Still no success. Here's a log file from fresh start to standby and resume:

FrontView+_20170208.log

Thanks for log.

It does seem a bit strange - the changescreen code runs with resume (on this log - and probably did before I added the resume hook with 1.205)

It selects Display2 as you have saved - but for some reason I presume doesn't change to display2.

What happens when you go the screen selection settings page - if you change display from 1 to 2 and save - does it appropriately move from one screen to another ?
