After the installation of Nvidia drivers fails, you won't have a functioning GPU, since you will no longer have the nouveau driver available either, and so the output of the same glxinfo command will show that "llvmpipe" is the renderer. | |||

LLVMpipe is a software rasterizer within the Mesa 3D graphics library that utilizes the LLVM compiler infrastructure to perform rendering entirely on the CPU. It acts as a software fallback when a dedicated GPU or its drivers are unavailable or malfunctioning, allowing OpenGL applications to run without hardware acceleration. Essentially, LLVMpipe takes over the rendering process when the GPU can't or shouldn't be used. | |||
