Problematic frame or Pixel format not accelerated
Meaning of error:
The Minecraft launcher won't start or Java tells you that you have bad video card drivers with the error message "Pixel format not accelerated".
The error message "Pixel format not accelerated", or problematic frame, is usually caused by having out of date or bad video card drivers.
While most of the time this error is caused by the video card drivers being out of date, it can also be caused by a gamepad device, or something being interpreted as a gamepad device (Headphones, controller, etc). If you believe this to be the case, please try disconnecting any other devices that you have connected to your computer, then restart Minecraft.
