In that case, the way I would handle things would be to just disable
99video if our kernel drivers are smart enough in a separate hook --
something alongthe lines of:
#!/bin/sh
. "${PM_FUNCTIONS}"
smart_kernel_video()
{
# If we are using an ATI or nVidia binary driver, do nothing.
[ -d /sys/module/nvidia -o -d /sys/module/fglrx ] && return 0;
local kernel_rev="$(uname -r |awk -F '[_-]' '{print $1}')"
# Intel can to the same thing, but only at or after kernel 2.6.26.
# FIXME: a more accurate way of testing this?
[ -d /sys/module/i915 ] && \
[ "$kernel_rev" >= "2.6.26" ] && return 0;
return 1
}
case $1 in
suspend|hibernate) smart_kernel_video && disablehook 99video ;;
*) exit 0 ;;
esac
