Been using Linux for almost three decades now. Just use Linux for what you need it for. Use Windows for what you need it for. Stop using either OS for the sake of using either OS. Gaming on Linux has come a hell of a long way in the last couple years. In a couple more years, the gaming landscape will be wildly different. You can always reassess at that time. If you have a couple games that are your number 1 must plays and they only work on Windows, then just use Windows. Trying to cobble together some janky mess, it’s just not worth it at all. Personally, I just played the games that played on Linux for a lot of years. It’s great what Proton has done for gaming on Linux. But if your games or your work are still on the fringe for Linux, no hard feelings. Just use what OS you need. That’s how this is all supposed to work. 30 years ago before Microsoft’s vendor lockin strategy. We bought pieces of software because we needed that software. Then we bought the OS that that software needed and bought the hardware that that OS worked on. Then you’d look and see what games were available to you and that was it. You should do the same. Linux is taking over anyways. Microsoft’s vendor lockin strategy is coming to an end if they don’t do something soon. In 3-4 years from now, you will see a lot of investment into the desktop side of Linux. You can always come back then.

Look up what makes a GUI. Something can be graphical but not GUI. Something that is GUI is obviously graphical. “All thumbs are fingers, but not all fingers are thumbs”.

It’s called a terminal emulator because it emulates graphically what used to output to a printer at the console of a mainframe. Then you got CRT monitors. The mainframes like the PDP-10 would output to a printer or CRT monitor. This was your terminal. A printer writes the output from the mainframe 1 character at a time, left to right, top to bottom. The CRT monitors were made to do the same. Obviously before outputting to a printer or CRT monitor, the output would show on a set of lights on the console. If you watched them change enough, you would know where you were in your program as it ran (obviously something only doable because the opcodes were not running in parallel through super scalar pipelines in the Ghz). With printers and monitors, you could increase the amount of feedback you get from the running or exiting program and give input to the system via a keyboard.

So, the terminal is not “technically” a GUI. We do use a GUI to emulate a terminal which receives the actual terminal output from the system and then displays it for you. They are not the same thing at all. GUI is a paradigm for what you display on a Monitor for the user to interact with. Modern monitors are fast enough that they can and do work well with the GUI paradigm. You definitely wouldn’t be sending GUI context to a printer.

So, if I switch the terminal output back to my dot matrix printer instead of my monitor, like back in the day, it’s not graphical right?

The only markets Linux doesn’t Dominate are the Desktop and console space. The only thing holding back Desktop domination is Microsoft and it’s vendor lock-in strategy. It says a lot when Microsoft has to use the power of their purse in order to maintain their position. Even Linux dominates in the IoT space with ~80% of the market, despite Microsoft having to make Windows IoT free.
