Fail to open DISPLAY as host.docker.internal:0 by xclock on Ubuntu / OrbStack

[zacky1972]

Hi,

I did the following steps:

1. brew install orbstack
2. brew install xquartz
3. open -a XQuartz
4. xhost + 127.0.0.1
5. git clone https://github.com/zacky1972/docker-ubuntu-xorg.git
6. cd docker-ubuntu-xorg
7. docker image build --rm --no-cache --pull -t zacky1972/ubuntu-xorg .
8. docker run -it --env="DISPLAY=host.docker.internal:0" --rm zacky1972/ubuntu-xorg xclock

Then, I got the following warning and error:

WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested
Error: Can't open display: host.docker.internal

The warning is OK, because my docker image on https://github.com/zacky1972/docker-ubuntu-xorg.git runs on x86_64 by Rosetta 2.

However, I can't fix the error. The documentation of OrbStack shows DISPLAY should be set to host.docker.internal:0. Help me!

This is related to XQuartz settings rather than OrbStack issue. Changed the XQuartz settings in "Security" tab as shown in the image:

Then restart the XQuartz and it should work.

Thank you!

The setting is checked, so after restarting XQuartz, it works fine.
