 Does anyone have vnc (loaded as .so by the Xserver) working at the moment?
 
 I just tried it from packages and I got this backtrace out of the
 coredump it gave me:
 
 .... lots of unexciting loading stuff ....

 My guess would be that VNC has the wrong idea of an XEvent Structure
 but I'm not able to look into it much more (I'm running this setup on
 a rather cramped box with only flash storage). Does this work if built
 from ports yet, I just pkg_add -r'd it all down here.
 
 I wasn't bitten by the missing font-alias package due to it being
 supplied by something else, but that problem is still there also
 I think.
 [ ports/118293: net/vnc Xvnc won't run without fonts.alias installed ]
 
 Anyone else trying to get this fixed ?
