Comment 5 for bug 1821652

// PLEASE NOTE: this an next comment are re-do's of this, as my right-screen rototated during this
// PLEASE NOTE: next comment is a retry of only some of the steps in this

I booted the live thumb drive (19.04 daily described above; it hasn't been re-written).

Verified that my display.change wasn't suddenly working now (nope, no change & clicking 'apply' caused it to grey-out etc... I took a screenshot (attached), then opened term & entered command copied from request in last (prior) comment

The command caused lots of lines to print, then paused....
I waited, then suspected the debug screen was waiting for me to do something, so I opened DISPLAY.settings

The [display.settings] window appeared to be locked (as if apply had been clicked; had I not closed it?? so I closed window)
I re-opened [display.settings] window & it seemed again to not respond, noticed a few more lines appear in debug.term.window, then noted (change of color to my right) that my right screen had rotated as I wanted!????

I'll save this locally, and then reboot & re-do this steps adding notes
