编辑于 14/3 晚上 10 点 我一直在尝试查看是否是 docker 导致的，因为我运行了很多东西，而且它是唯一触发崩溃的进程。我尝试重新安装并清除它
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
但错误仍然发生。以下是一次崩溃的 Kern.loghttps://pastebin.com/jZDBa5gb

我可以通过在分离模式下启动 docker-compose 中的某个容器（在后台运行容器）来始终重现此错误。我有其他不会导致该错误的项目。
还请注意，如果可能相关，在所有会话崩溃和几次重启的某个时刻，我的锁屏现在也再次正确加载了。我没有尝试修复这个问题，也没有亲自做任何我期望改变它的事情。后来我发现了这个问题，它显示了我看到的登录信息（尽管 gnome 灰色的登录信息有黑色背景）Ubuntu 16.04 上奇怪的锁屏
原始问题
我很快就看到了我认为是 fsck 运行的内容，显示干净，然后我需要登录到新会话，丢失之前所做的一切。我不确定该看什么来解决这个问题。
如果我让机器连续几天开机，这种情况会更常见，但这可能是我的错觉。最近一次会话丢失，我上次重新启动时显示是 2 天前。
reboot system boot 4.15.0-88-generi Tue Mar 10 22:33 still running
我在通过 USB SSD 运行 Ubuntu 16.04。
我最近第一次更新了 chrome（我是 linux 新手），我丢失了好看的锁屏，我猜是 lightDM 在更新时搞砸了，我并不担心，但可能与此有关。它弹出关于 GRUB 的提示，我说没有变化或类似情况，然后安装继续。Chrome 现在是最新的，可以正常工作。安装 chrome 的 Bash 历史记录：
sudo apt-get update
apt list --installed | grep 'chrome'
sudo apt-get upgrade google-chrome-stable
我的笔记本电脑上的蓝牙已关闭，我刚刚收到此错误（在日志中查看）但我的桌面上有一个无线鼠标。
sudo less /var/log/syslog（详细但希望我已经发现了其中的问题）：

答案1
通过查看您的日志并查看问题描述，很难确定任何一个原因。错误无处不在。
该系统看起来不像是普通的 16.04 系统，因为我看到了对 gnome-session 的引用，如果我没记错的话，它直到很晚的系统才出现。
在我推荐全新安装 Ubuntu 之前，让我们先检查一下几件事。
记忆
然后，转到https://www.memtest86.com/并下载/运行他们的免费记忆测试来测试你的记忆力。至少完成一次所有 4/4 测试以确认记忆力良好。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。执行sudo dmidecode -t 1,2和sudo dmidecode -s bios-version，并将该输出添加到您的问题中。告诉我您计算机的确切品牌/型号。
- 更新 #1：您拥有的版本是 74CN44WW (V3.05)。您的联想 IdeaPad Y510P 的最新 BIOS 是版本 74CN47WW (V3.08)，可从以下网址下载这里。更新 BIOS 之前请对重要文件进行备份。
