Kiosk-mode browser: no image

[amueller]

We are using a Colibri iMX6 with the Viola Carrier Board and the official HDMI adapter. We have connected two different displays, a PC monitor and a 5" HDMI display, the behavior is the same in both cases.
On startup, the monitors show the Torizon boot splash, but the we do not get an image from the kiosk mode browser, the display remains dark. We have used two different docker-compose files, the demo containers that come with a fresh installation, and the grafana example (Using Multiple Containers with TorizonCore | Toradex Developer Center). In both cases, portainer and grafana are accessible via a web browser from a different PC, but fail to show up on the display connected to the module. The display remains dark, but when connecting a mouse, a mouse cursor shows up and can be moved. When stopping these containers, we see a login prompt on the local display.

Here are the logs from starting the demo-containers manually with docker-compose up:

Thank you for your help. If you need any additional information, please let me know!

Greetings @amueller,

So by default all graphical containers provided by us are designed to run using the system’s “default” display interface. For Colibri modules the default is parallel RGB/VGA. We make this distinction in the Dockerfile of our wayland container which our kiosk container builds on top of. You can see this here: debian-docker-images/Dockerfile at buster · toradex/debian-docker-images · GitHub

This explains why you see a black screen/mouse cursor only. This is actually the weston container doing that. Based off your logs we can see that weston grabs the correct HDMI display, display 1. But the kiosk container tries to grab display 0, which is the parallel RGB/VGA interface. This is probably due to us explicitly defining the display in wayland as I said above.

As for fixing this, you’ll need to rebuild the kiosk container and change the display variable to use display 1. I already linked the Dockerfile source for our wayland container above so here’s our Dockerfile for the kiosk container:

# First stage download virtual keyboard
ARG BASE_IMAGE=torizon/arm32v7-debian-wayland-base

FROM $BASE_IMAGE:latest
RUN apt-get -y update && \
    apt-get install -y --no-install-recommends wget

WORKDIR /extension

# Download the virtual keyboard from gitlab
RUN wget --no-check-certificate https://gitlab.int.toradex.com/rd/torizon-core/chrome-virtual-keyboard/-/archive/master/chrome-virtual-keyboard-master.tar.gz && tar -xf chrome-virtual-keyboard-master.tar.gz

# Second stage build final container
FROM $BASE_IMAGE:latest

# Needs to come after FROM!
ARG BUILD_TYPE=wayland

RUN test "$BUILD_TYPE" = "x11" && \
        sed -i '/feeds.toradex.com/d' /etc/apt/sources.list || true

RUN apt-get -y update && \
    apt-get install -y --no-install-recommends chromium chromium-sandbox && \
    apt-get clean && apt-get autoremove && \
    update-mime-database /usr/share/mime && \
    rm -rf /var/lib/apt/lists/*

# Copy the virtual keyboard extension from the first stage
COPY --from=0 /extension/chrome-virtual-keyboard-master /chrome-extensions/chrome-virtual-keyboard

COPY start-browser.sh /usr/bin/start-browser

USER torizon

ENV LIBGL_ALWAYS_SOFTWARE=1
ENV DISPLAY=:0

ENTRYPOINT ["/usr/bin/start-browser"]
CMD ["http://www.toradex.com"]

Unfortunately I can’t verify this solution for you ahead of time as I don’t have the HDMI adapter available. But I’m fairly confident it should work since as we can see Weston used display 1 just fine. But please let me know if there are any issues/questions about this solution.

Best Regards,
Jeremias

Hello Jeremias,

unfortunately, I am struggling with building the containers. I got the Dockerfiles from above (for kiosk) and from github (weston) and copied them onto the imx6. However, the builds abort when calling apt-get:

Is this a ressource issue? I currently only have the 256MB single core available.

Building the weston image on my development PC works. The Dockerfile for kiosk fails since it cannot reach the gitlab server: https://gitlab.int.toradex.com Is this possibly an internal one?
Also, the start-browser.sh is missing but I was able to extract that from a running container:
#!/bin/sh

# default url
url="www.toradex.com"

# default parms for kiosk mode
chromium_parms_base="--test-type --allow-insecure-localhost --disable-notifications --check-for-update-interval=315360000 "
chromium_parms="--kiosk "

for arg in "$@"
do
    case $arg in
    --window-mode)
        chromium_parms="--start-maximized --app="
        shift
        ;;
    --browser-mode)
        chromium_parms="--start-maximized "
        shift
    esac
done

if [ ! -z "$1" ]; then
    url=$1
fi

exec chromium $chromium_parms_base $chromium_parms$url

Unfortunately, the contaier fail to start: weston comes up briefly, but shuts down again without an error message. kiosk reports a permission error for the start-browser script. I tried adding a line
RUN chown torizon:torizon /usr/bin/start-browser or uncommenting the USER torizon line in the Dockerfile, but the result is the same:

Apologies the Kiosk container source hasn’t been fully published to the public yet, we intend to do this though which is why I have to share the source with you directly rather than pointing to a github repo.

Anyways as for the permission error with the script I think you’re missing the shebang at the top of the script. Here’s the full script from the source:

#!/bin/sh

# default url
url="www.toradex.com"

# default parms for kiosk mode
chromium_parms_base="--test-type --allow-insecure-localhost --disable-notifications --check-for-update-interval=315360000 "
chromium_parms="--kiosk "
# Additional params should be stacked chromium_parms_extended="$chromium_params_extended ..."
chromium_parms_extended=""

for arg in "$@"
do
    case $arg in
    --window-mode)
        chromium_parms="--start-maximized --app="
        shift
        ;;
    --browser-mode)
        chromium_parms="--start-maximized "
        shift
        ;;
    --virtual-keyboard)
        # Load the virtual keyboard
        chromium_parms_extended="$chromium_parms_extended --load-extension=/chrome-extensions/chrome-virtual-keyboard"
        shift
        ;;
    esac
done

if [ ! -z "$1" ]; then
    url=$1
fi

exec chromium $chromium_parms_base $chromium_parms_extended $chromium_parms$url

As for the apt error, I’ve never seen it just abort like that before, but then again I typically build my Dockerfiles off the device and transfer them later. Perhaps it might be a performance issue on our lower-end modules. I may need to perform further testing on my side to confirm.

Best Regards,
Jeremias

Jeremias,

thanks again for the quick reply! I will be out of office next week but I will test it as soon as I’m back! Unfortunately, I have to order some extra hardware. I bought the imx6 Solo and Duo, and the Viola Carrier Board. Unfortunately, the lack of space between the pin header on the Viola Carrier and the module put a lot of strain on the foil cable, which causesd the X2 connector to break off from the Duo Module - so I’m left with the Solo only and do not want to repeat that experiment!
I will get back to you a soon as I have some more results.

Jeremias,

I was able to build my own kiosk container, but I had no luck getting the browser window on the HDMI output. Here are the steps starting with a fresh Colibri i.MX6 Dual and the Colibri Development board:

• Toradex easy-installer shows up on HDMI and VGA
• Installing Torizon Core with Evaluation Containers
• Boot-Splash shows up on HDMI and VGA
• After booting, the display is extended. The portainer window is displayed 80% on VGA, 20% on HDMI
• After another reboot, portainer window shows up on vga only. Display is extended to HDMI, I can move the mouse cursor from one to another.
• Build my-kiosk container from torizon/arm32v7-debian-wayland-base with  ENV DISPLAY=:0
• Replace image in /var/sota/storage/docker-compose/docker-compose.yml with my-kiosk
• Reboot: Again, portainer is split over both displays
• Reboot: portainer on VGA only, display is extended to hdmi
• rebuild my-kiosk with ENV DISPLAY=:0 and load it onto the module
• Reboot: black screen on both displays, I can move the mouse cursor between both, but no portainer window
• Docker ps on the module shows the kiosk-container is not running
• Bringing the docker-compose file up manually shows that my-kiosk crashes when trying to connect to display 1:

Hi @amueller,

Just to clarify so I understand correctly, in the cases where you say the display was extended. Did the Portainer UI extend at all into the HDMI screen or was the HDMI screen just black with a mouse cursor the entire time? It would appear that Wayland in the Kiosk container has issues with trying to grab display 1/the HDMI display. What happens if you disconnect the VGA display then don’t define the “DISPLAY” variable in the Dockerfile at all?

By the way do you require both VGA and HDMI interfaces or just HDMI? Because another option possibly would be to disable the VGA interface completely then see if that let’s us use HDMI more easily.

Best Regards,
Jeremias

[amueller]

Hi Jeremia,
the system behaved like a dual monitor setup with the VGA being the primary screen. After the first start, the portainer ui extended about 20% into the hdmi screen, but after a reboot, the system seemed to recognize the correct boundaries and displayed the portainer ui on the VGA screen only. However, it was clearly still a multi-monitor setup since I could move the mouse cursor from one screen to the other.

When omitting the DISPLAY variable in the kiosk container, it again tries to grab display 1 and fails. Whether VGA is connected doesn’t matter.

We do not need the VGA, so if you could tell me how to disable it, I’'ll give this a try!
Andreas

[jeremias.tx]

This is interesting behavior, seems like even with no VGA the system still defaults to that as display 0. I’ll see if I can find out more about this display behavior.

In the meantime I guess we can give disabling the VGA interface a try and see if that changes anything.

So to properly disable the VGA interface requires some changes to the device tree. The device tree that the i.MX6DL uses for the Torizon kernel is here: imx6dl-colibri-eval-v3.dts « dts « boot « arm « arch - linux-toradex.git - Linux kernel for Apalis, Colibri and Verdin modules

The timings resolution for the VGA/parallel RGB are controlled by the panel_dpi node. What we can try first is disabling this node. Luckily we have a tool in Torizon that should allow for a small device tree change such as this. See here for more info: Device Tree Overlays on Torizon | Toradex Developer Center

Currently we don’t have a pre-made overlay that disables the parallel RGB interface but it shouldn’t be too hard to make one. See here for an overlay that changes the timing and resolution of this interface: device-tree-overlays/display-edt5.7-overlay.dts at toradex_5.4.y · toradex/device-tree-overlays · GitHub

We need just set the status field to disabled so an overlay like this should work:

/dts-v1/;
/plugin/;

/ {
	compatible = "toradex,colibri-imx7d-emmc","toradex,apalis_imx6q", "toradex,colibri_imx6dl";
	fragment@0 {
		target-path = "/panel-dpi";
		__overlay__ {
			status = "disabled";			
		};
	};
};

You can use the overlay tool I linked earlier to try this out.

I’m not sure what all the effects of this will be honestly but we can disable the overlay at anytime if things get too weird.

Best Regards,
Jeremias

[amueller]

Ok, so I disabled the VGA output as follows:

• Start the development container
• save the above overly as disable-vga.dts in /device-tree-overlays/overlays
• run dtconf activate disable-vga.dts

After reboot, the torizon splash screen shows up on the hdmi screen only (used to be hdmi and vga), so it seems that worked correctly.
However, weston doesn’t come up and kiosk also fails when trying to connect to display:0

Alright then, this definitely falls under effects that I didn’t expect would happen when disabling VGA. So as you said the boot-splash and all that was now on HDMI (I assumed it was framed correctly and sized). Which means the base system recognizes that HDMI is now the default/only display option.

But now it seems the issue is in the container. Based on the logs it seems Weston registers the HDMI interface as input device events, which it did for the DPI/VGA interface previously. However where it differs seems to be that Weston thinks the interface is being removed(?) Or something similarly strange.

I’m going to need to check this with our team that works on these containers. Perhaps there’s some extra configuration I’m missing. Or possibly perhaps we need to add the functionality/feature here since I don’t think anyone’s actually tried this exact use-case yet.

In any case let me check with the team and get back to you.

Best Regards,
Jeremias

Ok, thank you for your efforts so far! Let me know, if there is anything else I can try. Unfortunately, I have a deadline coming up.

Not sure if the helps, but here is a quick update from my end:
I experimented with additional command line parameters for chromium. Since the system seems to behave like a multi-monitor setup (I can move the mouse pointer from one display to the other), I thought it should be possible to move the browser window as well. The commandline argument is --window-position=x_offs,y_offs, which I added to the “command” argument in the docker-compose file.
While this works on Windows with a multimonitor setup, unfortunately it had no effect on the i.MX6. The window showed up fullscreen on the VGA display, as before.

[jeremias.tx]

I got some feedback from the team and according to them disabling the panel_dpi node via overlay should have worked. Based on the last logs you provided the team things it’s a problem with the system touching/configuring the correct tty.

So here’s what I think we should try. First of all stop and remove all other containers on the system. Next stop Portainer from auto-starting on boot via sudo systemctl disable docker-compose. You can re-enable this later at any time.

Ok now all other containers have been cleaned up and disabled, let’s take a step back and do some tests with simple containers. Also make sure you have the overlay applied that disabled panel_dpi.

Try following the article here: Debian Containers for Torizon | Toradex Developer Center

Follow up to the first 2 docker run commands. This will have you launch a simple weston and wayland container stack with some basic graphical elements. If the weston container fails to start try using different ttys in the docker run command. i.e. by default we use --tty=/dev/tty7 but if it doesn’t work try tty6 or something. Also if it still doesn’t work try reading out the individual container logs.

Best Regards,
Jeremias

Ok, I tried this, but still no success bringing up weston. I tried /dev/tty1 to /dev/tty10.
For /dev/tty1 to /dev/tty6, the tty is in use:

/usr/bin/weston-launch: TIOCSCTTY failed - tty is in use: Operation not permitted

For /dev/tty7 and up, I seem to get the same error message as before:

docker ps shows no running container

Additionally, I noticed the following:

• atfer disabling the VGA output, the HDMI screen doesn’t show a boot splash any more but the dmesg log
• after boot, I first see a terminal login prompt on the HDMI display. When executing the first docker run as above, that is replaced by a black screen and doesn’t return even after the container terminates.

Jeremias,
do you have an update on this topic? If it helps, we could set up an online meeting with your dev team to show a live demo.
Regards,
Andreas

The team is still looking into this. This may require a change to our base containers, we’re also in the process of updating our Debian containers from buster to bullseye so there’s some churn going on there. I can try and elevate this issue with the team.

For the time being are you able to test your application/system with the VGA interface? I can assure you that it’s possible to get HDMI working in the container but to get this change may require some time.

Best Regards,
Jeremias

Thank you for the update! I have done as much as I can with the VGA display, but the demonstrator unit for our customer includes the Viola Baseboard and a display which only has an HDMI connector.
So if you could elevate the issue, I would be much obliged!
Thanks,
Andreas

Quick follow up question: I am thinking about ordering an Iris carrier board for the demonstrator. If I read the datasheet correctly, the DVI-I connector should act the same as the VGA connector on the Colibri evaluation board. And the DVI-I can easily be adapted to HDMI. Can you confirm this?
Thank You,
Andreas

[jeremias.tx]

Alright just to update I was able to get this priortized by the team, so they’ll begin working on this in our next sprint ASAP.

As for your other question in short yes the DVI-I is fed by the parallel RGB interface similar to how the VGA interface on the evaluation board is. Except as the datasheet says DVI-I interface is easier to adapt to HDMI.

Best Regards,
Jeremias
