I have a PC with Intel 4600 graphics and a fresh install of Xubuntu 13.10 64 bit. Any video playback causes the system to freeze up. The audio plays, but the video plays at about 1 frame per second, and the entire system become unresponsive. I am sometimes able to recover with xkill, but often have to switch to a text terminal and reboot.
However, youtube video does work. I even have played video inside a Windows XP virtual machine and it works fine. I've installed the restricted Ubuntu codec package, and VLC, but they have no effect.
It seems there are no Intel graphics for 13.10, and I can't find anyone else complaining of this. Any ideas?
EDIT: I got video to work in a Xubuntu 13.10 VM, and then natively by turning off hardware acceleration in VLC. The system is usable in this state, however, I'd rather not have to worry about any random program crashing the system if it attempts to use hardware acceleration.
Is there some way to turn off hardware acceleration globally?
