Or not. Do not confuse the nouveau kernel driver with the nouveau DDX (X and Wayland) driver. The nouveau kernel driver provides the kernel mode setting functionality that competent DDXes depend on. Xserver-xorg-video-nouveau is a reverse-engineered, *optional*, DDX built only for NVidia GPUs. The default DDX is newer technology, automatically used when: 1-it supports any non-ancient (AMD or Intel or NVidia) GPU; 2-KMS is not disabled; and 3-no optional DDX is installed. It can also be explicitly configured to be used even though an applicable optional DDX is available. It's provided by the xserver-org package itself. When in use, modeset(0) will normally be found copiously in Xorg.0.log. The modesetting DDX is in use here by all the NVidia GPUs I have that are new enough for it to support, those newer than approximately 10-12 years of age.
Old mainframe guys like myself probably shouldn't be giving GPU advice ;)
It worked perfectly with Stretch, nvidia non free and xserver-xorg, and with Buster, completely broken.
I tried, nvidia free and non-free, no result.
I cannot spend hours and hours to repair...
