X processes do not always start properly after resume

[Mary Gardiner]

About 80% of suspend/resumes on this machine (a Fujitsu Lifebook S6120 for what it's worth) work fine. However, the rest of the time upon resuming I successfully put my password into gnome-screensaveer and while I can use existing programs opened prior to the suspend, I cannot start new programs.

According to strace, it's blocking on a socket read, here's the relevant output when I try and open an xterm:

connect(4, {sa_family=AF_FILE, path="/tmp/.ICE-unix/15504"}, 22) = 0
fcntl64(4, F_SETFD, FD_CLOEXEC) = 0
write(4, "\0\1\0\0\0\0\0\0", 8) = 8
read(4,

There appears to be no way to reset the state of this satisfactorily, other than completely logging out of and logging back into X.

Actually, at least one application will launch: xpdf. Ones that do not include xterm, xclock, tomboy, epiphany.
