Run Ubuntu Frame on your Device

Documentation Mir Docs

This is a quick reference for running Ubuntu Frame on a device.

Setup your device

You need either Ubuntu Core or a version of Linux supporting snaps.

  1. Setting up Ubuntu Core is described in Get Ubuntu for IoT
  2. Setting up snapd on other versions of Linux is described in Installing snapd

Follow the instructions to install Ubuntu Core/snapd and ssh into your device.

Install Ubuntu Frame

You should now have a command prompt reading something like <your‑user>@yourdevice:~$. Now install Ubuntu Frame with the following command:

$ snap install ubuntu-frame

If you are using Ubuntu Core, you can skip this next step. On other versions of Linux, Ubuntu Frame does not start by default. To change this default run the following command:

$ snap set ubuntu-frame daemon=true

Once Ubuntu Frame starts the display should show a graduated grey screen. This is the default Ubuntu Frame wallpaper. This can be changed using the “config” snap configuration option:

$ snap set ubuntu-frame config="
wallpaper-top=0x92006a
wallpaper-bottom=0xdd4814
"

The wallpaper-top and wallpaper-bottom are RGB values. There are a lot of configuration options to control the kiosk display, but they are all set using config and display (more details in REFERENCE.md)

Install a Web Kiosk

Still in your ssh session, install web kiosk:

$ snap install wpe-webkit-mir-kiosk

If you are using Ubuntu Core, you can skip this next step. On other versions of Linux, wpe-webkit-mir-kiosk does not start by default. To change this default run the following command:

$ snap connect wpe-webkit-mir-kiosk:wayland
$ snap set wpe-webkit-mir-kiosk daemon=true

Once installed and configured the display should show the WPE website.

The website can be changed using the “url” snap configuration option:

$ snap set wpe-webkit-mir-kiosk url=https://mir-server.io
$ snap start wpe-webkit-mir-kiosk

This will show the Mir Server website.

Next steps

For more detail about running and configuring Ubuntu Frame, and for resources to help build your own snaps to work with it see REFERENCE.md.

hi. I use these commands for setup web kiosk on my ubuntu 22.04 server arm64 on rapsberry pi4 but my sceen is black. thank you from you if tell me what is my problem?

Sorry, @majidkaka14 you have not provided enough information for us to help.

At what point did you get a black screen?

Did you see any error messages when you ran the commands?

Thank you for your quick response @alan_g .when i use this command:
snap set ubuntu-frame daemon=true
the black screen is displayed with a flashing pointer. I checked dmesg command and see this log:
apparmor=“DENIED” operation=“open” profile=“snap.ubuntu-frame.daemon” name="/run/user/0/" pid=3367 comm=“mkdir” requested_mask=“r” denied_mask=“r” fsuid=0 ouid=0

Can you check the ubuntu-frame log:

snap log -n 80 ubuntu-frame

I want to see if the error you see in dmsg is the actual problem. (You can avoid formatting the log using triple backquote ``` around it.)

This is your problem: Mir cannot find a display to render to. You need to enable KMS in config.txt.

I’m not sure of the exact incantation for RPi4, but here’s the corresponding information for RPi3:

https://github.com/MirServer/ubuntu-frame/issues/39#issuecomment-966308829

You can find information on RPi4 here:

https://www.raspberrypi.com/documentation/computers/configuration.html

(I think you need vc4-kms-v3d-pi4, but don’t have the kit to try it)

It was great, thank you very much for your help. yes when edit dtoverlay (in /boot/firmware/config.txt) to vc4-kms-v3d-pi4 value, it works for me. Just one more issue,
the mouse pointer does not appear on the screen. how can i fix it?

9

I suspect a problem with the driver support for hardware cursor. Try adding cursor=software to the Ubuntu Frame config option.

beyond what alan said, IIRC the pointer is dynamic, do you actually have a mouse attached ? without it it should not be shown.

Thank you, yes, it was fixed with the following line:
sudo snap set wpe-webkit-mir-kiosk cursor=software

Hi Alan
I’m tring do some “Mir on X” simulator according to “IoT Graphics with
Ubuntu Frame” document. I got a error when I used ‘ubuntu-frame&’ command. Here are message in bleow.

std::exception::what: Failed to find any platforms for current system

could you give me some suggestions. thanks.

14

@attachbingo you don’t give much of the log (each platform will show why it doesn’t work on the current system).

My first guess is that you you already have a Wayland compositor running and failed to change the WAYLAND_DISPLAY environment variable.

15

I have followed the steps in https://mir-server.io/docs/run-ubuntu-frame-on-your-device on 22.04.2 LTS and I am getting a red screen. This is a new NUC running Intel N200.

Please advise.

These are my logs:

These suggest that the problem lies with the exchange of buffers between the snaps.

Further up the logs I see:

So it may be that the problem is that the hardware is not supported by the mesa-core20 snap.

It is possible that the more recent Mesa in kisak-core20 would work. But you’d need to install it from edge and connect the snaps to it:

snap install --edge kisak-core20
snap connect ubuntu-frame:graphics-core20 kisak-core20
snap connect wpe-webkit-mir-kiosk:graphics-core20 kisak-core20

And possibly restart wpe-webkit-mir-kiosk.cog too.

17

Works, thank you so much. Should I report a bug to the mesa-core20?

PS. In case anyone wants to try the same workaround, a small change to the above commands:

snap install --edge kisak-core20
snap disconnect ubuntu-frame:graphics-core20
snap connect ubuntu-frame:graphics-core20 kisak-core20
snap connect wpe-webkit-mir-kiosk:graphics-core20 kisak-core20
18

It isn’t really a bug with that package, just that your hardware is newer than the drivers it packages from the Ubuntu archive. When the archive has newer drivers, then the package will get updated.

Hi @alan_g i use ubuntu 22.04 server version on raspberry pi4 B (8G memory)model and i can setup wpe-webkit-mir-kiosk successfully on it but its rendering is slow, how can I speed up the display?
I setup kiosk with these commands:

sudo snap install ubuntu-frame
sudo snap set ubuntu-frame daemon=true
sudo sed -i 's/dtoverlay=dwc2/dtoverlay=vc4-kms-v3d-pi4/g' /boot/firmware/config.txt
sudo snap install wpe-webkit-mir-kiosk
sudo snap connect wpe-webkit-mir-kiosk:wayland
sudo snap set wpe-webkit-mir-kiosk daemon=true 
sudo snap set wpe-webkit-mir-kiosk url=http://localhost
sudo snap start wpe-webkit-mir-kiosk
sudo snap set wpe-webkit-mir-kiosk cursor=software
20

@majidkaka14 I assume you did reboot after editing the firmware/config.txt?

In general, I don’t know how, or if it is possible, to optimise WPE webkit. As you can see in the “snap info”, it is published by Glancr:

$ snap info wpe-webkit-mir-kiosk | grep -e contact -e gitlab 
contact:   kontakt@glancr.de
