Display not awakening after Beta El Capitan 15A263e install

Wow - We're onto page 8! 😀

I wonder if the automatic reversion to graphics switching that you're seeing is symptomatic of the underlying graphics driver problem rather than being a secondary bug that's making it hard to troubleshoot. One way this could be occuring is if the graphics driver silently crashing is causing the graphics preferences to be reset.

Interesting thought. I wonder if that is something the Apple engineers could pick up in the sysdiagnose file with the bug report--sort of doubt it.

I may try disabling those drivers and see what happens. Hope I don't end up with a MBP of a different kind (MacBrickPro).

So long as you're careful with your Terminal commands, it's a low risk venture. Worst case scenario would be that you'd have to "Reinstall OS X" from Recovery Mode - this doesn't touch your user environment; just replaces all the system files from a fresh download of OS X.

Last night I disconnected the external monitor and let the MBP sit overnight with the lid open. No problems at all waking it up this am. And the Automatic Graphics Switching did not get rechecked.

I haven't done anything with the drivers yet.

That seems expected. I had it in my mind that we had established that an external monitor being connected was a necessary condition for the bug to be triggered. If you do decide to find the graphics bundle that contains the bug by renaming and trial and error, I can see it taking a while - If you start up your MBP with the monitor(s) connected and then run kextstat from Terminal, I may be able to narrow it down a bit for you.

Max,

Here's the kextstat output, monitor connected on startup. Please don't spend too much time on this.....

I do see one Geforce driver, line #125. Maybe that's it.

Hi Ken,

We don't have much longer on this forum - Apple are about to shut it down now that El Capitan is out of beta. But I think I may have found your issue. The (latest) likely candidate is an NVIDIA web driver I see you have installed (i.e. not native to OS X - one you downloaded at some point) called NVDAStartup.kext - it too has a google history of causing a failiure to wake when an external monitor is connected.

It's probably in your /Library/Extensions folder, but it might be in the System/Library/Extensions one too...

Best of luck if I don't hear from you again 🙂

Hi Max,

I found the file, 48kb, with an August 28, 2015 date, same as all the others with NV*.kext, although in the file contents the date is September 15, 2015. I don't recall ever installing any NVIDIA drivers myself. Strange.

Here are all those drivers. I wonder where they came from?

NVDAGF100Hal.kext

NVDAGK100Hal.kext

NVDANV50HalTesla.kext

NVDAResman.kext

NVDAResmanTesla.kext

NVDAStartup.kext

NVMeSMARTLib.plugin

NVSMU.kext

And here's some textfrom within the startup file itself:

Also, I tried to remove it in the Terminal using sudo rm -rf /System/Library/Extensions/NVDAStartup.kext, but it isn't permitted. I guess I'll have to do it in Recovery mode.

Sorry to lose you when they shut this forum down, sort of a matter of the parrot fleeing the coop in this case. I've enjoyed our dialogue. My email is kvatz at mindspring.com . Everyone else in the world already has my email, including the US national security agencies, which, as you know, monitor all of us.

I'll email you - but don't remove that kext yet - I'm wrong about that being the web version (there is one, but that isn't it). The reason I flagged it is that it seems the one that is loaded when you have external monitors added...

Thanks, Max. I waited until I heard from you, figuring that maybe it was an Apple kext.

One additional observation (to date):

While disconnecting the external monitor solves the wakeup problem, it also appears that keeping the MBP lid open may solve it, too.

That is, with long periods of inactivity, the external monitor connected, and the lid closed, the wakeup problem occurs maybe 50% of the time, even with automatic graphics switching off. But if I open the lid under the same scenario, the wakeup problem doesn't seem to be there (so far). Must have something to do with the computer not going into sleep mode when the lid is open, even though both screens are blank, that is, not the screen saver running.

Additional observation:

After two days, it's clear that leaving the lid open (and not having computer set to go to sleep automatically, rather only for the screens to go off), there is no fail to wake problem. And of course the computer stays awake with the lid left open, and is pretty warm to touch even after several hours of inactivity

So, what seems to be happening, although it doesn't help in terms of a global solution, is that by leaving the lid open, it's as if you're not leaving the computer at all, so there's no energy saving. Leaving the lid closed, with the external monitor connected, ends up putting the computer to sleep, or something like sleep, because it is cold to touch after several hours. And disconnecting the external monitor, w lid open or closed, also solves the wakeup problem, but of course isn't a convenient answer.

It seems to get back to the drivers, one way or the other, and so far, even with the Apple bug reports and the beta feedback reports, Apple either isn't aware of the problem, or else can't reproduce it and can't fix it.

No sooner did I write the above than the external monitor wouldn't display after letting the computer sit for 2 hours, with the configuration exactly as described above.

The MBP display was on, so I checked the graphics in system information, and both monitors were shown as using the discrete NVIDIA card and not the internal card. No amount of fooling around with the Display settings fixed it. So I simply unplugged the power supply to the external Dell monitor, let it sit for a few seconds, and plugged it in again. No other changes on the computer, no unplugging of the TB-Display Port cable, just the power cord. Once I plugged the power cord of the Dell monitor in again, it was displaying as usual.

Maybe the problem is coming from the monitor and not from the MBP or the drivers, or it's some sort of communication problem with the monitor just becoming unresponsive after a period of inactivity.

Uh, you might want to read this.

If your EFI firmware was h4cked prior to El Cap being installed, how would you know if it was or wasn't? You could reinstall your system an infinite number of times with clean installs, and it wouldn't matter. If the firmware was hacked correctly, you could never unhack it.

Yep, anyone whose machine got owned due to the firmware hacks that were going around? This is why they made El Cap rootless. This is why they tightened up security so much. Because they knew that our machines were all sitting ducks after that 0day and they didn't tell us.

And think how many people are still on pre-El-Cap systems... could get real ugly...

This is way beyond my technical knowledge and ability. I assume you're saying that this EFI issue could be responsible for the sleep-wake issues we're talking about in this thread. Maybe I should get this Darwn kext described in the link and check the registry. Given the pattern, though, I highly doubt that our problems with sleep-wake are related to a hack like this.

And the writer says that the late model MBP Retinas should not be affected. I have mid 2014 15" rMBP, 11,3. so I should be OK, right? And he says that general users shouldn't be worried about it--mainly just targeted users.
