to start the Xvnc, i tried both a simple:
Xvnc -br -deferglyphs 16 -nolisten tcp :1 -ac &
and also:
Xvnc -br -deferglyphs 16 -nolisten tcp :1 -ac +extension XVideo &
and even:
Xvnc -br -deferglyphs 16 -nolisten tcp :1 -ac +extension BIG-REQUESTS
+extension DPMS +extension Extended-Visual-Information +extension GLX

+extension XInputExtension +extension XKEYBOARD +extension XTEST
+extension XVideo &
(These are all the extensions that are supposedly available)
