Title: Screen on dim, will not "undim" 

This was a mistake I introduced with my former fix to idle behaviour correction. After a number of days running this I noticed the issue. This corrects the bug, and as a precaution, I have run this patch for a number of days to ensure that it does not affect other system components (Unlike last time)
