Description Søren Sandmann Pedersen 2006-10-02 12:42:42 UTC 
See https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=1971651

Apparently luit can hang if the child runs before the parent gets around to
setting up the terminal. The patch I'll attach fixes this by make the child wait
on a pipe until the parent is done.

The hang is in tcsetattr() which seems dubious to me, so there may be an
underlying reason that should be investigated.

The patch attached to this bug 8490 cannot possibly get in; it's too ugly for
words.  The patch in bug 2443 looks okay to me.

Could anyone who can reproduce this please check whether the patch in bug 2443,
available from

  http://bugs.xfree86.org/attachment.cgi?id=1301

fixes this issue?

Thanks,

Juliusz

I just got hit by the bug (on Gentoo system with luit-1.0.1 and Xorg-7.1) and it
seems from quick testing that patch given does fix the bug, or at least I'm
unable to reproduce it so far.
