[Simh] Can't start VAX from SSH
I am working from home and can only SSH in to my desktop Mac at work. Our unhelpful IT department automatically patches and reboots our system, which must have happened last night. That terminated the SIMH VAX I left running. Normally, I leave my desktop logged in. Until today, I have had no trouble starting my SIMH VAX remotely. Today, no one is logged in to my desktop. When I SSH remotely and try to start my SIMH VAX, it fails immediately with the error message: $ ./vax-20200419 _RegisterApplication(), FAILED TO establish the default connection to the WindowServer, _CGSDefaultConnection() is NULL. SDL Video subsystem can't initialize Is there any way around this short of driving to work and logging in to my desktop?

Re: [Simh] Can't start VAX from SSH
In your ssh session, I would think you could disable the QVSS device in your VAX simulator configuration file and it would run VMS just fine. If that doesn't work (or if you never actually had the QVSS device enabled ), you could uninstall whatever libsdl2-dev package you've got on your Mac and then rebuild the VAX simulator and then run the rebuilt simulator.

Re: [Simh] Can't start VAX from SSH
Not sure if this will be helpful or not.. The SDL video subsystem error makes me think that they put in a patch that your current version of LibSDL has a problem with, or have applied some protection to prevent LibSDL from attaching to the Mac graphics console. You might want to check to see if there is a newer and more compatible version of LibSDL for your patched system version. Or obviously, turn off the VAX QVSS/QDSS component that requires the LibSDL library and start the VAX without the graphics head. :-( David From: Simh On Behalf Of Baker, Lawrence M Sent: Thursday, May 28, 2020 4:48 PM To: simh@trailing-edge.com Subject: EXT :[Simh] Can't start VAX from SSH I am working from home and can only SSH in to my desktop Mac at work.
