The hints are valid for any distribution. They usually rely on the kernel settings, not anything userland. So it doesn't really matter if you're looking at Arch, Ubuntu, or other guide. Even with specific services, the ideas usually hold between distributions - maybe you just need to correct a path or two.

File indexing services are things like locate, baloo, zeitgeist, etc. that try to save information about created files, so you can find them faster later on. On one hand side they give you faster results, but on the other they keep monitoring disk writes and impact your battery life.

So the file indexing services that you mentioned, often you have to go out of your way to install these, these would not be part of default file/folder management like pcmanfm?

I see Arch mentioned a lot. I used to be Linux Mint > Debian > tried Slackware > Ubuntu.... Slackware kind of sucked just because it was harder to setup/a lot of things didn't work like video playback. Not blaming it on them. Ubuntu I primarily switched to because they had drivers that Debian would sometimes not have like WiFi. Seems to make sense if more people use Ubuntu.

Anyway thanks.

Baloo comes by default with most KDE installations. Ubuntu used tracker (don't think it does anymore). So it's not that hard to find one of them running.

Thanks a lot for the information. Hopefully all of this will result in long battery life.
