This is not true. From old Xorg logs:

[194415.365] (II) NOUVEAU driver Date:   Fri Apr 21 14:41:17 2017 -0400
[194415.365] (II) NOUVEAU driver for NVIDIA chipset families :

https://nouveau.freedesktop.org/DebianPackages.html recommends
xserver-xorg-video-nouveau.

However, it seems that a "modesetting" module is loaded by default:

[685925.554] (II) LoadModule: "modesetting"
[685925.554] (II) Loading /usr/lib/xorg/modules/drivers/modesetting_drv.so
[685925.554] (II) Module modesetting: vendor="X.Org Foundation"
[685925.554]    compiled for 1.18.1, module version = 1.18.1
[685925.554]    Module class: X.Org Video Driver
[685925.554]    ABI class: X.Org Video Driver, version 20.0
[...]
[685925.555] (II) modesetting: Driver for Modesetting Kernel Drivers: kms

This is from

  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=814902

(a different machine, but basically with the same config).

It seems that I haven't kept any Xorg log for the concerned machine.
