Games : Minecraft Error: org.lwjgl.LWJGLException: Pixel format not accelerated? [duplicate]

This question already has an answer here:

• Is there a list of error codes for Minecraft? 2 answers

It doesn't make it beyond a launch, before it reports to me that its crashed and gives me this file report. I'm not savvy with this stuff, so I literally have no idea how to fix this. Can someone help me get back on minecraft?

PS. My file report is as follows :
