我在我妈妈的旧机器上安装了 ubuntu 14.04，但遇到了一个奇怪的问题。电脑无法挂起。屏幕可以正常关闭，但当电脑应该挂起时，屏幕却唤醒了。当我使用时也发生了同样的事情pm-suspend，屏幕关闭不到一秒钟，屏幕上出现一些行的速度太快，我来不及看清，然后屏幕又打开了。
我检查了acpitool -w一下，结果如下
1. LANC S4 *disabled
2. P32 S0 *disabled pci:0000:00:1e.0
3. KBC S3 *enabled pnp:00:03
4. MOUE S3 *disabled pnp:00:04
5. CIR0 S5 *enabled pnp:00:05
6. EXP2 S5 *disabled pci:0000:00:1c.1
7. PXSX S5 *enabled pci:0000:03:00.0
8. EXP6 S0 *disabled pci:0000:00:1c.5
9. PXSX S0 *disabled
我设法通过 upstart 脚本 KBC 和 CIR0 禁用它，但没有成功。尽管有脚本，PXSX 仍保持启用状态。
我也尝试断开连接到计算机的所有 USB 设备，但没有任何变化。
/var/log/pm-suspend.log这是我执行命令后文件的最后一项pm-suspend。我试图理解它，但它超出了我对 Linux 的理解。

以防万一我也更新了我的视频卡驱动程序，因为我不知道还能做什么。
