Running a kiosk on Ubuntu Classic

jimmywa · December 11, 2019, 12:45pm

Sorry, the fullscreen is end result what I want. I think that it is necessary to explain my whole story.
My goal is run an electron application in kiosk. The steps look like below:

setup machine with ubuntu desktop 18.04.03
build an electron snap application. I build the application from here
SSHd my machine and test whether electron app is ok in kiosk.

sudo snap install mir-kiosk
sudo snap set mir-kiosk daemon=true # this comes from you suggestion at https://discourse.ubuntu.com/t/failed-to-find-platform-for-current-system-when-starting-mir-kiosk/10124/19?u=jimmywa
sudo snap restart mir-kiosk
# at here I can see a black fullscreen
sudo snap connect electron-hello-world-kiosk:wayland
sudo snap restart electron-hello-world-kiosk
# at here I expect that I can see a hello-world page, but I can not.
# in case of my app is a wrong app, I also test the `mir-kiosk-apps`
sudo snap install --edge mir-kiosk-apps
sudo snap connect mir-kiosk-apps:wayland
sudo snap restart mir-kiosk-apps
# at here I expect that I can see the content as same as the picture in this post but I can not.

so my question is how to run an electron application in kiosk with fullscreen! This is my whole story.
I learn kiosk at recently, so can you give me some suggestion for the goal?

You are digressing somewhat from the topic of this post: running mir-kiosk within your desktop environment.

What you are trying is closer to Install mir-kiosk and chromium-mir-kiosk under Ubuntu 18.04 Server (I know you’re not using chromium-mir-kiosk or Ubuntu Server, but this is about setup on a classic system.)

When you say “at here I can see a black fullscreen” are you seeing the Orange “splash” as mir-kiosk starts and the cursor? Or just a black screen? What do you see in sudo snap logs -n 50 mir-kiosk?

Just a black screen. About the snap log, I want to say sorry because I get a black screen when I restart my machine. But from your reply, I figured out that the desktop os is not a classic system. Right?
I will try the Ubuntu 18.04 Server. Thank you very much.

Then mir-kiosk is not running which would explain why client snaps fail to work.

That is probably because mir-kiosk tries to start and fails, the logs may tell us why. You should be able to VT switch (Ctrl-Alt-F1) to the greeter and log in normally. If that fails ssh in from another machine and disable the daemon:

sudo snap set mir-kiosk daemon=false

Both Ubuntu Desktop and Ubuntu Server are “classic” systems, as are Fedora, Arch etc. the distinction snapd makes is between “core” (i.e. Ubuntu Core) and “classic” systems.

I have reproduced the black scree and get the mir-kiosk log:

And my reproducing step look like:

Another thing I want to say: I setup the machine with vmware fusion. I do not know if this is related to black screen.

1.

I test the another snap application: chromium-mir-kiosk. When I install / connect / restart it, I see the screen which looks like below:

All looks very good, but when I click the menu in the kiosk screen the screen goes into black. I get the kiosk and app log:

From the log I find the error in chromium-mir-kiosk when I click the page. The details logs like below:

I’ve tested your website using wpe-webkit-mir-kiosk and mir-kiosk on a “classic” Ubuntu 19.10 Desktop system. It works for me (and ought to work for any “classic” system):

sudo snap install mir-kiosk
sudo snap set mir-kiosk daemon=true
sudo snap restart mir-kiosk
# Orange "splash" & black screen with cursor
sudo snap install --beta wpe-webkit-mir-kiosk
sudo snap connect wpe-webkit-mir-kiosk:wayland
sudo snap set wpe-webkit-mir-kiosk url=https://www.neuralgalaxy.com
# Your site displays and works
