Hi, I have a few questions and I'm seeking for some advice. The first one is related to the Powertop utility.
In my opinion it's not a bug or an issue, Powertop works fine but I was curious about something that I observed in Powertop.
If you look at the image you can observe that there are two processes for display backlight one is under 100% usage while the other one is 0% but both seem to have the same general power consumption. I'm running Arch Linux on a laptop (x86_64) with no other displays running, and what I'm interested in knowing is whether they refer to the same display process and if that is normal?
Also are there customized kernel offerings out there with focus on Power Management? What can be done other than using tlp, powertop, etc. to slash down on power consumption? I've gone over the various Arch wikis on power management, and have pretty much read everything there is and at the moment the main power hog for laptop is the display even with the lowest brightness setting.
On a side note the laptop I'm using (Samsung 370R4 - Series 3 model) doesn't really have a good battery life so I'm also thinking about getting a Chromebook and perhaps installing Arch Linux for some light coding and stuff. I use i3 window manager and can live in really minimal environments and rely on vim for coding so perhaps a Chromebook would be ideal for me.
Please advice if you would recommend a Chromebook and if so which model would you recommend.
Thanks.

Regarding the Chromebook, the C720 from Acer seems to have quite a Linux following. Ships with SeaBIOS so you don't even have to flash it yourself. Upgrade the SSD and it's a pretty capable machine, although coding on it might get annoying if you do a lot of compiling.
