… I have not tested it with more advanced stuff. :) But for the MM it’s great. You can read about my build here and underneath the picture, you can find a link to a full photo album with pictures and text to all pictures about what you see. :)
