Curious, there's no such line in my profile (also default).
Do you have base-files-1.1-1 installed?
That comes with /etc/profile.default that has that line in it,
and hence my /etc/profile too

Try commenting out the export HOSTNAME line in /etc/profile and see if
the problem disappears.
That did solve the problem and LyX started successfully.
So now we know which 'tr' is hanging, can we find out why is it so?
It does not hang when I open just a bash window, and the HOSTNAME var
is set correctly.
FWIW, I've bumped into situations where something worked ok in DOS but
not Cygwin, or vice versa. It turns out that permissions for the same
file may be different (or at least appear different) between DOS/Windoze
and Cygwin. (This only applies to Win 2K and XP, and maybe NT.) I'm
wondering if maybe lyxwin32, running under DOS rather than Cygwin, tries
to invoke some other program for which it lacks, or appears to lack,
I've tried this with or without CYGWIN=ntsec, no difference.
I'm cc'ing this to the cygwin list also, maybe somebody can shed
some new light on this.
