White screen with mouse cursor and then restarts - every two seconds

[mishoboss]

Installed it on armbian on Orange Pi 4 LTS and I get process restarts every two seconds. I see a white screen with the mouse cursor for a fraction of the second before it restarts the process.

chromium-kiosk system_info shows this:

orangepi4:~$ chromium-kiosk system_info

subprocess.CalledProcessError: Command '['xrandr', '--listactivemonitors']' returned non-zero exit status 1.

what does xrandr --listactivemonitors when run under chromium-kiosk user?

@Salamek, I get this:

Hi @Salamek, please ping if you need more info. It's practically unusable now.

@mishoboss hi sorry for the late response, i had my focus on https://github.com/Salamek/qiosk...

chromium-kiosk system_info works only when X session is running correctly, and since it looks like it crashes all the time, no X session is created so that is why there is no active display...

for some reason calling exec chromium-kiosk run --config_prod in /home/chromium-kiosk/.xinitrc crashes...

You may try to replace that line^ with exec chromium to start the x session correctly with normal chromium (we do this so we can debug why chromium-kiosk is not starting)

After that try to run chromium-kiosk run --config_prod from terminal under chromium-kiosk user... you should get crash backtrace...

Hi @Salamek

I notice the same on a Raspberry Pi 4 with newest kernel. It starts, show cursor, then shortly a white page and closes as a loop.

Any idea?

@d3dx9 hi

i was able to reproduce this issue on RPI3B+ with latest raspbian, it looks like chromium package is broken on Rpi, raspbian provides its own package named chromium-browser that works, chromium-kiosk:1.0.6 attempts to load chromium-browser first...

so do

apt update && apt upgrade && apt install chromium-browser

That should fix it on latest rasbian...

Perfect, that works :) Thank you!
