我随机失去工作时间(16.04)

Question

EDIT 14/3 10 to 我一直在尝试看看码头是否是原因，因为我运行了大量的东西，这是唯一的进程触发崩溃。我试着重新安装并清除它

docker system prune -a --volumes
sudo apt-get install --reinstall docker.io
sudo curl -L ttps://github.com/docker/compose/releases/download/1.22.0/docker-compose-uname -s-uname -m -o /usr/local/bin/docker-compose

但是错误还是会发生的。这是其中一个崩溃的Kern.log，https://pastebin.com/jZDBa5gb

EDIT 13/3 11 13

我可以在分离模式(在后台运行容器)中，以分离模式打开某个容器，从而一致地重新创建此错误。我还有其他不会导致错误的项目。

还请注意，如果可能相关，神秘地在所有的会话崩溃和一些重新启动，我现在也有我的锁屏幕加载正确的时间。我没有试图解决这个问题，也没有亲自做任何我希望改变的事情。从那以后，我发现了这个问题，它显示了我看到的登录(虽然gnome灰色的那个有一个黑色的背景) Ubuntu16.04上奇怪的锁屏

ORIGINAL问题

我很快看到了我认为是fsck运行，说干净，然后我需要登录到一个新的会话，失去了我以前做的一切。我不知道该怎么解决这个问题。

如果我让我的机器开几天，感觉会更常见，但这可能是我在玩把戏。最近的一次会话丢失，我运行了最后一次重新启动，它说两天前。

reboot   system boot  4.15.0-88-generi Tue Mar 10 22:33   still running

我在Ubuntu16.04从USB运行。

我最近第一次更新了chrome (我是linux的新手)，我失去了我漂亮的锁屏，我发现lightDM在更新中搞砸了，没有担心，但可能是相关的。它弹出了关于GRUB和我说没有改变或沿着他们的路线和安装继续进行。Chrome现在是最新的和工作的。安装铬的撞击历史记录：

sudo apt-get update
apt list --installed | grep 'chrome'
sudo apt-get upgrade google-chrome-stable

蓝牙在我的笔记本电脑上关闭，我刚刚打开了这个错误(见日志)，但我的桌面上有一个无线鼠标。

sudo /var/log/syslog (详细但希望我发现了这个问题)：

Answer 1

在查看您的日志，并回顾您的问题(S)的描述，这是很难确定任何一个原因。错误到处都是。

这个系统看起来不像一个股票16.04系统，因为我看到了对gnome会话的引用，如果内存满足我的需求，直到更晚的系统才会出现。

在我推荐Ubuntu的干净安装之前，让我们检查一些事情。

内存

然后，转到https://www.memtest86.com/并下载/运行他们的免费memtest来测试您的内存。在所有4/4测试中至少通过一次，以确认良好的记忆力。这可能需要几个小时才能完成。

BIOS

让我们检查一下您的BIOS版本。做sudo dmidecode -t 1,2和sudo dmidecode -s bios-version，并将输出添加到您的问题中。告诉我你电脑的确切型号/型号。

• Update #1：您有74CN44WW版本(V3.05)。您的联想IdeaPad Y510P的最新BIOS是74CN47WW (V3.08)，可以在更新BIOS之前下载这里。做重要的文件备份。
