Machine fails to come back from suspend when running as a virtual machine

[Will Cooke]

This is a bit of a compound issue:

1) It is possible to suspend a machine via the top-right menu in GNOME Shell. Click and hold on the power button, it will change to a pause icon. Click this and the machine will suspend. You then can't get the machine to resume.

2) Not being able to resume could be a kernel bug, or a virtualbox bug, or none of these.

3) With a recent change upsteam https://gitlab.gnome.org/GNOME/gnome-settings-daemon/commit/2fdb48fa auto-suspending might be a default because of energy star requirements. If this setting is standard, then anyone running a virtual machine might find that they can't resume that machine because it's gone to sleep automatically.

I tried duplicating #3 but all I got was a notification

"Automatic Suspend
Computer will suspend very soon because of inactivity."

But it doesn't actually auto-suspend. So maybe it's a bit annoying to have that notification but not a critical bug. If you think that's a worthwhile bug, please file that bug separately.

For #1, to resume from suspend, click in the VirtualBox menu: Machine > ACPI Shutdown.

While not very intuitive, it vaguely makes sense that pressing the virtual power button would be a way to resume a computer from suspend if mouse or keyboard input doesn't work and there is no lid to open.

So I'm going to reassign this bug to VirtualBox.

I think this is invalid then. The method to resume works.

I agree about it being invalid, pressing a key or something else, should not poweron the machine again, we have ACPI menu just to emulate such hardware keys, thanks for enlightening me about the change in gnome-settings-daemon, I got it as a weird default change, even if I wasn't aware of the rationale behind it!
