DisplayLink Forum - DisplayLink 1.4 (defaults can now autologin)

The Jamf Pro "files and folders" payload isn't intended to launch applications. That would likely create a significant security risk. :)

Apple recommends using a Launch Agent. With that said, the one that comes with the DisplayLinkLoginScreenExtension.pkg package doesn't seem to work.

Code:

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0">

<dict>

        <key>CFBundleVersion</key>

        <string>1.4.0 (120)</string>

        <key>Disabled</key>

        <false/>

        <key>KeepAlive</key>

        <true/>

        <key>Label</key>

        <string>com.displaylink.DisplayLinkUserAgent</string>

        <key>LimitLoadToSessionType</key>

        <string>LoginWindow</string>

        <key>ProcessType</key>

        <string>Interactive</string>

        <key>ProgramArguments</key>

        <array>

                <string>/usr/bin/open</string>

                <string>-W</string>

                <string>/Applications/DisplayLink Manager.app</string>

        </array>

        <key>RunAtLoad</key>

        <true/>

        <key>ThrottleInterval</key>

        <integer>5</integer>

        <key>Umask</key>

        <integer>0</integer>

</dict>

</plist>

It's a moot point now, since 1.4 provides a method that uses the defaults command. It's a huge improvement that allows the use of a Configuration Profile using Applications & Settings payload, using Jamf Pro.

1. Launch Terminal and run this to create a preference file:

defaults write /private/tmp/com.displaylink.DisplayLinkUserAgent AppAutostart 1

Then run this to convert the preference file to an uploadeable format:

plutil -convert xml1 /private/tmp/com.displaylink.DisplayLinkUserAgent.plist

Then cat the file to make sure it is readable, if it comes back with gibberish, it wasn't converted properly:

cat /private/tmp/com.displaylink.DisplayLinkUserAgent.plist

2. Create a new Configuration Profile using the "Application & Custom Settings" payload, and upload /private/tmp/com.displaylink.DisplayLinkUserAgent.plist to the payload, using com.displaylink.DisplayLinkUserAgent as the preference domain, scoped to all computers.

3. There is no step 3. :)
