With the startup, I was referring to the RPI starting / booting up from being turned off. I noticed that the issue only happens from the RPI starting up and on the first instance a command is run. The next time a command is run, the command executes without issue. The main problem is the xdotool command not being executed on this first instance. However, the page is loaded.

Also, I do have TriggerCMD installed as a background agent using that command and I do have xhost+ addeed to the end of the /etc/profile

I tested it on my Raspberry Pi, except I used DISPLAY=:0 instead of DISPLAY=0.0.

"su - pi -c 'export DISPLAY=:0; /usr/bin/chromium-browser https://www.yt.com/subscriptions/; sleep 5; xdotool mousemove 300 400; xdotool click 1;'"

It worked every time after I ran triggercmdagent as root on my Raspberry Pi.

You wrote, "The first its run after startup, ..." What's startup? Do you mean startup of the triggercmd agent, or startup of the Raspberry Pi?

Edit: I just realized you're probably having your RPi login automatically as pi, and you've installed the background agent. I'll try that next.

I tried it and it works every time for me. I installed the background agent with this command:

/usr/share/triggercmdagent/app/src/installdaemon.sh

I switched the "ground" field to "background" of course, so my entry looks like this:

    {
      "trigger": "Test",
      "command": "su - pi -c 'export DISPLAY=:0; /usr/bin/chromium-browser https://www.yt.com/subscriptions/; sleep 5; xdotool mousemove 300 400; xdotool click 1'",
      "ground": "background",
      "voice": "test",
      "allowParams": "false"
    }

I also added xhost + to the end of my /etc/profile so it's enabled during boot.

The command I am trying to run is:
"su - pi -c 'export DISPLAY=0.0; /usr/bin/chromium-browser https://www.yt.com/subscriptions/; sleep 5; xdotool mousemove 300 400; xdotool click 1;'"

The first its run after startup, nothing happens. If I run the same command again, it executes without issue. I tried to tinker with it this weekend to save some time on diagnostics, but the same issue continues to persist.

If it still doesn't work, let me know. I'll setup one of my Pi's with XWindows and see if I can figure it out.

Add this line to your /etc/profile file:

xhost +

I think that will make it persist.

Hello Russ,

I hope you are doing well! I had an issue arise with "xhost +". Previously, my scripts would run using xdotool without issue. I would simply say the particular command (through assistant or wherever) and the xdotool command would be executed. Now, I can only get the xdotool commands executed after I type "xhost +" in the linux command terminal, but not after the initial startup of the Raspberry Pi.

I am curently running a Raspberry Pi 4 with debian (i can't recall which version but can provide the specifics if necessary). I recently updated through apt-get etc and that is when the issue arose. Thank you in advance and any help would be much appreciated.

su - pi -c 'export DISPLAY=:0.0; /usr/bin/chromium https://google.com'

"command":"echo pi | sudo -S su pi-c '/usr/bin/<app-location>'"

I tried the same command with chromium (and with --no-sandbox) and nothing happens (also tried with the export DISPLAY command). Is there a way to do this at all? I just wanted to launch a website from user and still have access to what I saved on the user chromium? I tried --user-data-dir and --add-user commands as well.

DISPLAY=:0.0; xdotool mousemove 500 500

I just had one question. Is it possible to chain these commands in one line in the TriggerCMD command line? so for example "command":"export DISPLAY=:0.0 | xdotool mousemove 500 500" or something along those lines. I was just wondering for the sake of minimizing the number of scripts for certain things.

Here's how to fix it:

• In your bash script, add this command before it runs your Python script:
  export DISPLAY=:0.0
• In one of your bash shells running as the pi user, run:
  xhost +

By default, root doesn't have a DISPLAY variable set, so xdotool doesn't know what X windows to talk to.

X windows also doesn't allow other users to interact with the X windows desktop by default. That xhost + command allows it.

One thing to keep in mind - if you're running a command in the background service, it will run as root, so will have root's environment variables. The pi user has a DISPLAY variable set, but root doesn't have it by default.

import subprocess
subprocess.call(["xdotool", "mousemove", "945", "132"])

I basically took it from here on stackoverflow - https://stackoverflow.com/questions/9681959/how-can-i-use-xdotool-from-within-a-python-module-script/44608709. This was just something basic for now to make sure it was working okay with TriggerCMD. The script executes and the cursor moves when called from console or through an editor. With TriggerCMD, it doesn't get launched for some reason, but the append to txt file still happens.

If you want to share your python script I might be able to figure out what's happening with xdotools.

So after the test.py worked, I tried to change the script to just having an xdotools command. I tried it and that particular line of code is not being executed. I then tried the original test.py with the line added at the bottom. The script appended into the tmp folder again but did not execute the line of code with xdotools in it.

Thank you for the help so far though. I am glad that at least the appending to file is working now

My suggestion at this point is to repeat that experiment, but keep the bash and python script super simple, and output to a file in /tmp from both so you can see if either one ran. So you could make this your bash script:

#!/bin/bash
echo "Hello from bash" >> /tmp/bash.log
/usr/bin/env python3 /root/test.py

You could use the test.py example above. It's simple and writes a log file.

Don't forget to make the bash script executable with chmod +x test.sh

If we can get a super simple python script to run, that would narrow down the problem.

The script I had running is simply to perform a button click (actually just to pause a video). I even tried a script that outputs appends to a file but still nothing. I even tried EXPORT.DISPLAY=0.0 to no avail.

I assumed the issue was down to the agent being in root and the applications being under the user (based on previous posts). I previously had an issue of launching applications but I found the following command did the trick

"command":"echo user | sudo -S su user -c '<app-location>'"

For some reason though, this doesn't work for python scripts. So <'python script.py'> or even <'python' script.py> or with the python location obtained from "which python". It is the same with python3. I even tried bash scripts and still nothing.

{"trigger":"python test","command":"python3 /root/test.py","ground":"background","voice":""},

I also tried it with python 2.7 with this commands.json entry:

{"trigger":"python test","command":"python /root/test.py","ground":"background","voice":""},

This is my test python script:

f = open("/tmp/test.txt", "a")
f.write("Now the file has more content!")
f.close()

Maybe you're setting the ground to foreground? Usually on a Raspberry Pi it needs to be background because it's running in the background service.
