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 ). – Knud Larsen Dec 07 '21 at 12:05
  • "Tricks" to find files, 1. locate nouveau ........ 2. https://packages.ubuntu.com/search?mode=filename&suite=bionic§ion=all&arch=amd64&keywords=nouveau_dri.so&searchon=contents ...... (Version __ libgl1-mesa-dri (21.0.3-0ubuntu0.3) ). – Knud Larsen Dec 07 '21 at 12:11
  • 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? – Estatistics Dec 08 '21 at 21:00
  • When you install the OS, Ubuntu 21.04, nouveau drivers are set by default. Unless you choose "Install 3rd party drivers". – Knud Larsen Dec 09 '21 at 09:50

I think this could be what you want to look for:

sudo dpkg -l *nouveau*

the one with ii in front is the installed one.
