will installing nvidia-utils break nouveau and mesa?

i want vulkan support for nouveau just for very simple 2D games, but with my previous experience with nvidia drivers i don't wanna risk installing it, i had to do a reinstall twice
i have quadro FX 880M
and i tried installing nvidia-340xx
didn't go well

so is installing nvidia-utils along side nouveau and mesa alright?

No.
340xx doesn't support libglvnd, so you'll link the nvidia GL libraries (that are incompatible w/ mesa GL)
The nvidia*-utils package will also blacklist the nouveau kernel module, so in case the nvidia module fails for whatever reason, you'll be left w/o a drm kernel module.

That being said, several threads in the past couple of days have successfully installed the 340xx drivers and if anything goes wrong, you can still boot the multi-user.target (2nd link below), in doubt along "nomodeset", for a console login.
Alternatively you can boot a live distro and fix the system from there.

Finally: Do NOT use the nvidia installer from nvidia.com - it provides the exact same driver, minus the required patches and will make a mess out of your /usr/lib that you cannot easily undo.

i did successfully install nvidia drivers once but they were extremly broken and barely functional, icons not loading screen very buggy.
but is there anyway to add vulkan support to nouveau?

nVidia makes good hardware. Where they differ from AMD however is that AMD has long provided documentation about their hardware which means that today AMD hardware is well supported for open-source drivers. nVidia has long not provided documentation, meaning Nouveau is largely the result of trial-and-error and has taken far longer than it should have to even get where it is. And Vulkan support in Nouveau is nowhere near AMD and Mesa as a result. Recently providing documentation is changing with nVidia, but much remains to be seen about how they operate in that regard going forward.

Intel with their new hardware is providing code and documentation, they're new to the premium graphics card space but they're starting off open.

In your future choices, someday you will buy a new graphics card, keep in mind the above about AMD, nVidia, and Intel.

DId you confirm "glxinfo -B" that you were running on the nvidia blob and not somehow the vesa driver?

However, I'm sorry to say, but that's a Tesla chip and it won't support vulkan w/ any driver on any platform (neither does Fermi)
