I wasn't aware of that limitation. Here's an older version of essentially the
same thing:

1: The Modesetting DDX is newer technology. It's good enough that AMD stopped
providing its fglrx driver for recent distro releases, and the Intel-specific
DDX went into maintenance mode (no major version upgrade) 7 years ago:
<https://cgit.freedesktop.org/xorg/driver/xf86-video-intel/>
2: AMD and Intel contribute to FOSS openly, while NVidia still does not.

Again, this was addressed by the inxi outputs I provided. Here one is again
with less editing, where nouveau is present only as the kernel driver/module
for the NVidia hardware device, while modesetting does X-specific duty:
# inxi -GISay
...
Graphics:
Device-1: NVIDIA GF119 [NVS 310] vendor: Hewlett-Packard driver: nouveau
v: kernel bus ID: 01:00.0 chip ID: 10de:107d
Display: x11 server: X.Org 1.20.10 driver: modesetting
unloaded: fbdev,vesa
...
Info:...Shell: Bash v: 5.1.0 running in: konsole inxi: 3.2.01
and for Intel (current devel inxi version for its improved presentation):
# pinxi -GIay
Graphics:
Device-1: Intel 4th Generation Core Processor Family Integrated Graphics
vendor: Micro-Star MSI driver: i915 v: kernel bus ID: 00:02.0 chip ID: 8086:041e
Display: server: X.Org 1.20.3 driver: loaded: modesetting
unloaded: fbdev,vesa alternate: intel display ID: :0 screens: 1
...
Info:...Shell: Bash v: 4.4.23 running in: konsole pinxi: 3.2.01-12
And for AMD:
# pinxi -GIay
Graphics:
Device-1: AMD Caicos [Radeon HD 6450/7450/8450 / R5 230 OEM] vendor: Dell
driver: radeon v: kernel bus ID: 01:00.0 chip ID: 1002:6779
Display: x11 server: X.Org 1.20.10 driver: loaded: modesetting
alternate: ati,fbdev,vesa display ID: :0 screens: 1
...
Info:...533 Shell: Bash v: 5.1.4 running in: konsole pinxi: 3.2.01-12
Thus, for most installations (non-ancient, non-bleeding edge), competent
X operation is possible without having any proprietary Xorg driver or
GPU-specific DDX installed. NVidia's own software is thus needed only
by those who need some specific feature only it provides.
