I can confirm it here on my systems: both my desktop and laptop suffer this problem after a hiberate to disk/suspend to ram plus resume cycle (both dapper). On my systems this does not happen on a regular basis: about 1 in 4 resumes have this problem. But I cannot determine what causes the problem. The programs 'hang' on the ICE-unix file, as seen with stracing gcalctool.
See also this bug, which seems to be the same bug: https://launchpad.net/distros/ubuntu/+bug/56140. Only the solution of using DISPLAY=:0 does not work for me. -- Can't start programs after resume from suspend/hibernate https://launchpad.net/bugs/52200 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
