Hey there, thanks for opening this issue and for using this software! May I ask you some more details about the environment (e.g. Docker version, OS) and what is the command / docker-compose file you are using to spin this up?

Could you please tell me what is the digest of the specific desktainer Docker image you are using?

And please could you provide the content of the Xvfb log (you can find it in /var/log/supervisor inside the container)

Thanks :)

Hey there @SiNaPsEr0x, thanks for sharing your log. Based on your answers, I assume that you're running the dmotte/desktainer:2023.04.13.2110 image on arm/v7 architecture.

Unfortunately, the log is not very useful because it just tells us that there has been a segmentation fault while trying to start Xvfb.

I don't have a qnap, so I tried to run the image on this setup:

  • Raspberry Pi 2 Model B, which is arm/v7 too
  • OS Raspbian GNU/Linux 11 (bullseye)
  • Docker version 20.10.5+dfsg1, build 55c4c88 (got it with apt install docker.io)
  • command I used to start the container: docker run -it --rm -p 6901:6901 dmotte/desktainer

In my case everything works fine.

The problem you are facing is pretty strange and requires further investigation, but I'm unable to replicate your issue, so I'm afraid I cannot help :(

Have you tried it on a "normal" host (not qnap)? Does it work in that case? Maybe this could be kernel-related or maybe qnap just doesn't provide full Docker support, who knows

Yes the problem is only on qnap ts231P2... if you can do some tests on armhf you would make many of us qnap owners happy

Docker on qnap is Limited but ubuntunovnc run correctly with supervisor

Hey @SiNaPsEr0x, I updated both the desktainer and desktainer-rootless images to Debian 12 "bookworm". This means that Xvfb has been upgraded from version 2:1.20.11-1+deb11u6 to 2:21.1.7-3. Maybe something could have changed regarding qnap support. Would you please try again? Thanks a lot

Some QNAPs with armv7 was updated with page size 32K after that some containers that was created for page size 4K didnt work.
