I'm pretty new to Linux, nevertheless I built a server from an old computer and I'm currently running ownCloud, Minecraft and a Webpage on it. I would like to reduce the power consumption to a minimum.
First of all:
Monitoring: I tried to get PowerTop to show me actual Wattage Comsumption to define who is the most demanding part there.
powertop --calibrate does not give me that information.
So I'm guessing that the Graphics card (Geforce 210) is using pretty much a lot of the power. Powertop also says, that the 210 is "used" for 100%. I'm using the default nouveau-driver. And I'm starting ubuntu in text-mode (GRUB_TERMINAL=console //text base grub menu)
The server is only used in SSH, no Monitor, nor a Keyboard attached.
- Q6600, slightly undervolted.
- Asus Geforce EN210
- Seagate 7200.12 HDD
- 1 Gigabit Ethernet card.
Total Power Comsumption @idle: 68 Watt
Any hints that i could follow to reduce more power consumption? Any hints to have proper monitoring? Can i switch off the Graphics card at all?
Thanks in advance!
