I have been using NoMachine for a long time at NERSC. Recently, seemed to have messed up my configuration, or something. I honestly don’t remember anymore exactly what happened. Anyway, I have installed NoMachine, downloaded the configuration file from NERSC, deleted the .nx directory, and even tried deleting some files in ~/Library/Preferences, but have not been able to get back to the (default) way that it was. Unfortunately, I do not backup my applications and so can not go back to my old version of NoMachine. I have gone back to old version of the NX5 Configuration .nxs file.
The problem is that I get blank window, whereas I used to have a bar that bottom of the window with (4) virtual desktops and my minimized xterms, etc. Now when I minimize a xterm I can not get it back. If I move an xterm to another desktop it is also gone forever. This bar also had a launcher that would open an xterm of some of the machines at NERSC, like Edison, Cori, etc. I can right click and get an xterm and then ssh to the NERSC machines, so I am alive, but I would like to get back to where I was before.
