CentOS - Mar 2014 - Full Screen in Dual Monitor setup.

This question is related to Centos 6.4 running on workstations with dual
monitors attached using Nvidia drivers, twinview mode.


We've gotten stuck on a window manager specific issue with getting
'vncviewer' (tigervnc) to go full screen to both monitors.

If Gnome is the window manager, we have no issues.  Hitting "F8" in
vncviewer and selecting "full screen" expands the viewer across both
displays as expected.

If KDE is the window manager, vncviewer will only expand to completely fill
one of the two displays, even if the 'vncviewr' option "enable
full-screen
over all monitors" is enabled.

In the "Multiple Monitors" system settings all options are enabled,
suggesting that multiple monitor full screen mode should be working.

Any thoughts on how to get full screen to work across both displays
properly on KDE?

I apologize for the repeated question.   I have not been getting copies of
my own messages posted to this list, so I didn't realize they were getting
posted until I checked the archive.  (I've checked the mailman settings,
and I'm supposed to be getting copies of my own message, so it's not
that).
