OK, I looked at the article and am very disappointed because although relatively well written (compared to some other arch wiki ones), this is advanced stuff and lot of things are not clear for me so I can really mess my system. I just don't have enough knowledge of experience to digest such amount of information and use the correctly. In fact, I don't want to. I am not a technical user (still a rare thing in linux word) and I just want to use system, not mess with its basics to turn on some basic option. I know that sometimes that's not possible but at some point some basic things should be just there and don't require user to have linux master degree to add them.
I am torn, because I do like TLP (I used it in the past on ubuntu and it worked WONDERS for battery) so I'm not inclined to replace it with old pm-utils. On other hand pm-utlis did what I wanted but are said to be depreciated and not developed. What is the alternative then? It seems that TLP doesn't offer that kind of functionality and other packages that do, overlap with TLP so that's a potential can of worms.
Like I said, wiki article is just too much and I am confused. Systemd have just basic options but doesn't provide what I want, namely GRAPHICAL SWITCH IN PLASMA MENU FOR SUSPEND/HIBERNATION.
Does it mean that with pm-utils gone there is a whole and there is no user friendly solution to fill it?
