This has been brought up on IRC before, and I believe the concensus was you 
can't rely on the current mode when starting the app because there's no way 
to tell if the current mode is the default or something another app set.

As far as XRandR is concerned, mode 0 is always the default, but the desktop 
manager can set a different mode per user on login. The way to fix this would 
be to get some way to query the desktop manager for the default mode, or to 
extend XRandR to be able to change and report different defaults. Neither of 
which is possible right now.
