Ubuntu Mate 16.04 - VirtualboxGuest 过热

Ubuntu Mate 16.04 - VirtualboxGuest 过热

我有一个安装了 ubuntu mate 的 virtualbox 客户机。从某天起,这个主机就让我的笔记本电脑过热,特别是在使用 Firefox(无 Chromium)浏览或使用 Java 应用程序(即 eclipse)时。

top

确认 CPU 使用率较高。

我尝试了很多帖子建议,但没有合理的结果:

  • 优化 VirtualBox 设置
  • 改变 windowo 渲染: marco -> compiz -> marco compton
  • 重新安装 Java 并彻底清理:openJDK -> java -> openJDK
  • 更新/清除/自动清理
  • 清理 Firefox 配置文件,以安全模式启动
  • ...

现在我没得选择了。这是硬件配置

sudo lshw -sanitize

希望这能有所帮助,你会看到我在 8 个 CPU 中只分配了 2 个,但是 4 个或 6 个没有任何变化:
