英特尔无线功能仅在 16.04 版上 acpi=off 时才有效

英特尔无线功能仅在 16.04 版上 acpi=off 时才有效

我最近购买了全新的 ThinkPad X1 Carbon 第四代,尝试设置 Ubuntu 16.04(撰写本文时为 beta 2)。

无法使无线和 ACPI 正常工作一起,它们有点互相排斥:

  1. 无线功能只有acpi=off在传递到内核时才能正常工作
  2. 但是如果acpi=off设置了,整个电源管理系统就会关闭,结果就是没有电池状态,没有挂起到 RAM,没有音频(由于某种原因,它在 ACPI 开启时工作),等等

有没有线索说明为什么无线功能只有在acpi=off设置时才有效?我需要摆脱它,acpi=off因为我需要电源管理。

答案1

要同时获得 ACPI 和无线工作,请使用acpi=force选项而不是acpi=off
