My first guess would be that you probably had a kernel update that broke your graphics drivers. There is a graphics kernel module that needs to be reinstalled whenever the kernel gets updated. If it doesn't get reinstalled for some reason the kernel upgrade will break your graphics. Try reinstalling your graphics drivers.
