display arrangement changes after sleep
Hello,
The issue is that the arrangement and orientation of external displays may get changed upon waking from sleep. Along with that, the position of the windows may change on those displays as well.
After looking for other posts on the problem, I see that this seems to be a common issue across different types of Mac that has existed for quite a few years. Despite that, there does not seem to be a good solution. I had it on my Macbook Pro, but it did not happen every time it woke from sleep, so it was a nuisance, but I could live with it so I never solved it. Now with a new iMac, I have two displays with rotated orientation, which means they are unusable until I go reorient and rearrange them. The problem is also happening more frequently.
A couple clues:
- Rebooting the machine sometimes results in the correct orientation and arrangement coming back.
- Unplugging the monitors and reconnecting them sometimes brings back the correct orientation and arrangement. This is the work around I have been using.
- Turning them off and back on does not seem to help.
Conclusion: The settings are not lost; they are just not being loaded and applied.
Questions:
- For Apple developers: Is there something that can be changed in the wake process that will ensure that the display orientation and arrangement settings are loaded and applied? Please look into this and make a change in the next MacOS update.
- For a near term fix: I believe that the settings are stored in com.apple.windowserver.plist. Is there a way to get the windowserver to reload these settings and apply them? Does that make sense?
Thanks.
