SIMH VAX exits immediately without reading the configuration file. That's the part I hope can be fixed. If the SIMH VAX was built with SDL support, but the configuration file is for a VAX without a graphics head, then I should think the SDL failure should be irrelevant. If the configuration file does try to connect to a graphics head, then that is when the SDL failure should matter, causing the configuration to fail.
It looks like I will have to rebuild the current SIMH VAX without SDL support for SDL failures to be ignored.

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.

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? Larry Baker US Geological Survey 650-329-5608 ba...@usgs.gov
