我有一台戴尔 Inspiron 1525。暂停和恢复功能工作正常。
突然间，当我点击suspend菜单选项时，系统并没有被暂停。相反，它被锁定了。查看dmesg输出显示

特别是usbhid 6-2:1.0: suspend error -5。Google 没有找到任何有用的信息。
我该如何进一步解决此问题？
答案1
线路
PM：设备 6-2 挂起失败：错误 -5
表明该设备在挂起时存在问题。您可以通过执行 lsusb 并查看它来找出总线 6.2 上的情况。如果问题仍然存在，请使用“ubuntu-bug linux”提交错误报告
答案2
我认为输出中早些时候可能会有线索dmesg。
做
dmesg -T|grep Freez -A4
寻找停止暂停的特定进程，它会给出什么结果吗？
在这种情况下，请参阅我的回答：如何使“暂停”选项发挥作用？关于如何在暂停之前自动终止它们。
