Comment 1 for bug 1904153

Thanks for your report.

The page in question is part of the Ubuntu Desktop Guide, which primarily targets inexperienced users. So it's not the right place to elaborate and include technical details.

It's unfortunate that you experience problems with suspend. Please feel free to submit a bug report about that:

ubuntu-bug systemd

or add your observations via a comment on some of the already existing suspend related bugs:
