Do you know what are these? These services are using around 40ms/s:

/bin/warm-daemon -auto -etc=/var/lib/warm-sched/etc -cache=/var/lib/warm-sched/cache

/usr/lib/xorg/Xorg -background none :0 -seat seat0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt1 -novtswitch

Xorg is the graphical engine. So you need it definitely.

Thank you! And what is the first one?

warmd manages "intelligent" caching.

if you want to play movies on your laptop probably you can create/recompile a hardware-accelerated version of VLC. At least I read something like this somewhere.
Also if you want to fine-tune that linux probably you need to compile/build your own kernel too.

so there's two gpus in there.
these laptops save battery by switching to the more resource-intensive (the amd) only when it is necessary, and run the onboard gpu otherwise.
under linux this does not always work so well.
you should check that out.

Hybrid graphics works fine for me. Not with bumblebee because it's for Nvidia cards only, but with "DRI_PRIME=1 programname" I can use GPU heavy apps with AMD GPU when I want to, but normally it's not in use.

Personally I don't like "powersave", and my general dislike for it and general like for "conservative" was confirmed when I read an article about performance and power saving abilities of the different CPU governors. Powersave was very poor at high performance, while by most vectors "conservative" was very good. This leads me to believe that "conservative" is a reasonable choice. It is in a way like powersaves, but it scales up better "ondemand" and saves power better than the "ondemand" governor.

This leads me to believe it could take longer to perform the same tasks using powersave rather than conservative, and per task have a higher power consumption with powersave than conservative. I am no expert, this is just my feeling about the issue. Conservative does not burst to max performance as quickly as "ondemand" either.

There is no real need to use the AMD in Linux is there? If he runs the Intel one? This should definetely save power, by using only the Intel one.

Unless ofcourse he plans do play games or render 3d stuff.

but return back to the original post, would like to know if windows was booted which gpu had been used/activated (and how was that video played at all).
