new X apps won't start after resume from hibernate

[John Leach]

This on Dapper on an IBM Thinkpad X40. Hibernate and resume usually work fine, but once in a while, on resume I can't start new X apps.

When starting them from the menu or panel,I just get an animated cursor for a while but it never starts.

All the apps that were running before hibernate seem to function fine (observed all the usual gnome panels and applets, and epiphany).

If I switch to a console and set DISPLAY=:0, I can start new apps fine. If I log out and back in, everything works fine too.

An strace of an app trying to run (gnome-terminal in this case) shows it getting stuck reading from /tmp/.ICE-unix/5045 which is connected to the program x-session-manager.

tail end of strace output follows.

socket(PF_FILE, SOCK_STREAM, 0) = 10
uname({sys="Linux", node="zazen", ...}) = 0
connect(10, {sa_family=AF_FILE, path="/tmp/.ICE-unix/5045"}, 21) = 0
fcntl64(10, F_SETFD, FD_CLOEXEC) = 0
write(10, "\0\1\0\0\0\0\0\0", 8) = 8
read(10,
