📄 Description

When you run the VNC version blob/master/vnc-version/Dockerfile and you stop/restart the container as:

docker stop <container ID>
docker start <container ID>

Then it fails with:

gtk initialization failed

This happens when when qemu tries to start. The problem is that the vncserver command in OpenCore-Boot_custom.sh fails with (but does not terminate the bash script) with the following error:

Warning: f21471f8a08f:99 is taken because of /tmp/.X99-lock
Remove this file if there is no X server f21471f8a08f:99
A VNC server is already running as :99

Adding vncserver -kill :99 || true before vncserver fixes the issue.
