The first thing I done before I installed Linux OS is find out the tools to get logs or common troubleshooting commands in case I get stuck and on my own. I found the Endeavour OS logs guide before I made an account on the forums back then, along with finding guides (some of them Listed below) and made notes myself.
Maybe other newbies (As this post is in the newbie area) may find these threads interesting like I did although these are not log grabbing threads as that has already been listed.
Users can still post here for help obviously and not trying to force the RTFM mentality, this is just personally how I done things when I was new and of course this is a lot of information if someone has an issue right now to be fixed and may confuse some others if they are new but I could never write answers to questions in as much detail as others did in these posts.
So maybe these are useful things for newbies to read in free time to prepare for long term Linux use and avoiding potential issues or future frustrations as Arch linux and based distros are a bit more hands-on than some other distros (Or Windows and MacOS) since Arch is originally DIY in design and a lot of new users are unaware of this. The new users who don’t mind a bit of reading (As new users are very varied in knowledge and all sorts of skill backgrounds) likely don’t know these threads exist either.
