Caffeine should prevent Ubuntu from falling into hibernation or suspend mode. It's not working for me so far, maybe I do some mistake:

I have opened Caffeine Indicator, activated it (cup has rising steam) and computer fall into hibernation after 30 minutes while terminal has active command or Firefox has active download. Some tech. details:

  • Lubuntu 14.04
  • Caffeine has version 2.8.3
  • caffeine process runs on background

Am I doing something incorrectly?

  • Thanks Jacob, you understand that my problem is not `Caffeine` behaviour but **system falling into hibernation while doing some job**. But, you know, now the lazy consumer speaks from me: I don't want to code in order to solve this "stupid-simple-basic" problem. This is what Canonical (developers) should do! I just want to click with mouse like "simple" Win user without using my brain :-) – Jasom Dotnet Dec 15 '15 at 17:44
  • First of all, I will try to find out if I use Caffeine properly, then I will search for another solutions... Caffeine (Kofeín) doesn't develop Canonical, but Ubuntu _falling into hibernation while doing a job_ does :-) I'm ex Win user who just fall in love with Ubuntu. It's not easy relationship but no Windows any more :-) – Jasom Dotnet Dec 15 '15 at 17:57
  • @DKBose, there is only link to [article](http://www.omgubuntu.co.uk/2014/05/stop-ubuntu-sleeping-caffeine) about Caffeine I have already read: _Caffeine is now fully automatic: when the active window is full screen, Caffeine inhibits desktop idleness (and thereby disables the screen saver and/or screen sleep)..._ What is considered to be a "fullscreen" activity? When I surf Firefox in `maximized` window or when I surf in Firefox through `F11`? In both cases machine fall into hibernation. – Jasom Dotnet Dec 16 '15 at 15:39

You can try Keep.Awake instead of Caffeine https://launchpad.net/keep.awake

I haven't developed a GUI for it yet so you will need to use the command prompt.

I still haven't gotten around to creating a snap or deb for it. However temporarily you can download the program from Launchpad here

The current version is stable and works on all Ubuntu versions from 14.04 up to 16.04. That said I am continually improving it and will be adding new features.

It works like a proper command. Type --help to see a full listing of what can be done. The examples underneath are only a few:

./keepawake.py --help

To run interactively:

./keepawake.py

To run as a background service:

nohup ./keepawake.py -r > /dev/null 2>&1 &

To run as background service and set 15 min (900 sec) as the user activity idle time before it determines that the user is idle:

nohup ./keepawake.py -u 900 -r > /dev/null 2>&1 &

To run as background service and set minimum CPU load as 13%:

nohup ./keepawake.py -c 13 -r > /dev/null 2>&1 &

To run as background service and set minimum network traffic as 5KB (5120 bytes):

nohup ./keepawake.py -s 5120 -r > /dev/null 2>&1 &

To run all three settings above (network, CPU, User idle) in the one go: 

nohup ./keepawake.py -s 5120 -c 13 -u 900 -r > /dev/null 2>&1 &
