When I run a mpirun comand in my Ubuntu 20.04 LTS I get the error Invalid MIT-MAGIC-COOKIE-1 key

I tried different procedures found in the forums and I also reinstalled my invidia drivers. Nothing worked. The problem is in the local system, I'm not using ssh connections and I do not have a .Xauthority file.

For example if I run: /usr/bin/mpirun -n 1 echo "HelloWorld"

I get: Invalid MIT-MAGIC-COOKIE-1 keyHelloWorld

This is annoying because when I want to redirect the output on a file I have this message in every row of a mpi comand.

How can I solve this? Thanks, Nabla

I installed Ubuntu 20.04 LTS and I'm experiencing several problems with the zoom.- For example:

• In firefox, if I press ctrl the page zoom in.
• When I open an image and I hover over the image with the mouse (without pressing any button) the image zoom out
• When I hover a gnuplot graph with the mouse (without pressing any button) the plot zoom out
• If I open a CAD geometrical model it zoom out when pressing ctrl. What can I do to solve this problem? Thanks, Nabla
