I just installed Ubuntu Desktop 16.04 on a little notebook (acer aspire). I will use it as a little linux server. As my screen is dead, I needed to plug an external display with VGA. Everything works fine, but, when I remove the cable, the computer instantaneously go to sleep.

I tried to add (as suggested here How do I disable my system from going to sleep?) the following, but didn't succeed:

sudo vi /etc/default/acpi-support # and then set SUSPEND_METHODS="none"
sudo /etc/init.d/acpid restart

Any suggestion?

Thanks,

This is due to the screen failure, because the pc thinks the lid has been closed! To solve this problem, edit this file:

 /etc/systemd/logind.conf

Uncomment the line: HandleLidSwitch=suspend and replace suspend with ignore like this: HandleLidSwitch=ignore, finally restart your system.

I hope this can help you!
