# Fixes HD Flash and HTML5 video becoming extremely choppy after a suspend/hibernate.
# Despite the comment below about Nvidia, I experienced this problem on an ATI card.
# Has side-effects related to virtualisation (see above post for details).

# Original comment:
# Disable hyper-threading processor cores on suspend and hibernate, re-enable them
# on resume. Presumably helps for buggy nvidia behaviour.
# This file goes into /etc/pm/sleep.d/
