disabled screen can't be enabled again; missing from device tree #109

following up from https://news.ycombinator.com/item?id=34496697

I have tested the current head, and I have one remark.

It looks like disabling the screen works as advertised. It actually works better than expected, because the monitor goes into auto-select and picks the right input. But also, the display can't ever be enabled again, you must hotplug it for it to show up again. It goes entirely missing from System Information too.

CGSConfigureDisplayEnabled also seems to be missing from Apple documentation.

Having the same issue here. Documentation says that it disables monitor and removes it from OS list but would it be possible/preferable to disable but still retain the list so that it can be re-enabled. I'm not a C developer but from the code it would seem like when listing current profile you could never get enabled:false

I'm seeing the same behavior on my M2 laptop. I've updated the docs to reflect that some machines require unplugging/replugging to reenable.

In my case even "disconnect, wait 10 secs, reconnect" didn't help. Connecting to another usbc port solved. (mbp m2, macos 15.1)
