@toschneck 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 :wink:

codlin commented 7 years ago

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

toschneck commented 7 years ago

@codlin thx for finding! I fixed it in the startup script see, https://github.com/ConSol/docker-headless-vnc-container/commit/fcb0b2def5cab36ec184aab46cab2fd0b4598e28. 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
