Hi Calvin,

Sorry - I should have provided more specific links.

The missing file for the 4.2.0->4.2.1 patch isn't a problem - 4.2.1 patches
some doc files which aren't included in the src-1 tarball, but in the second
tarball.  The second tarball isn't needed to build the server, so I didn't
suggest you download it.

The only instance we've ever seen of vnc.so causing hangs when loaded into
the console X server was with a RedHat 7.3 test system with a particular
model of graphics card for which the console X server's drivers were rather
ropey.  The current vnc.so has to grab the pixel data *back* from the
graphics card, which is obviously not as well supported/tested as the more
common task of putting pixels onto the graphics card.  Our card did also
display some weird behaviours even without vnc.so installed, though, so we
couldn't be sure that that was the cause.

One other thing to remember is that if you replace vnc.so while you have a
console X server running, you must remember to move or rm the old one before
copying the new one into place, otherwise you overwrite the library binary
while it's still in use, which will either fail the copy, or cause the X
server to hang.

If the vnc.so module causes you too many problems then, once a user is
logged on to the console X server, you can run the x0vncserver program
instead of using the module.  This shouldn't really be any more stable, but
it's worth a try.

Regards,

Wez @ RealVNC Ltd.
