Hi, I create a container with command 'docker run --name AAA -d -p 5902: 5901 -p 6902: 6901 consol/ubuntu-xfce-vnc',
then I put some documents to container, and commit container
docker commit AAA AAA:test
then I create new container using this new images:
docker run --name BBB -d -p 5903: 5901 -p 6903: 6901 AAA:test
but I cannot connet this container via VNC view,
I found some ps didn't start:

Hi,

I found the problem, it troubes me one whole day.
Into the new container, and delete /tmp/.*
then exit and restart it, vnvserver can be started normally.
I tried to build images earlier, I use 'rm -f /tmp/* to delete files in Dockfile, but no effect, this command didn't delete .*
Now I build a new images and vnc is ok.
Thanks.

Dockfile:

I'm also see this, I already try to fix it. give me an hour or so 😉

[codlin]

Thank you very much for your quick response. You're greate!

[toschneck]

@codlin thx for finding! I fixed it in the startup script see, fcb0b2d.
This fixes and the other new features like usermod are currently all in the dev branch.
I will try to release a new version soon. Until this you can use the dev taged image:
docker run ... consol/ubuntu-xfce-vnc:dev
