Linux is the kernel. A full operating system is in the different distributions. Since I'm guessing you're new to the whole Linux thing, here are my beginner recommendations
It all matters too what you want to do with your computer...
Meh, Firefox has always been under the radar in terms of the general public for a long time. Partially because of Chrome and Google's marketing, partially because with using a different browser engine, I think that does alienate some people. Most of the popular browsers out there besides Firefox...
Agreed. There are quite a few packs and themes that are straight up patchworks of other themes or simply do not work.
Ehh, not quite. I'm not looking for an icon pack or theme that is supposed to copy MacOS or Windows, more like have that 2000s application theming that was 3d and looked glassy...
Oh, I have heard of AND used Gnome-Looks before. But I'm asking if anyone knows of an icon or theme pack specifically out there. I've searched up and down GL for my needs and the closest pack I've found is the Obsidian icon pack which even then doesn't live up to that sorta 3d, glassy look I want.
I'm looking for some good 3d icon and system themes, especially for GNOME if possible. When I mean 3d, I mean in the sort of stuff like old school MacOS interface system icons or WIndows Vista. Things that have some depth, shadows and and colorful.
Ok, but there are a ton of Linux applications out there, especially on the PC Linux.
Is the issue that you can't run applications you've used on other OSes (MacOS or Windows), there are already a plethora of equal or arguably superior applications.
