如何从OSX 10.7.4的显示睡眠中唤醒? [英] How do I wake from display sleep in OSX 10.7.4?

问题描述

在最新版本的OSX Lion中，如何从显示睡眠中唤醒计算机?这是对网络活动的响应.

In the most recent version of OSX Lion, how do you wake up the machine from display sleep? This is in response to network activity.

在10.7.3中，可以通过以下调用来实现:

In 10.7.3 this was possible with the following call:

IOPMAssertionID id = 0;
IOPMAssertionCreateWithName(kIOPMAssertionTypeNoDisplaySleep,
                            kIOPMAssertionLevelOn, reason, &id)

但是，这在10.7.4中不起作用.可以做什么呢?

However, this does not work in 10.7.4. What can be done instead?

推荐答案

我尚未测试性能影响或与空闲计时器本身的交互，但是:

I have not yet tested the performance implications nor the interaction with the idle timer itself, but:

io_registry_entry_t regEntry = IORegistryEntryFromPath(kIOMasterPortDefault, "IOService:/IOResources/IODisplayWrangler");
if (regEntry != MACH_PORT_NULL) {
        IORegistryEntrySetCFProperty(regEntry, CFSTR("IORequestIdle"), kCFBooleanFalse);
        IOObjectRelease(regEntry);
}

在10.7.4中工作，以将屏幕从空闲状态唤醒.

works in 10.7.4 to wake the screen from idle.
