Comment 4 for bug 909337

Hi nicolas, your workaround script works for me, but it takes about 60seconds to resume, even with the sleep 45 removed.

I changed it to this:

#!/bin/sh

echo ON > /sys/kernel/debug/vgaswitcheroo/switch
sleep 2
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch

exit 0

Now I get 9.8watts usage vs. 18-21ish watts and double battery life.
Works awesome like this, thanks for showing us the workaround :D
