Let us know if more build-time customizations would be useful.
If the system does not have the XTEST XTestGrabControl interface (some
early X11R5 systems have XTEST but not this interface), then configure
will automatically try to see if the DEC-XTRAP extension build
environment is available and use that for avoiding GrabServer
deadlock. If you want DEC-XTRAP compiled in no matter what, set
X11VNC_USE_XTRAP=1 in your environment. Note that DEC-XTRAP should
only be used as a last resort on legacy machines since the standard
XTEST works well. If there is interest for legacy machines to use
DEC-XTRAP for all of the user input injection (not just grab control)
let us know and we will put it in for you to try. (Note: DEC-XTRAP
grab control seems to be broken on Linux/XFree86)
