Yosemite Monitors - Out of Order After Reboot?
-
I'm a little late to this discussion as well, but @mark, has Apple given any word of this issue? Has it been fixed in El Capitan? I'm still on Yosemite, but from the research I've found, it seems the problem goes all the way back to Mountain Lion and is a known bug at Apple. This issue also seems to affect screen sharing. I'm running off of a 2008 Mac Pro, but the booth in this theatre is in an awkward position, so I do mapping via screen sharing on my MBP in the house. I can connect to the Mac Pro and I can see the screen and mouse, but when I try to click on something, it ends up clicking on a completely different screen. Now this might be a totally unrelated issue, but it seems like screen sharing isn't recognizing the arrangement either. I'll try Mark's fix, and see what happens...

Dear @knowtheater,
I don't know that Apple has publicly acknowledged the problem, nor have I specifically filed a bug report about it.As far as the clicking and ending up on a different screen entirely, this one I've not heard of. (And I assume here you're talking only about use via Screen Sharing, is that right?)But do try my fix above and see if that helps at all. Then report back.Best Wishes,Mark -
Well, things were looking good for a few days, but all screens out of order again for the show Sunday. Not a big deal, re-ordered in Izzy preferences, although in the re-ordering, it seemed to somehow loose it's mapping. Nothing within system preferences was changed, only the stages within Isadora preferences were changed. All three projectors are running at the same aspect ratio (btw, they are three different brands and models of projector, if that makes any difference). I've attached photos of what the projection should look like vs what it looked like when the projectors lost their assignments.
And yes, @mark, the clicking problems were solely in trying to use screen sharing. I ended up using Chrome Remote Desktop, which recognized each display and I could control the desktop, but it was super annoying, as it has a built in time limit, which I prompts a click to confirm that I'm still sharing. I wasn't able to bypass it or even control that click via remote, so every 15 minutes I had to run back into the booth to confirm. It worked, but I got a work out as well...For what it's worth, [HERE](https://discussions.apple.com/thread/4157760?start=0&tstart=0) is a pretty lengthy forum about the multi display issue.

I assume that you followed my procedure above? Are you saying the problem happened again anyway? (Remember, it only works if you never change the display order in the Displays System Preference Pane after following the five steps above. If you modify the layout at all, it will not work.)I ask only because at least a half-dozen users got back to me reporting success with the method I described above.Best Wishes,Mark -
Yep, followed the procedure you outlined, but then all of the projectors reverted to 800x600. I changed the resolutions, but not the display order, rebooted, and everything was out of order again. So, I went through the procedure again, and haven't even opened up the preference pane since. It was fine for a few days, but has since been out of order again. Not that big of a deal, as I've walked the stage manager through reassigning the stages in Isadora preferences, it's just weird...

Yeah, well, this problem is really a hassle, especially for anyone who wants to create an installation that doesn't require daily maintenance. I wish Apple would just fix it already!
I actually wrote some code that can identify the make/model of the display/projector, so Isadora might be able to figure this stuff out itself. But unfortunately it doesn't help if all the displays/projectors are of the same make and model. (There is actually a serial number field associated with the device, but no device I tested actually implemented that feature.)Good Luck!MP.S. If you need to share screens, use Apple's built in screen sharing if possible. Totally seamless and easy.
