Please set an environment variable SYSTEMINITDAEMON - MX Linux 19.2

[unnome]

Hellos! I can't seem to be able to proceed with the installation as I am requested to set an environment variable.

The symptoms are very similar to issue 445

Installing driver version: 5.3.1

DisplayLink Linux Software 5.3.1.34 install script called: install
ERROR: the installer script is unable to find out how to start DisplayLinkManager service automatically on your system.
Please set an environment variable SYSTEMINITDAEMON to 'upstart', 'systemd' or 'runit' before running the installation script to force one of the options.
Installation terminated.

This is my debug output

$ sudo ./displaylink-debian.sh --debug

• Setting the variable doesn't seem to help. I tried all 3 suggested values, to no avail.
• Exporting the variable doesn't seem to help. I tried all 3 suggested values, to no avail.

Any help would be appreciated :)

Thanks!

How are you running debian?

[unnome]

Thanks for your reply! I'm using Debian in a MX Linux 19.2

$ lsb_release -d
Description:    Debian GNU/Linux 10 (buster)

Apparently systemd is disabled by default on your distro.You should enable it and then retry the installation: https://mxlinux.org/wiki/system/systemd/#enablingsystemd

thank you! I tried running with systemd however the boot failed, complaining that it "failed to start Load AppArmor". I will note that the error log had several mentions of that failure message.

I then installed AppArmor, however am not yet able to run debian with systemd. The only visible effect is that the "failed to start Load AppArmor" appears only once in the error log.

I know that my comment is not very useful, but I'm eager to follow your instructions

[Barabazs]

Sorry, I can't help you with that. You'll have to search on your distribution website or forum.

It makes sense. Thanks Barabazs. I'll close this ticket and open a new one if restarting with systemd enable doesn't solve the issue.
