Problema

Bad video card drivers!
-----------------------

Minecraft was unable to start because it failed to find an accelerated OpenGL mode.
This can usually be fixed by updating the video card drivers.

Ah Ja
Tiene razón camal3on.
Actualiza tu controladora grafica…[/b]

Actualiza tu tarjeta grafica desde su pagina official como:
AMD Graphics Drivers & Software <------ Tarjeta grafica AMD/ATI (es lo mismo xD)
Descarga de controladores NVIDIA <------ Tarjeta grafica Nvidia
https://downloadcenter.intel.com/default.aspx <------- Tarjeta Grafica Intel
si no es ninguno de esos busca en google.

Tambien puedeser que no tengas los requisitos minimos, si es asi comprate una tarjeta grafica no son muy caras

Se te ve entendido de tarJetas gráficas…

Arreglado xDD

Tal vez tus drivers están desactualizados
