The Linux Framebuffer Device (fbdev) is an older graphics interface in Linux, serving as a simple abstraction for a display framebuffer in memory. However, it offers limited functionality compared to DRM (Direct Rendering Manager).
In contrast, DRM provides a unified and consistent API for managing graphics devices, including support for multiple displays and GPUs. It allows for advanced display configuration, such as setting resolution, color depth, and other display modes.
