However can't seem to get any for the "Display blanking modes" to work -- screen stays on all the time. Has anyone else encountered this problem?
Old script - the display blanking mode options do not include the recently added CHDK
set_lcd_display( ) function.
Recently being 2013-10-2
Of the three available functions, only the first (
BKlite ) is going to work with recent cameras. The other two use functionality that Canon dropped maybe 10 years ago.
Sorry.
BKlite should work for you but IIRC it takes a little time before it kicks in.
