Thanks you for the report. Could you tell us the VM version: you can get it from the systemReport menu. By any chance could you check with Pharo 12 and the latest VM?

BTW I use it often in Pillar Here is the pharo (no ui) script I use. Now I'm on mac so may be there is a difference.

#!/usr/bin/env bash
# some magic to find out the real location of this script dealing with symlinks
DIR=`readlink "$0"` || DIR="$0";
DIR=`dirname "$DIR"`;
cd "$DIR"
DIR=`pwd`
cd - > /dev/null 
# disable parameter expansion to forward all arguments unprocessed to the VM
set -f
# run the VM and pass along all arguments as is
"$DIR"/"pharo-vm/Pharo.app/Contents/MacOS/Pharo" --headless "$@"

For Pharo 11 I downloaded VM and image from here https://files.pharo.org/get-files/110:

VM: https://files.pharo.org/get-files/110/pharo-vm-Linux-x86_64-stable.zip

Images tried: https://files.pharo.org/get-files/110/pharo64.zip and https://files.pharo.org/get-files/110/pharoImage-x86_64.zip

Unfortunately the pillar script gives me the same result, --headless option is not recognised.

I've tried Pharo 12 and that appears to have same issue, it's not recognising the --headless option even though if you run VM executable without an image it shows that as an option.

./pharo --headless /usr/local/pharo/pharo12/image/Pharo12.0-SNAPSHOT-64bit-4c71938.image

Usage: [] [--help] [--copyright] [--version] [--list] [ --no-quit ]

    --help       print this help message

    --copyright  print the copyrights

    --version    print the version for the image and the vm

    --list       list a description of all active command line handlers

    --no-quit    keep the image running without activating any other command line handler

    --deploymentPassword   if a password needs to be used by the user to launch the command

    --readWriteAccessMode, --readOnlyAccessMode, --writeOnlyAccessMode, --disabledAccessMode

                 specify disk access mode, read-write mode as default

    <subcommand> a valid subcommand in --list

    Preference File Modification:

    --preferences-file   load the preferences from the given <FILE>

    --no-default-preferences    do not load any preferences from the default locations

Documentation:

A PharoCommandLineHandler handles default command line arguments and options.

The PharoCommandLineHandler is activated before all other handlers.

It first checks if another handler is available. If so it will activate the found handler."

Hi,

Assuming i am looking at the current classes/methods in the Pharo 11 and Pharo 12 images the VirtualMachine headlessOption method returns: vm-display-null if the OS is unix . Trying --vm-display-null as an option doesn't work either.

Looking at the library directory for the Pharo VM version 10.3.0, it no longer contains library vm-display-null.so or any other vm-display-XXX objects, so presumably this is the reason why it doesn't work ?
Thanks

Non pharo solution, Pharo UI output sent to xvfb virtual session and run as a pharo user via systemd script:

Install Xvfb Create systemd script to run as a service:

Thanks for all such information.

I saw that you are on OS: RedHat 9 @tesonep may be you have a bit of time before holidays to investigate this issue?

This is strange, I'll check it during the week

Hi, I am encountering this problem in Pharo 12 as well. Specifically, when I run pharo under lldb and set the arguments as follows,

(lldb) settings set -- target.run-args "/Users/kumom/documents/Pharo/images/Pharo 12.0 - 64bit (stable)/Pharo 12.0 - 64bit (stable).image" --headless

the UI pops up after executing run.
