Setup.sh running problem
Hi, friend! Thanks for your brilliant job first. But I have encountered several problem when running setup.sh. Could you please help me?
I run exactly the same hardware settings and software settings but problems occurs.
Problem may caused by errors in previous steps as follows: (I am not sure)
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 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.
Error:
Unpacking gconf2-common (3.2.6-3ubuntu6) ...
dpkg: unrecoverable fatal error, aborting:
unable to flush /var/lib/dpkg/updates/tmp.i after padding: No space left on device

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?
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?
