nvidia-docker-novnc's Issues

Unable to open display message from run.sh

Hello Folks,

When I execute the run.sh script, I see the following output:

root@ip-192-168-0-37:/home/ubuntu/nvidia-docker-novnc# ./run.sh
+ chmod -f 777 /tmp/.X11-unix
+ touch /root/.Xauthority
+ xauth generate :0 . trusted
No protocol specified
xauth: (argv):1:  unable to open display ":0".

When I docker exec to the running container, the lightdm service cannot start.

Has anyone else run into this? If so, how did you solve it? Thanks!

How to setup network / url access to instance correctly?

It would be great to have documentation in the README. that refers to how networking should be setup to the instance.

When executing /run.sh, the output ends in something like this:

Navigate to this URL:

    http://5e1e573deXYZ:40001/vnc.html?host=5e1e573deXYZ&port=40001

On google cloud, does one just open port 40001 and access the external IP address, like actually navigating to http://216.3.128.12:40001/vnc.html?host=216.3.128.12&port=40001 (just an example)?

Or is url mapping needed?

How much disk space is needed?

I started the following GCP instance but seem to run out of disk space. I would love for this to be part of the readme!

The instance has 10GB of disk space.

TurboVNC gray screen error

Hello, I know this repo was created a few years ago. I was able to successfully build the image and run it. However I am not sure why I am getting a gray screen. I did have to comment out Light-locker and Xfce-power manager due to errors. It looks like those two are not compatible with current Ubuntu 20.04. I would like to run this on Ubuntu 20.04. Any ideas on how I can go about this?
