[solved] stops after 'Adding udev rule'

I got it working on Elementary OS: Freya
Here are the steps I took.

1. Update the distribution.
2. run:
sudo ./displaylink-driver-xxxxx.run --keep --noexec
3. edit the install script to have DLM upstart job run outside the if statement
(step 3 was necessary as neither if statement would trigger for me.)

Best of luck!

HTML Code:

echo "Adding udev rule for DisplayLink DL-3xxx/5xxx devices"

  add_udev_rule

  echo "Starting DLM upstart job - OUTSIDE IF STATEMENT @CUSTOM EDIT"

  add_upstart_script

  add_pm_script "upstart"

  start displaylink

  if [ "upstart" == "$SYSTEMINITDAEMON" ]; then

    echo "Starting DLM upstart job"

    add_upstart_script

    add_pm_script "upstart"

    start displaylink

  elif [ "systemd" == "$SYSTEMINITDAEMON" ]; then

    echo "Starting DLM systemd service"

    add_systemd_service

    add_pm_script "systemd"

    systemctl start displaylink.service

  fi

However, doing the fancy chmod +x on the shell script and running it, does nothing. Executing the original .run appears to execute the original (unfixed) file, and I can't execute a folder.

Please, tell me what you did. :S

hey,

it's been a while so I'm grainy on the details but if I'm remembering correctly, all I did was take the

Code:

    echo "Starting DLM upstart job"

    add_upstart_script

    add_pm_script "upstart"

    start displaylink

outside of the if statement (cut and paste before the if statement). So, it no longer checks "upstart" == "$SYSTEMINITDAEMON".

Try that and if it doesn't work, let me know what error message you get.
I'll try to debug it with you on my machine.

you have to run the script with the option "install", i.e. do

Driver Corrupted

I don't have any code with respect to the 'upstart'. The script turns into a mess at line 500. I downloaded diff versions and using diff computers. still a corrupted generated script. Does anyone have any suggestions or the original?

Code:

....

if test "$keep" = n; then

    cd $TMPROOT

    /bin/rm -rf $tmpdir

fi

eval $finish; exit $res

It's not corrupted, it's a self-extracting shell "archive" with installer logic created with makeself.

You can

Code:

export SYSTEMINITDAEMON=upstart

before you run the installer, then you wouldn't have to modify the script at all I think.

you say all this like its obvious, but...

for someone who only knows Python and saying I even know that is a stretch, this doesn't help at all. for one, my install.sh script doesnt have the part of that if statement that you all are talking about pulling outside the loop that I've been able to find using sudo pico to open the file.
additionally, what do you mean with this comment about the "export SYSTEMINITDAEMON=upstart" before running the installer and avoid the need to alter the script at all? regardless of where I've cd'd into on my computer, I can't for the life of me get anything but an error using that code snippet, if used alone or in conjunction with running any of the .sh files in an attempt to install.
Could you please be more specific? I just need to get my second monitor working so I can actually be effective in my research, and I haven't been able to since ubuntu updated frOm 18.04.1 to 18.04.2.
