Re: [fuse-devel] fusexmp and xterm

[Jamie G. <gu...@bl...>]

Inside the chroot, try running with strace and see if xterm can 
connect to your local server,

  $ strace /usr/bin/xterm 2> log2

  $ grep /tmp log2
  connect(3, {sa_family=AF_FILE, path="/tmp/.X11-unix/X0"}, 19) = 0
  connect(4, {sa_family=AF_FILE, path="/tmp/.ICE-unix/7675"}, 21) = 0

Also look for .Xauthority access, like someone else said,

  $ grep home log2
  access("/home/guinan/.Xauthority", R_OK) = 0
  open("/home/guinan/.Xauthority", O_RDONLY) = 4
