Steam client detects GPU as Mesa llvmpipe instead of discrete Nvidia driver

This is from Steam's system info:

Video Card:
    Driver:  Mesa llvmpipe (LLVM 15.0.6, 256 bits)
    Driver Version:  4.5 (Compatibility Profile) Mesa 23.1.0-devel (git-e2c67ed 2023-03-02 jammy-oibaf-ppa)
    OpenGL Version: 4.5
    Desktop Color Depth: 24 bits per pixel
    Monitor Refresh Rate: 59 Hz
    VendorID:  0x10de
    DeviceID:  0x1e87
    Revision Not Detected

llvmpipe is a CPU software renderer for if no GPU is detected

Interestingly, steam report does detect it

lspci: error while loading shared libraries: libpci.so.3: cannot open shared object file: No such file or directory
os_release: 
    name:               "Ubuntu"
    version:            "22.10 (Kinetic Kudu)"
snap_info: 
    steam_revision:     124
    snapd_revision:     x15
lspci: 
glxinfo: 
    gpu:                NVIDIA GeForce RTX 2080/PCIe/SSE2
    gpu_version:        4.6.0 NVIDIA 525.78.01
lscpu: 
    model_name:         AMD Ryzen 9 5900X 12-Core Processor
xdg_current_desktop:    KDE
desktop_session:        plasma

It seems likely that the lspci issue is the culprit. Did we somehow remove that by accident?

pciutils is on line 266 of the snapcraft.yaml

I'm wondering if maybe it's also in gaming-graphics-core22 and the cleanup phase is somehow nuking it? Don't want to do work on the weekend so I'll leave this sit, I was just gonna play a game and got very confused.

You know this, but for the sake of posterity: this should be temporarily resolved by running sudo /usr/lib/snapd/snap-discard-ns steam, and should be permanently fixed by this snapd PR: canonical/snapd#12541

Worth trying this again with updated snapd and steam @ZoopOTheGoop.

[ZoopOTheGoop]

it works on edge/zygmunt's branch that good enough @ashuntu?

[ZoopOTheGoop]

tbh I think a workaround from simon fixed this ages ago

Probably, it's been a while. If it works fine feel free to close.
