How do you install TTF files in Linux?

Two ways:

If you want those fonts to be globally visible to all users on the system, you, with root permissions, place them in /usr/share/fonts/truetype (may vary depending on your distribution). It may take X some time to notice the fonts there. If not, you can force refresh the cache with something like "fc-cache -fv".

Of course if this is a system where you are the only user, it's best just to shove them into ~/.fonts instead, as you won't need root permissions to do that. That and you might get the fonts discovered a bit quicker by simpy restarting the application you want to use the font in. If you want your entire desktop to use it, you might need to log out and back in.

By the way: There is no need to worry about whether "Windows" TTFs work in Linux, a TTF is a TTF is a TTF. They're not binaries, they have no architecture/platform dependency to their content, as all their content is is vector graphics and some other data.

What do you see when you first turn on a Linux system?

That depends on the hardware, the distribution, and what you are referring to by "first turn on." Most computers do not display anything at all for a brief period of time while the display is initialized. Depending on the system and how long it takes to initialize the hardware, you may also see a BIOS POST screen or a splash screen.

Then, depending on how the bootloader is configured, the system may either load directly into Linux, or present a menu for a choice of operating systems. There are several bootloaders that can boot Linux, with a variety of appearances.

Finally, when Linux itself begins loading, the appearance can vary tremendously, from a splash screen to a framebuffer console to a simple system console to no display at all.
