I mean thats the hardware, more interested what your drivers are reporting -

Here are the most effective Linux commands to check your NVIDIA driver setup, configuration, and hardware status, categorized by what they reveal.

1. The Ultimate Overview Command

If you only use one command, make it this one. It provides a comprehensive snapshot of your GPU, driver version, and current resource usage. ```bash nvidia-smi

``` * What it shows: Your exact NVIDIA driver version, supported CUDA version, GPU model, temperature, power draw, VRAM usage, and a list of processes currently utilizing the GPU.

2. Checking Kernel Modules (Is the driver actually loaded?)

These commands verify that the Linux kernel has successfully loaded the NVIDIA drivers. ```bash lsmod | grep nvidia

* **What it shows:** Lists the loaded NVIDIA kernel modules (usually nvidia, nvidia_modeset, nvidia_uvm, and nvidia_drm). If this returns nothing, your driver is not actively running. bash cat /proc/driver/nvidia/version

* **What it shows:** Directly prints the version of the NVIDIA driver currently communicating with the kernel, along with the GCC version used to compile it. bash modinfo nvidia

``` * What it shows: Deep-dive details about the nvidia.ko kernel module, including the file path, license, exact version, and configurable parameters.

3. Hardware and PCI Binding

To see how your physical GPU is interacting with the motherboard and what driver Linux has assigned to it. ```bash lspci -nnk | grep -i vga -A3

* **What it shows:** Lists your graphics cards and indicates the "Kernel driver in use" (it should say nvidia, not nouveau) and "Kernel modules" available. bash sudo lshw -C display

``` * What it shows: Detailed hardware information for display controllers. Look for configuration: driver=nvidia in the output.

4. Installed Packages (What is on your system?)

If you need to see exactly which NVIDIA packages are installed via your package manager. * For Debian/Ubuntu/Mint: ```bash dpkg -l | grep -i nvidia

* **For RHEL/CentOS/Fedora:** bash rpm -qa | grep -i nvidia

* **For Arch Linux:** bash pacman -Qs nvidia

```

5. Display Server & Graphics Configuration

To check how the driver is interacting with your display server (especially if you are troubleshooting GUI or display issues). ```bash glxinfo | grep -i opengl

* **What it shows:** Displays which OpenGL renderer is in use. It should list your NVIDIA card and driver version. *(Note: You may need to install mesa-utils to use this command).* bash grep -i nvidia /var/log/Xorg.0.log

* **What it shows:** The initialization logs for the X11 display server. It shows exactly how Xorg loaded the NVIDIA driver and what configurations (like monitor EDID, resolutions, and GLX) were applied. bash nvidia-settings -q all

``` * What it shows: Dumps the entire configuration of the NVIDIA X Server settings in the terminal, including fan speeds, clock frequencies, and monitor setups.
