>I _just_ moved from Windows 11 to Kubuntu. None of that stuff is missing. In fact, unlike Windows 10/11, I didn't even have to install a graphics driver. My AMD 7700 XTX literally just worked right out of the box. Instantly. Ironically that’s not the case for Windows 10/11.
How did you install a driver on windows if your gpu didn't work out of the box?
No. That's not true. It does not do that. I've reinstalled Windows 11 several times to resolve issues or try these kinds of things out. It has never offered to download an AMD driver for me. This is false.
Windows 10 can 100% download and install an nVidia proprietary driver for hardware it finds.
Indeed I inadvertently trapped it in a boot loop by fitting 2 dissimilar nVidia Fire cards with different GPU generations. This works on Linux if you use Nouveau but not with nVidia drivers.
Win10 lacks an equivalent of nouveau. It booted, detected card #1, downloaded and installed a driver, rebooted, the card came up; then it detected card #2, which wasn't working, downloaded and installed a driver, and rebooted.
Now card #2 initialised but #1 didn't work. You can only have 1 nVidia driver installed at a time.
So, Windows downloads and installs the driver for card #1... reboots... #1 works, #2 doesn't... download driver, install, reboot...
The only way to interrupt this is to power off and remove one card.
When I replaced both cards with a single AMD card, it downloaded the driver and everything worked.
You are wrong. Source: my own personal direct experience.
Windows Update can and will grab most third-party drivers for your hardware if you let it, this includes video card drivers from Intel, Nvidia, and AMD.
