我正在运行 Kubuntu 18.04.4 LTS。当我使用 Libreoffice（当前为 6.0.7.3）Writer 时，它经常导致我的整个系统崩溃。显示屏冻结约一分钟，之后我返回登录屏幕以开始新会话。我无法重现它，但我可以说它在我输入文本时总是发生，没什么奇怪的。
这是我/var/log/syslog重启系统之后的摘录：

答案1
您正在使用旧版本的 LibreOffice；这是最新动态：
并且我建议（不知道问题的原因）按照以下 3 个步骤升级到最新版本，以防它能为您解决问题：
使用以下方式添加 LibreOffice PPA
sudo add-apt-repository ppa:libreoffice/ppa使用以下方式更新您的系统
sudo apt update升级或安装较新的 LibreOffice
sudo apt install libreoffice
然后你就可以出发了。
答案2
我发现有两件事需要检查或更新......
记忆
您的内存数量很奇怪。查看后sudo lshw -C memory我发现您有一个 16G DIMM 和 4G（主板上）。RAM 大小不匹配意味着系统无法使用内存交错来最大化内存速度。假设您自己添加了一个 16G DIMM，我们应该运行内存测试。
笔记：计算机最大支持内存20G。
去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
笔记：在执行 BIOS 更新之前备份重要文件
笔记：确认我拥有适合您计算机的正确网页
您有一个非常旧的 BIOS 版本 N1CET37W (1.05)，发布于 2016 年。当前版本是 2019 年 12 月 12 日的 1.47。
去此网页并下载适用于 Linux 的较新的 BIOS 更新。
答案3
您应该卸载libreoffice-kdelibreoffice 的 KDE 集成包。这将使您的 libreoffice 变得更丑陋但更稳定。
