 In summary, Second Try to install VPixx 3DPixx was doomed by having copied the wrong file to ''/usr/share/X11/xorg.conf.d/xorg.conf''.

 VPixx (Lindsey Fraser from technical support responding on behalf of Sophie Kenny) replied to me within an hour!  Based on the detailed email instructions, I did both of these things:
-. Changed line 62 of DatapixxImagingStereoDemo.m

 This made it so that the LCD glasses at least started flickering.  They were badly out of phase or frequency, so that there was no stereopsis at all, however.
-. Deleted ''/usr/share/VPixx Software Tools/'' directory and installed latest version of VPixx software tools from their website ([[https://docs.vpixx.com/download/|https://docs.vpixx.com/download/]]).

 This installed everything to ''/usr/local/share/VPixx Software Tools''.

 Ironically, perhaps, there are now some extra flashes and flickers that seem to happen when the background of the display changes, although fortunately not when the letter stimuli appear.
+I tried uncommenting-out (turning on) this line:
+<code matlab>
+   Datapixx('SetVideoStereoVesaPhase',0); % Added 2024-02-28 by adc to try getting rid of drifting horizontal band
+</code>
+Result: band moves around now = worse than before.  Will comment the line out again.
