A PS4 can be jailbroken to run Linux. You can then install Steam and Halo and have Halo on Linux on PS4

The only issues I have with Nvidia is Wayland, which sucks because I actually really like Wayland.

AMD is generally better

Shouldn't do much if you only have 1 other desktop. For example I used Pop!_OS for years which comes with Gnome, but I MUCH prefer KDE Plasma so I had that installed the whole time and just never touched Gnome (it was still there, removing it would have broken stuff).

How is it compared to AppImageLauncher? That's what I've been using for a few things that only ship AppImage.

I think your best bet is Gameboy emulation for gaming, that GPU isn't gonna be doing any 3D stuff any time soon unfortunately

KDE Neon or Linux Mint will be your best betnfor a Windows-style layout. Just keep in mind it still isn't Windows so stuff will he different

YES! We really need to change the mindset of "Web3 = Blockchain/Crypto/NFT" to "Web3 = decentralized"

Pokémon Blue on a used Gameboy color when I was like 8. All downhill from there.

You may need to move away from Ubuntu to an Ubuntu-based distro. Pop!_OS still packages firefox as a deb

Pretty much any distro will do, but Ubuntu-based ones tend to be easier to use due to having menus and buttons for most everything. As for apps, here are my suggestions

~3D~

Blender

~DAW~

Ardour

LMMS

Bitwig

~VIDEO EDITING~

Davinci Resolve (if on Nvidia)

Kdenlive

Olive (alpha software, be wary of crashes and save often)

~IMAGES~

GIMP

Krita

Photopea (web app)

Inkscape

Lights may be possible with OpenRGB but I haven't personally messed with these kinda of software

Start with something designed around a graphical interface, pretty much anything based on Ubuntu will do this (Linux Mint, Zorin, Pop!_OS, etc).

If you use Nvidia Pop!_OS has an ISO file with Nvidia drivers already installed. It isn't hard to get Nvidia drivers on other distros but the more done for you the better.
