I think the corrrect command line I have is:
Code:
x11vnc -q -display :0 -create -nocache 10
I will try as a next step to uninstall and reinstall x11vnc. I will try using a different distribution source and see if that helps. If that doesn't, and I am not sure what else to do, I will probably just downgrade my Mandriva Linux back to 2009.1, on which I believe close to that command line seemed to work, according to my notes.
