Nvidia on Ubuntu: Difference between revisions

Line 3:

I still do not have the Nvidia driver loaded - even after 40+ reboots and attempts. Instead I'm using the Nouveau driver but at least I have a working system and I believe now that I've finally figured out what needs to be done to disable Nouveau and install Nvidia - a project that I am approaching with greater scrutiny now. I'm documenting the things that I encounter in this journey.

Why not just continue to use [https://nouveau.freedesktop.org/index.html Nouveau], a project of the [https://www.freedesktop.org/wiki/ freedesktop] community? I mean "if it ain't broke, don't fix it" - right? In principle, I'd very much like to use nouveau. I'm not even sure that any alternative is "better" in any way - especially since ''I am not a gamer''<ref>I'm not opposed in any way, I just don't have the time to add another hobby. This is a clarifying statement for my use-case, and therefore, requirements.</ref>. My use case is to get the best performance from local LLMs.

== About this System ==

In your desktop environment, you can access 'System Settings' -> '[[About this System]]' to display basic info about your Software and Hardware environment including the 'graphics processor'. Mine says '''NV197''' - which is the codename given to the card by the Nouveau project<ref>https://nouveau.freedesktop.org/CodeNames.html</ref>. You can click on 'Show More Information' which reveals a multi-tab dialog for OpenCL, OpenGL, Vulkan, Window Manager and X-Server with extensive Graphics info.

In your desktop environment, you can access 'System Settings' -> '[[About this System]]' ([https://docs.kde.org/stable5/en/kinfocenter/kinfocenter/index.html KInfoCenter]) to display basic info about your Software and Hardware environment including the 'graphics processor'.

You can click on 'Show More Information' which reveals a multi-tab dialog for OpenCL, OpenGL, Vulkan, Window Manager and X-Server with extensive Graphics info.

Or, you can also get details from a variety of CLI commands like glxinfo, lspci etc.

Line 165:

On systems with Secure Boot enabled (mine), you most likely need to sign the module. See [https://download.nvidia.com/XFree86/Linux-x86_64/570.153.02/README/installdriver.html#modulesigning Signing NVIDIA Kernel Module]. However, I didn't get an explicit message that signing was a problem; and I did see that the installation process signs the module with a generated key. I assume that the MOK process hooks into the trust system somehow.

== Interesting Notes ==

Usually, when you have 'sudo' or root privileges you can do '''more'''. One exception is the X-Server. Root access to the server may be restricted. In that case,

<code>glxinfo</code>

will give

Error: unable to open display

A regular user will have no problem running <code>glxinfo</code>.

=== Different Desktop Environments ===

As a regular user, my DE is KDE Plasma (using Kubuntu) rather than the GNOME default of Ubuntu
