Comment 49 for bug 41994

I found what may lead to a solution: using vbetool instead of xset seems to ignore input.
instead of running
xset dpms force off,
using
sudo vbetool dpms off
will turn off the display and not turn on unless I close the lid(invoking the default screen blanker) and then move the mouse, press a button or something else.

I don't have time right now to make a replacement lid.sh, but I'll post one asap(if I can somehow call sudo without a password prompt... oh yeah, i can mod whatever sudo file to allow vbetool), and later maybe look at the source code in order to get a real fix.
