Everything works but the URL switching...

Fresh build, latest 32 Bit OS release on a Pi3+. It will display the first item in the list and just stay there. I have 3 entries in the modified list.

Can you please check if the switcher service is working?

systemctl status piosk-switcher.service

[pwillard]

Aha, yes, that seems to be failing with a connection error. "Feb 25 08:49:17 kiosk switcher.sh[1796]: Wayland connection failed
"

[debloper]

Are you running it on X11 by any chance (instead of using Wayland)?

[pwillard]

I think originally I was using X11 and then switched to Wayland. I'm going to try a fresh install and try again using Wayland.

Hi,

I've using a Pi4 with a HDMI Monitor output.
Fresh install with the newest version (the one that fixes the WebUI)
The Browser is starting, the web interface is working but the switching is not happening.

echo $XDG_SESSION_TYPE
wayland

wtype ESC
-> ESC
So wayland is working in theory

Manually hitting STRG + Tab is switching the chromium tab.

Any ideas how to fix this?
"Wayfire on Wayland" is active via raspi-config. All configurations have been done via ssh.

Need a way to replicate this.

My intuition says it's a different user than the one switcher is set up for: https://github.com/debloper/piosk/blob/main/scripts/switcher.sh#L6

You can check if it's the UID 1000 that's running the desktop session with:

id -u ${whoami}

Still, it's just a wild guess.

May need more information to consistently reproduce it, in order to resolve it.

It's sadly 1000 so that's not the error. I've checked it beforehand as I've seen it in the switcher code.
Done a fresh install via raspberry pi imager (Raspberry Pi OS 32-Bit)
Than changed to wayland via sudo raspi-config and done a reboot.
After hat I've installed piosk via the terminal directly on the pi.
Rebooted and after the installation everything starting normally but the switcher still getting this error.

[GWENiklas]

When I run the script manually (/opt/piosk/scripts/switcher.sh) it works without any problems.
I than klick in the browser and everything is fine. So it must be something that the script is not working directly via systemctl correctly.

Edit: I have to both start the runner and the switcher directly, not via systemctl.

[debloper]

Do you have logs from the installation, where it's trying to start the service(s)... if it faced any issue trying to setup the service, we may get some lead as to what's causing the issue.

[debloper]

Tried looking at others facing similar issue and hopefully some leads to solutions, but no dice:

Hi! I had the same issue on a fresh Raspberry Pi OS installation. XiOSK displayed the first page in Chromium, but never switched tabs. Tab switching worked if I opened Chromium manually before starting XiOSK.

What fixed it for me was forcing the Chromium instance launched by XiOSK to use Wayland.

In /opt/xiosk/scripts/runtime/runner.sh, add:

chromium \
  --ozone-platform=wayland \
  $URLS \
  ...

Then run sudo systemctl edit xiosk-runner.service and add the following above the “Edits below this comment will be discarded” line:

[Service]
Environment=WAYLAND_DISPLAY=wayland-0

Save the file, run sudo systemctl daemon-reload, and reboot so Chromium starts as a new process. XiOSK now switches tabs automatically after boot on my Raspberry Pi 4.

I haven't yet verified this, but this appears to be getting to the root cause.

Do you have multiple compositors installed? If chrominum needs to be specifically configured to use wayland, I'm curious to know what is it using otherwise?

And yes... if the window is not managed by wayland, then ofcourse it won't listen to wayfire's inputs.

Note

I'm marking this as a solution, so that people having this issue can find it faster to give this a try & report back.

Once sufficient anecdotes lead to the same conclusions, we'll go ahead and make the change to the code itself. The reason to not make that change up front is because this is an edge case, so for most people the solution doesn't add anything, but if this breaks something, then they'll all suffer from it. So, let's take small steps.
