VNC page coming without CSS

[DineshGuptaa]

Hi All,

I have installed the system on Ubuntu 18.04 and create docker build and that I ran make run, but page is coming without CSS. I am unable to see the proper desktop.

Thanks,

[fcwu]

May you use 127.0.0.1? Is any reverse proxy in front of the container? May you open Chrome's developer tool to check what connections are unreachable? What docker image ID are you using?

Hi Fcwu,
Thanks for quick reply.

My Ubuntu 18.04 server on VMware. That's why I am using IP. I am using ldxe-vnc as image tag. When starting Image using run command then bash is not coming instead of log coming. I how may I debug.
Below output I am getting when running the docker images

Do you build by yourself? If not,
do docker pull dorowu/ubuntu-desktop-lxde-vnc again

here is my docker image ID

docker images|grep dorowu/ubuntu-desktop-lxde-vnc   
dorowu/ubuntu-desktop-lxde-vnc                       latest                7f8aba5a9711        3 weeks ago         1.19GB

Hi fcwu,

I pulled the the image and run, it working fine. Then what is the wrong with building image. Please guide me. I provided logs previously.

second thing docker is not running in background. So that after executing startup script it not leaving command prompt for us.

Please guide me .

Thanks,

[fcwu]

first question: git clone --recursive .... You have to clone submodule too.

Update this line, https://github.com/fcwu/docker-ubuntu-vnc-desktop/blob/master/image/etc/supervisor/conf.d/supervisord.conf#L30
to
command=/usr/bin/openbox --startup /etc/xdg/openbox/autostart

You may append firefox & to /etc/xdg/openbox/autostart

[fcwu]

Support OPENBOX_ARGS for appending "--startup /etc/..." without modifying image

[Menziess]

I've found that when running the container using the new OPENBOX_ARGS environment variable, the supervisord.conf file is modified each time the container restarts, thus resulting in accumulating lines, such as:

[program:wm]
priority=15
command=/usr/bin/openbox --startup firefox --startup firefox --startup firefox command=/usr/bin/openbox --startup firefox --startup firefox --startup firefox command=/usr/bin/openbox --startup firefox --startup firefox --startup firefox command=/usr/bin/openbox --startup firefox --startup firefox
environment=DISPLAY=":1",HOME="/root",USER="root"

.. after restarting the container 4 times.

In addition, I have not had any luck on actually running firefox on container startup.

Hello @fcwu. Can I add bash script to /etc/xdg/openbox/autostart or some command? Need to run some GUI app with command roslaunch package some.launch. Need to run it automatically when user connects to 127.0.0.1:6080. Thanks

[fcwu]

@Menziess fixed in latest version

[Menziess]

Just responding for whoever else wants to open a particular webpage on startup:

docker run -d --rm --name gui \
  -e OPENBOX_ARGS='--startup "/usr/bin/firefox http://menziess.github.io"' \
  -p 6080:80 -p 5900:5900 \
  dorowu/ubuntu-desktop-lxde-vnc:bionic

And potentially for my own reference at some point. Thanks @fcwu

[bushev]

Hey @fcwu,

As I understand that feature correctly, it starts a command when the user logins with a web VNC client. Is that possible to start the GUI app when a container starts?

Use case: I need to automate a UI app, and I don't have any users to interact with a web GUI.

Thanks!
