I forget to install NVIDIA driver

What!! The supported OpenGL shader language version is only 1.3? I was shocked when I am first seeing this.

I'm just feeling bored from my daily coding routine, thus thinking to try out something new to get some new inspiration. I grab the piece from learnopengl.com hoping to get some sparkling idea:

const GLchar* vertexShaderSource = "#version 330 core\n"
    "layout (location = 0) in vec3 position;\n"
    "void main()\n"
    "{\n"
    "gl_Position = vec4(position.x, position.y, position.z, 1.0);\n"
    "}\0";

int main(int argc, char **argv)
{
    ...

    GLuint vertexShader = glCreateShader(GL_VERTEX_SHADER);
    glShaderSource(vertexShader, 1, &vertexShaderSource, NULL);
    glCompileShader(vertexShader);
    // Check for compile time errors
    GLint success;
    GLchar infoLog[512];
    glGetShaderiv(vertexShader, GL_COMPILE_STATUS, &success);
    if (!success)
    {
        glGetShaderInfoLog(vertexShader, 512, NULL, infoLog);
        std::cout << "ERROR::SHADER::VERTEX::COMPILATION_FAILED\n" << infoLog << std::endl;
    }

    ...
}

But what's surprising me is that the program failed to run even though I have NVIDIA GT 610 installed. What even surprising me when I issue the following command:

kokhoe@KOKHOE:~$ lspci -vnn | grep -i VGA -A 12

Notice that the Kernel driver in use is showing nouveau?! That means I have not yet install the driver since the first day I got the NVIDIA card. To fix this error, I installed the driver (see here to see how I do the installation), make a final verification:

kokhoe@KOKHOE:~$ lspci -vnn | grep -i VGA -A 12

Ah ha~ now it shows nvidia is the current driver in use. Before I run the program, I just want to make sure the supported shader language is 3.3.

kokhoe@KOKHOE:~$ glxinfo | grep 'version'
server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
OpenGL core profile version string: 4.3.0 NVIDIA 352.63
OpenGL core profile shading language version string: 4.30 NVIDIA via Cg compiler
OpenGL version string: 4.5.0 NVIDIA 352.63
OpenGL shading language version string: 4.50 NVIDIA

Now my OpenGL info shows me version 4.5, it is far more advance than the expected version. This shouldn't be a problem with my program.
