steal the mouse back from SDL

I hate it when a poorly-behaved SDL app (usually mine) grabs the mouse, crashes, and doesn’t give the mouse back. Great, now I’m stuck in X with no mouse. Here’s a handy python script to get it back:

#!/usr/bin/env python
# get the mouse back after an SDL app crashes
import pygame
pygame.init()
pygame.mouse.set_visible(False)
pygame.event.set_grab(True)
pygame.quit()
