How to find the nouveau version used or installed into linux system (ubuntu v21.04)?

I read a lot information eg. here. However, none of the info found presenting the version of xorg / nouveau drivers. For an unknown reason, information is presenting only nvidia drivers version and not that of nouveau drivers.

So, what is the proper way to see what version of nouveau drivers are used by system?

The "user space" nouveau driver(s) : `/usr/lib/x86_64-linux-gnu/dri/nouveau_dri.so` from the mesa package `libgl1-mesa-dri` https://packages.ubuntu.com/hirsute-updates/amd64/libgl1-mesa-dri/filelist .... ( and nouveau_vieux_dri.so ).

"Tricks" to find files, 1. `locate nouveau` ........ 2. https://packages.ubuntu.com/search?mode=filename&suite=bionic&section=all&arch=amd64&keywords=nouveau_dri.so&searchon=contents ...... (Version __ libgl1-mesa-dri (21.0.3-0ubuntu0.3) ).

I have installed nouveau drivers using sudo apt install but also from source. So, I dont know which of two system use. Locate presents which results? nouveau drivers installled or used by system?

When you install the OS, Ubuntu 21.04, nouveau drivers are set by default. Unless you choose "Install 3rd party drivers".

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
