While I’m fine with Linux most of the time, the few times I got frustrated with Linux was when I was following instructions and getting different results because either information was wrong or there were steps that weren’t included. A few examples I can think of are:
There are a lot of games that I’ve played (mainly from Itch) that offer a Linux version, but that version isn’t tested and often times has mismatched libraries. In one case, they forgot to bundle the Linux version with the game’s assets and only included the executable.
A lot of Linux installation guides just tell you that you can just install the distro from it’s LiveCD. Maybe this is the case for some computers but every computer that I’ve installed Linux onto required some extra steps. I’ve always had to disable secure boot and then re-enable it after installing but I’ve never seen a guide mention that, just some random answers on askubuntu that suggested it. They also never mention that you should use the LiveCD to make sure that everything is working properly.
There are some emulators that I’ve never gotten the Linux versions of to work properly and I can only get the Windows versions to work properly. PCem keeps telling me it can’t find any bios even though I put them into the specified folder. Mesen (the pre-Mesen2 version) runs but I can’t change any of the settings and the only documentation that exists is for the Windows version.
