Not everything actually requires a GUI, obviously. But anything that requires configuration, especially for controlling a hardware device, should have a fully functional GUI. I know Linux is all about being in control, and users should not be afraid to use the command line, but if you have to learn another bespoke command syntax and the location and structure of the related configuration files just to get something basic to work then the developer has frankly half arsed it. Developers need to provide GUI's so that their software can be used by as many people as possible. GUI's use a common language that everyone understands (is something on or off, what numeric values are allowed, what do the options mean).
Every 12 to 18 months I make an effort to switch to Linux. Right now I'm using Archlinux, and it has been a successful trip so far, except my audio is screwed, I can't use my capture card at all, I had issues with my dual displays at the start, and the is no easy way to configure my AMD graphics card for over clocking or well anything basic at all.
I'm not looking for a windows clone, I love that I can choose different desktop environments and theme many of them to death. I even like the fact there are so many distros. Choice is a big part of linux, but there is clearly a desire to get more people moving away from Windows and until that path is 95% seamless most people just won't. Right now I think Linux is 75% to 85% seamless depending on the use case and distro but adding more GUI front ends would, imho, push that well into the 90% zone.
GUI is not a dirty word, it is what makes using a new OS possible for more people.
EDIT: Good conversation all. This is genuinely not intended to be a troll post, I just feel it is good to share experiences especially on the frustations that arise from move between OSes.
No you can GTFO if that is your attitude towards people volunteering their time to bring you an open OS and all the tools you need for free.
Yes, there is still a lot of room for improvement but attacking devs for not providing a GUI is not a good way to interact with the community. If you really want to see improvements then you need to help make those improvements with constructive discussions not hostile statements. We owe you nothing.
My title was intentionally flipant. But I thin the automatic assumption that command line is always fine for linux desktop needs to evolve. Not to say it hasn't, but there are definitely some basic gaps.
No, your title was rude and condescending. "Flippant" is a different thing.
Flippantly insulating the Linux devs is not the way to improve things. It has evolved and continues to do so. There are far more GUI tools for managing things then there has ever been. The only thing you have mentioned in your post is AMD GPU overclocking - not something I would consider a novice task nor something most people are going to want to do. So the priority to get a GUI to do this is quite low. Hell, it looks like there are no userland tools at all - only raw kernel interfaces. So it is really something we are lacking any tooling at all - let along GUI tools.
Better to advocate for these tools than insult devs for not having yet created them.
