I just tried this with various shells on Solaris 8. It only happens when using
the Bourne shell (/bin/sh). csh, ksh (and a version of bash) are all fine,.
when run interactively. Using a non-interactive invocation of the shell ('ksh
- -c vncserver', for example) did not work.
Presumably, under the Bourne shell, Xvnc is left in the same process group as
the foreground process - and ^C sends the signal to the process group, not
just the foreground process.
Running as a background process in a shell script, as Steve Palocz suggests,
will work - unless vncserver wants input from the terminal (e.g. to set the
password the first time).
The following change to the vncserver perl script will fix it (note this may
not be the latest and greatest vncserver script, so you may have to tweak it
a bit):
