    I am experiencing a problem when attempting to open a graphical window when starting Amrvis on LBL’s Cori System. When attempting to run the program in a standard terminal window using ssh -XY, the program works fine. There is only a problem when I attempt to start the problem through NX. The error message I receive is:

    X Error of failed request: BadMatch (invalid parameter attributes)

    Major opcode of failed request: 1 (X_CreateWindow)

    Serial number of failed request: 140

    Current serial number in output stream: 166

    Amrvis is a data visualization program available through Git at “” that requires the AMReX code base to build and run (available at the same address).

    Local client: Mac client Version 5.3.9

    Server version: 5.2.21 Linux

    Let me know what other information you require.

    Thank you for your help!
