ubuntu installation on dedicated servers will auto-suspend

[fvigotti]

Hi, your ubuntu installation script almost work ok.. one major issues has been that the server will automatically suspend after about 20 minutes of activity.. ( and a hetzner robot power button is required to take it back online )

after investigating the issue i've fixed with this :

sudo apt-get remove xserver-xorg-core

thanks for your work btw :) it's well done

just deployed an ubuntu 20 and I cannot see a xserver-xorg-core installed. will see if the server suspends.

the root cause should be the power manager by desktop environment, For gnome, you can disable it:

Settings->Gnome Power Saving Options：
1.  Screen Blank > Never
2.  Automatic Suspend => Off

you remove xserver-xorg-core, so you remove gnome too:)
