[petsc-users] error attaching debugger (again)

[Dominik Szczerba]

I again can not -start_in_debugger, here is the output:

mpiexec -n 2 Solver run.xml -start_in_debugger -display :0.0
[0]PETSC ERROR: PETSC: Attaching gdb to Solver of pid 16633 on display
:0.0 on machine tharsis
[1]PETSC ERROR: PETSC: Attaching gdb to Solver of pid 16634 on display
:0.0 on machine tharsis
xterm Xt error: Can't open display: :0.0
xterm Xt error: Can't open display: :0.0

I could always go along with the first two messages so far, xterms
would open. But now with no apparent reason or system change (other
than usual systematic system updates) the additional errors appear and
xterms do not open. This is Ubuntu 11.10 64 bit. Any ideas what to
check please? I saw the FAQ about ptrace, it solver my problem once
before, but now it does not seem to be the case.

Regards,
Dominik
