only one of three screens working after debian upgrade

So I have three monitors, all working fine under Debian stretch, but update to bullseye and now xfce only uses the one monitor.  I'm using the same 'etc/X11/xorg.conf' as before.  With that file deleted, xfce finds all three monitors, but two show identical displays (they are attached to the same card and the 3d monitor to a simple VGA card).  Before experimenting with deleting xorg.conf, the third monitor did work, but now it doesn't with xorg.conf reinstated. Again, all monitors are functional but not found correctly by xfce.  Solution?

BTW, the 'display' helper only shows the one monitor, so xfce isn't jiving with X properly.  It was a big update going to bullseye, I skipped right over 'Buster' (Debian 10) so problems are not unexpected.

Re: only one of three screens working after debian upgrade

Ok, got 'em working.  I had to kill xorg.conf and then turn of the 'mirror' thingy in the 'display' applet.  Why would the default be two monitors showing exactly the same thing?
