我有一台 Helios Acer Predator 300 电脑（Predator-G3-572），最近进行了硬件更新，安装了 1Tb SSD。这大大提高了性能，提高了机器效率，无论是工作（因为我是开发人员）还是游戏。
然而，我开始注意到一个问题，现在系统似乎无法正常工作了，记录了一个非常大的系统日志文件（我删除的最后一个文件大约有 50GB）。
更新：
我认为问题可能出在 logrotate 上。为了进行分析，我去检查了 logrotate 程序是否正常工作。起初所有设置都正常，但现在 syslog 文件大于 1 MB，而它应该以 100 KB 为单位进行旋转。
例如，一日日志：

Ele inclui um gerenciador de biblioteca, conversor de formatos, conversor de feeds de notícias em e-book assim como recursos de sincronização de leitores de e-book.#012#012Calibre é principalmente um programa catalogador de e-books. Ele gerencia sua coleção de e-books. Ele foi desenhado ao redor do conceito de livro lógico, isto é, uma única entrada no banco de dados pode corresponder a e-books em vários formatos. Ele também dá suporte a conversão de dúzias de diferentes formatos de e-books para LRF e EPUB. Uma interface gráfica para o software de conversão pode ser facilmente acessada simplesmente clicando no botão "Converter e-books".#012#012Os formatos de entrada para os quais há suporte são: MOBI, LIT, PRC, EPUB, ODT, HTML, CBR, CBZ, RTF, TXT, PDF e LRS.#012#012Calibre possui um desenho modular de driver de dispositivo que torna fácil adicionar suporte para diferentes dispositivos de leitura eletrônica. No momento, ele possui suporte para SONY PRS 500/505/700 e iPhone (com o software "stanza" de leitura). A sincronização dá suporte à atualização de metadados no dispositivo a partir de metadados na biblioteca e à criação de coleções no dispositivo baseada em etiquetas definidas na visualização da biblioteca. Se um livro possui mais de um formato disponível, o calibre escolhe automaticamente o melhor formato quando for enviá-lo para o dispositivo.#012#012O calibre pode automaticamente obter notícias de vários sites web e feeds RSS, formatar as notícias em um e-book e carregá-lo em um dispositivo conectado. Há suporte para geração de e-books LRF/EPUB. Os e-books incluem as versões *completas* dos artigos, não apenas os sumários.#012#012O calibre também possui um visualizador embutido de e-book que pode exibir todos os principais formatos de e-book.#012source-00: calibre#012source-id-00: calibre;3.21.0+dfsg-1build1;all;ubuntu-bionic-universe#012url{homepage}: http://calibre-ebook.com#012license: LicenseRef-free=https://www.ubuntu.com/about/about-ubuntu/licensing#012license-is-free: yes#012management-plugin: packagekit#012origin: ubuntu-bionic-universe#012origin-appstream: ubuntu-bionic-universe#012reviews: 0#012provides: 0#012install-date: 1#012size-installed: unknowable#012size-download: 24,7 MB#012category: Graphics#012category: Viewer#012{GnomeSoftware::Creator}: appstream#012{appstream::source-file}: /usr/share/applications/calibre-lrfviewer.desktop

配置Logrotate：
# see "man logrotate" for details
# rotate log files weekly
weekly
# use the syslog group by default, since this is the owning group
# of /var/log/syslog.
su root syslog
# keep 4 weeks worth of backlogs
rotate 4
# create new (empty) log files after rotating old ones
create
# uncomment this if you want your log files compressed
#compress
# packages drop log rotation information into this directory
include /etc/logrotate.d
# no packages own wtmp, or btmp -- we'll rotate them here

答案1
在查看您的 时syslog，我很容易就发现了许多问题。我将以这个答案的形式记录其中一些问题，因为有太多内容无法放入评论中。
笔记：请将所有输出作为对您的问题的编辑，而不是评论。
CPU 过热 mce：CPU6：封装温度高于阈值，CPU 时钟节流（总事件数 = 6796）
MCE 是机器检查错误。通常不是什么好事。它很脏/满是灰尘吗？
您是否对这台计算机的 CPU/RAM 进行了超频？
GNOME Shell 崩溃
- 你有一个或多个 GNOME Shell 扩展崩溃了……我认为 TopIcons 是可能的
- 给我看看
ls -al ~/.local/share/gnome-shell/extensions - 给我看看
ls -al /usr/share/gnome-shell/extensions
drawnio应用程序
- 生成大量系统日志输出
- 表示有可用更新
- Snap 应用程序？
- 可能是字体问题
字体问题
- Snap 应用程序可能存在问题吗？
- 给我看看
snap list - 您是否安装了任何字体或与字体相关的应用程序？
答案2
您可以尝试从 Ubuntu 软件中心安装 Stacer。
系统会自动生成许多系统日志文件，但进行一些常规管理总是有好处的。系统日志文件在其他情况下也很有用。
定期选择系统清洁器选项以保持系统整洁。
