To be clear, the primary larger screen where the taskbar/app-launcher 
is pinned behaves as expected for emac's modeline context menu.  The

The x-toolkit is "lucid".  Here is the clip from the config.log in 
the build directory.

'''

The GTK values are not set in config.log

I don't have emacs configured for email and worry the mechanism might 
misfire.  Sorry about that.  I just discovered the config.log file is
1Mb long and decided not to include that in the attachment.

These are all the libraries associated with the emacs binary.  I want 
a skeleton thin build for my basic need but don't really know what to 
exclude.  Hope this helps.
