[Message part 1 (text/plain, inline)]

Hi Everyone,

I'm using Guix 1.1 x86_64 in a virtual box VM. I've noticed when the
guest enters "power suspend" state I cannot wake it. The guest stops
responding over SSH and stops accepting UI input. I have to cycle
power to bring it back to life.

Power settings are:

  * Blank Screen - 15 minutes
  * Automatic suspend - Off

I don't see other relevant power settings in the Gnome app.

Jeff

I don’t know what the emulator is doing, but I do know that this works
well on the bare metal.  :-)

Do you have similar issues with other distros/OSes hanging about suspend
in that emulator?

Thanks,
Ludo’.

I had no other problems until today.

Today, I installed Ubuntu 20.04 in a VM for testing. It is exhibiting
similar problems. In the Ubuntu case, it is not hanging. Instead, the
screen goes black and I cannot get it back; but I can still SSH into
the Ubuntu machine.

I guess it's another Gnome bug that will be abandoned in 6 months.

OK.  I’m not sure there’s much we can do on our side—it sounds like an
interaction issue between VirtualBox and the kernel’s power management.
I would close the bug until/unless we have evidence that this is a
Guix-specific issue.

WDYT?
