我觉得我还是另辟一个新帖……https://www.ubuntu.org.cn/viewtopic.php?f=126&t=475159

vickycq 写道:
无论是 pm-suspend 还是 systemctl suspend 都提供众多调试选项，也可以在进入待机/唤醒时运行自定义脚本，对捣乱的设备/模块加以“特殊关照”。


昨晚我碰到了……
此次出现这问题，我记得之前做过一个操作：执行sudo apt-get autoremove把已不再使用的旧内核删除了。
因为我的笔记本在这3天中已使用过多次待机，都很正常，惟有当旧内核被删除后的这次待机——失败了

我让系统挂起后，它立即又自动唤醒了，完整的事件日志信息如下：

为了解决此问题，我在网上找了条命令（http://askubuntu.com/questions/552345/can-not-suspend-my-laptop-asus），运行后，再suspend，就成功了
代码:
先查看一下：
kashu:/var/log$ for i in XHC EHC1 EHC2; do grep $i /proc/acpi/wakeup | grep enabled; done
XHC     S4   *enabled   pci:0000:00:14.0
EHC1     S4   *enabled   pci:0000:00:1d.0
EHC2     S4   *enabled   pci:0000:00:1a.0

kashu:/var/log$ for device in XHC EHC1 EHC2;do grep $device /proc/acpi/wakeup|grep -sq enabled && echo $device|sudo tee /proc/acpi/wakeup;done


我在网上查了一下，最好把脚本写入到/etc/pm/sleep.d中：
http://thecodecentral.com/2011/01/18/fi ... orking-bug

我想说的是，这种N多年前就已出现的老问题，却始终并反复在新版本的Ubuntu/Xubuntu（包括LTS版本）中能遭遇到，而且是很多人能遇到……
包括大家很熟悉的笔记本屏幕亮度无法保存的问题，N多年前开始就有这问题

到底是系统制作商漫不经心的缘故？还是这种问题的处理对系统制作商而言是心有余而力不足呢？或者这是用户的错误？
我觉得想要用好Xubuntu/Ubuntu确实不是很容易，对于新手而言，碰到的困难会更多。但我还是想继续用…… :Haha

我觉得我还是另辟一个新帖……https://www.ubuntu.org.cn/viewtopic.php?f=126&t=475159

vickycq 写道:
无论是 pm-suspend 还是 systemctl suspend 都提供众多调试选项，也可以在进入待机/唤醒时运行自定义脚本，对捣乱的设备/模块加以“特殊关照”。


昨晚我碰到了……
此次出现这问题，我记得之前做过一个操作：执行sudo apt-get autoremove把已不再使用的旧内核删除了。
因为我的笔记本在这3天中已使用过多次待机，都很正常，惟有当旧内核被删除后的这次待机——失败了

我让系统挂起后，它立即又自动唤醒了，完整的事件日志信息如下：

为了解决此问题，我在网上找了条命令（http://askubuntu.com/questions/552345/can-not-suspend-my-laptop-asus），运行后，再suspend，就成功了
代码:
先查看一下：
kashu:/var/log$ for i in XHC EHC1 EHC2; do grep $i /proc/acpi/wakeup | grep enabled; done
XHC     S4   *enabled   pci:0000:00:14.0
EHC1     S4   *enabled   pci:0000:00:1d.0
EHC2     S4   *enabled   pci:0000:00:1a.0

kashu:/var/log$ for device in XHC EHC1 EHC2;do grep $device /proc/acpi/wakeup|grep -sq enabled && echo $device|sudo tee /proc/acpi/wakeup;done


我在网上查了一下，最好把脚本写入到/etc/pm/sleep.d中：

我想说的是，这种N多年前就已出现的老问题，却始终并反复在新版本的Ubuntu/Xubuntu（包括LTS版本）中能遭遇到，而且是很多人能遇到……
包括大家很熟悉的笔记本屏幕亮度无法保存的问题，N多年前开始就有这问题

到底是系统制作商漫不经心的缘故？还是这种问题的处理对系统制作商而言是心有余而力不足呢？或者这是用户的错误？
我觉得想要用好Xubuntu/Ubuntu确实不是很容易，对于新手而言，碰到的困难会更多。但我还是想继续用…… :Haha

一种说法是"自由软件的开发者就是其用户"
另一种说法是Ubuntu这类商业支持的发行版会故意留一些坑来引诱用户购买他们的技术支持.

以前编译内核时,/boot目录下提供的内核配置文件居然还是有微小错误的...(虽然错误微小但影响可不小,折腾了一段时间才成功编译装上能用的内核)
