Black screen on VNC

[AlexMihe]

Hello,

I've been running this docker for a year now, but till recently when I start the VNC I only get a black screen with a cursor (that I cannot move).

I haven't find any solution yet. I've got three different dockers running the same image and I've got the same problem starting at the same moment.

Would anyone have an idea?

Thank you!

I am having the same issue which I only noticed today. I recently was updating other containers on my system and decided to check on my crashplan container to see if everything was working and am only getting a blank screen.

I did a pull to see if there was an update and it looks like this is the image is umodified: docker pull gfjardim/crashplan Using default tag: latest latest: Pulling from gfjardim/crashplan Digest: sha256:268edad41647865733ef5be793ae6d853714f140615222fc5030300e0f76d28f Status: Image is up to date for gfjardim/crashplan:latest

Here's what I'm seeing in my journalctl for the docker-crashplan service I've created:

That doesn't look super great above, but the applicable shorter logs have the following error on startup that otherwise doesn't seem to have any specific affect:

"ERROR: openbox-xdg-autostart requires PyXDG to be installed"
