Sorry, if I execute mpirun in a *really *bare terminal, without X
Server running it works! but with an error message :

sudo gdb -batch -ex "thread apply all bt" -p $(ps -C mpirun -o pid= |

Maybe that will give some insight where mpirun is hanging.

Hello Gus,
Thank you for your answer.. Unfortunately my problem is much more
basic. I didn't try to run the program in both computers , but just
to run something in one compu
, etc.

Hello,
I installed kubuntu20.4.1 with openmpi 4.0.3-0ubuntu in two different
computers in the standard way. Compiling with mpif90 works, but mpirun
hangs with no output in both systems. Even mpirun command without
parameters hangs and only twice ctrl-C typing can end the sleeping
program.
