How does the power efficiency of DSLR compare to Ubuntu? Would I get longer battery life?

  I somehow doubt it. Sure, there's a lot less stuff running, so there are fewer wakeups. But on the other hand, it's missing some essential power-saving software like `acpid` that tells bits of hardware to take a rest in the first place.

      acpid being only one of the tools usually there to interface with power management, I'm not really up-to-date what Ubuntu uses nowadays. And yes, as with a lot of hardware stuff you're going to end up in the kernel in the end, but without any management/supervision software (never mind drivers), you usually won't get a quiet and cool laptop. Try starting a barebones arch installation on one these days, without acpid, tlp etc.…

    Perhaps the project should aim to either integrate acpid or if deemed to heavy, write a lighter version of it.
