Ubuntu 18.04: Please don't enable automatic suspend!

[Michael]

As already reported on https://www.phoronix.com/scan.php?page=news_item&px=Ubuntu-18.04-Auto-Suspend, automatic suspend is enabled on desktop installations on 18.04. This is a very, very bad thing, because many installations are used as a server. Even on a desktop usage this is a very problematic setting (long downloads or calculations, demonstrations etc.) So, do NOT enable this without asking the user!

To make things worse, it seems to be both a user specific and a system wide setting.

But by far the biggest problem is that this shitty setting is even enabled during an upgrade from 16.04 to 18.04 - without any warning! I know, Ubuntu 18.04 is still in beta, but this is major problem which will cause big headaches to many users which use their system as a server. Luckily I have an IPMI as I have no physical access to this test machine...

It seems that this happens only to Unity/Gnome, not on mate desktops, but could be that this is caused by different desktop managers (gdm/lightdm).

Yes, this only affects desktops that uses GNOME settings (Ubuntu, GNOME, Unity, Budgie).

We will probably be changing the setting to only auto-suspend by default when on battery power. That addresses most people's concerns while still being useful to someone who accidentally left their laptop unplugged for a while.

This is being tracked in LP: #1759008 so I'm marking this bug a duplicate of that bug.
