[mythtv-users] Intel Graphics No Signal when TV Turned On Over HDMI

In that thread it mentioned adding the following to
/etc/mythtv/session-settings

killall xsettingsd

That seems to resolve the issue.  It looks like this is an issue only with
xfce.  I am wondering if it would remain if I switch the window manager to
one of the other variants.  Just a thought.
