Linux Mint 在屏幕锁定时重新启动，我该如何调试/修复它？

Question

很难搜索这个问题，因为有很多关于重启、屏幕锁定等的问题，但我已经看过了，但找不到任何东西，所以就这样了。

我正在使用相对标准的设置运行 Mint 14 (MATE)。我不确定我应该提供哪些其他信息，但我很乐意添加任何有助于解决问题的详细信息。我使用 xscreensaver，只要我只锁定屏幕几分钟，就可以正常工作。但是，如果我离开计算机并锁定屏幕超过 10 分钟，则几乎可以保证计算机会重新启动，从而丢失我打开的所有内容。这非常令人沮丧，我真的需要以某种方式修复它，但似乎没有什么可以追踪这个问题。我尝试使用详细日志记录运行 xscreensaver，但没有明显错误（这是崩溃前的最后 10 分钟左右）：

我真的不希望有人根据这一点确切地知道出了什么问题，但是关于我应该如何尝试追查原因的一些指示将不胜感激。

这10分钟有什么特别之处？也许 DPMS 会发挥作用？您的设置中是否有 10 分钟后过期的超时？

建议：您可以尝试用调试程序暂时替换您的xscreensaver。只是为了给你一些粗略的估计我会做什么（未经测试）：

• 通过输入“which xscreensaver”确定 xscreensaver 的位置
• 备份它并用下面的脚本替换它。这只会休眠而不调用 xscreensaver
• 使您的调试脚本可以通过 chmod 755 执行...
• 重新启动会话并等待 10 分钟到期
• 定期观察机器（它是否已经挂起？）和脚本写入的日志文件（它使用什么参数调用？）

\

#!/bin/sh

exec >> $0.log 2>&1
echo $0 $@
# just wait - don't call screensaver (what does happen?)
sleep 1200
# eventually reenable this after some experimenting:
#<name of backed up xscreensaver> $@
