Hi

Yes root does not help because the search path is not including
/usr/sbin for vnc.
/usr/sbin and /sbin is only intended for system commands that root run
for system maintenance and for system services.
This is why I do not understand why xrdb has moved its location. The
intention of this tool is for the user to run.

In your case you can edit your startup file manually to include the
path directly.

Best regards

// Ola
