MWorks always uses main display

This comment was split from the discussion: voltage from port DAC0

Selection of either the Main Display or Display 2 results in the display on the Main Display (the one with the macOS Dock).

When these preferences are toggled, they are updated in the user-level file (0 for Main, 1 for Display 2), but the display used does not change, and nor does the system-level file.

   Hi Lindsey,

   (I split this in to its own discussion.)

   Since it sounds like the preferences mechanism is working correctly, we need to start considering other possible causes. Some questions:

   1. Are you seeing this issue on multiple Mac's or just one?
      
   2. Have you made any recent changes to the system(s) where you've observed this problem? Did you, for example
      
      • install a new version of MWorks?
      • upgrade to a newer version of macOS?
      • replace or reconnect either of the displays?

   Thanks,
   Chris

   Hi Chris,
   This issue was just on a single Mac.
   It followed an upgrade from High Sierra to Catalina. We did not install a
   new version of Mworks (though we later tried reinstalling to see if it
   would help- it didn't) or replace/reconnect the displays (I'm not sure if
   this was ever tried).

   OK, that's useful info. What version of MWorks are you using on that machine?

   MWorks was 0.10 (a nightly). Same as on the other computers.

   Hi Lindsey,

   I created a little command-line utility that prints out some info about all the connected displays. I'm hoping it will shed some light on what's happening here.

   You can download the tool from Dropbox. After unzipping it, run it from Terminal. For example, here's what happens when I run it on my iMac:

   $ ./screeninfo
   Screen 0:
       Name: Built-in Retina Display
       Direct Display ID: 1
       Frame: {{0, 0}, {1920, 1080}}
       Vendor number: 0x610
       Model number: 0xA04C
       Serial number: 0xFD626D62
       Is main display? Yes
       Is active? Yes
       Is in mirror set? No
   Screen 1:
       Name: LED Cinema Display
       Direct Display ID: 2
       Frame: {{-1920, -120}, {1920, 1200}}
       Vendor number: 0x610
       Model number: 0x9236
       Serial number: 0x274680D
       Is main display? No
       Is active? Yes
       Is in mirror set? No
   

   Can you run this on your problematic machine and send me the output?

   Thanks,
   Chris

   Also- I can't test the other issue with dac_cycle until we solve this one because it's the same computer...

   Hi Lindsey,

   Here's the output:

   Thanks. Unfortunately, that all looks perfectly reasonable, so it doesn't really help us.

   Also- I can't test the other issue with dac_cycle until we solve this one because it's the same computer...

   I don't understand. dac_cycle just runs in Terminal. How does the display issue affect it?

   However, it's interesting that the same machine is exhibiting both of these weird issues. Is this a Mac mini? Is it using an external GPU?

   If you don't mind, could you run the following command in Terminal on that machine and send me the output?

   /usr/sbin/system_profiler -detailLevel mini SPHardwareDataType SPDisplaysDataType SPUSBDataType
   

   Thanks,
   Chris

   Sorry- I was wrong about not being able to test things on this Mac- I can. And dac_cycle.mwel still doesn't work.

   Also- yes- this is a mac mini (late 2012) running 10.15.7.
   There is no external GPU.

    Hi Lindsey,

    Now I'm wondering if all this weirdness is due to a mismatch between the version of MWorks I built your plugin against and the version you're running. It's really never safe to use a compiled MWorks plugin with any version of MWorks other than the one you compiled it against, but usually the failure modes are obvious (e.g. MWServer crashes), so I hadn't been thinking about it.

    To test this theory, can you try installing the latest MWorks nightly build on this machine? Please do not install any version of your U6 plugin (or any other non-standard plugins). Then, try loading and running the RSVP demo experiment, which is located at

    /Library/Application Support/MWorks/Examples/RSVPDemo/RSVPDemo.mwel
    

    If stimuli are still displayed on the main display, regardless of which display you select in MWServer's preferences, then we can rule out this theory at least.

    Thanks,
    Chris

    Hi Chris,
    I installed the nightly and ran RSVPDemo, but the display is still on Display 1.
    But this wasn't surprising since the display is fine on a bunch of other computers with the "unmatched" version of MWorks.
    Lindsey.
