 The NVIDIA driver is software that allows the operating system to communicate with the NVIDIA graphics card in order to control the GPU, manage performance, handle displays, and run graphics smoothly. This enables the computer to properly use the GPU for things like fast graphics, gaming, video editing, and hardware-accelerated apps.

-**Server**
+### Server
 
 Headless/compute‑oriented driver that does not include the Xorg display driver and related graphics stack, keeping only the kernel module and CUDA libraries. Used where no graphical output is neded.
 
 ```bash
 sudo apt install nvidia-driver-[version]-server
 ```
 
-**Headless**
+### Headless
 
 No display driver included, but contains the kernel module and user‑space libraries (CUDA, OpenGL/Vulkan). It’s meant for machines that run GPU workloads without ever attaching a monitor.
 
 ```bash
 sudo apt install nvidia-headless-[version]
 ```
 
-**Headless-no-dkms**
+### Headless-no-dkms
 
 Same as `‑headless`, but the kernel module is **pre‑built** for the current kernel instead of being compiled via DKMS. This eliminates the need for a compiler and DKMS infrastructure, which is handy on minimal container images or very locked‑down systems.
