I have a problem when running a certain program. The execution works perfectly fine, but there is an additional line that appears before the execution : Invalid MIT-MAGIC-COOKIE-1 key
Is there a way to prevent this message to appear ?
With some research, I tried different commands :
xhost +local: before running
Change the variable DISPLAY with the export command
Check if the XAUTHORITY environment exists (it does not)
Do you have any other suggestions that I can try ?
Thank you in advance.
This indicates a permission Problem or simply a wrong magic cookie ..
what works for me:
xhost + 192.168.1.2 for virtual boxes , then in the virtual machine :
DISPLAY=192.168.1.1:0.0 dbus-run my-x11-program
the MIT-MAGIC-COOKIE is stored in the file .Xauthority of the user who is running the desktop
you might have an already wrong-filled .Xauthority ?
you could also just "steal" this one (transfer via ssh) or copy on
localhost , sometimes
sudo works , and
when everything fails: run via ssh with e.g
ssh -YXC myuser@the-machine "the-command"
if you encounter failures concerning
MPI_init() from openMPI, you should read the mpirun-gui section from the manual there is another thread in the SE community describing what MPI_Init() it does
