Question

KDE baloo 最近导致rsyslog开始记录许多错误。

它导致我/var/log/syslog呈指数级增长，它已经填满了磁盘一次，此后我已禁用rsyslog以阻止它破坏我的 SSD 并使 Ubuntu 无法使用，但我不知道 Baloo 是什么或如何停止和卸载它。当我注意到这/var/log/syslog已经增长到 66GB 导致我的磁盘已满时。我能够删除它并重新登录并rsyslog通过恢复模式禁用。运行rsyslog一秒钟使其上升到75MB。

'Neofetch --off' 结果

我不想立即卸载整个 KDE，但如果这是摆脱这个损坏程序的唯一方法，那么我很乐意。

这停止rsyslog填充/var/log/syslog。

谢谢，哈利

Answer 1

对我来说，它只是帮助禁用内容索引，如下所示：

balooctl config set contentIndexing no

这样，baloo 应该很快就可以为文件名建立索引，这样你仍然可以在 Dolphin 中搜索文件名。

Answer 2

这是我删除 baloo 的方法

balooctl disable                  # stops the service
sudo apt install -s dolphin       # where to find baloo
sudo apt remove --purge libkf5balooengine5
rm -rf .local/share/baloo/        # removes the index files; they can be several GB

Baloo 上有一些相关的答案，创建 64GB 索引，占用我一半的内存和 25% 的 CPU
