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?

Extra information:
