我有一台东芝 Satellite P300-1FO 笔记本电脑，最近我删除了 12.10 并新安装了 13.04。
电脑运行一段时间后，风扇转速异常高。CPU 占用率很低，因此我认为不是过热。
我按照第一个答案这个问题并运行以下命令：
sudo add-apt-repository ppa:linrunner/tlp
sudo apt-get update
sudo apt-get install tlp tlp-rdw smartmontools ethtool
我没有运行任何其他配置命令，我只是想检查温度，这似乎是合理的：
tlp-stat -t

CPU temp = 56 [°C]

编辑1： 按照第一个答案，我安装了 lm-sensors，并在运行“传感器”时得到了以下输出：
acpitz-virtual-0
Adapter: Virtual device
temp1: +57.0°C (crit = +104.0°C)
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +53.0°C (high = +105.0°C, crit = +105.0°C)
Core 1: +54.0°C (high = +105.0°C, crit = +105.0°C)
然后我安装了 fglrx，当我运行“aticonfig”时，我得到了以下输出：
aticonfig: No supported adapters detected

安装 fglrx 并重启后，分辨率降低，Unity 无法加载。我通过运行“sudo apt-get remove fglrx”删除了 fglrx，重启后，计算机恢复到完整分辨率，但 Unity 仍然无法加载。
所以现在我有两个问题：
- 风扇转速不降低
- Unity 无法加载，我必须使用终端来执行所有操作
请指教。
答案1
您应该安装 lm-sensors 包并检查您的 GPU（显卡）...
尝试安装专有的 ati 或 nvidia 驱动程序。在某些配置中，它更有效率。（我有 ati hd 5470，开源驱动程序使我的卡过热 - 一直保持在 80 C 左右 - 并且在低性能模式下性能太低 :) ）
从控制面板/系统设置中的软件中心或软件源安装 fglrx 或 flglrx-updates...
编辑： 您可以通过终端使用“软件中心”，12.10 中有一个关于 unity 和 FGLRX 的错误（我也遇到了），安装 CCSM（compizconfig-settings-manager）并在 OpenGL 插件中禁用同步到 Vblank...然后重新启动系统或直接注销并登录。它应该会回来（unity）
关于 FGLRX，您可以通过 aticonfig --odgt 检查它（温度），同时禁用 ccsm 中的帧缓冲区对象也可以降低温度和 GPU 使用率。尝试查看解决方法插件并使用这些设置。完成所有安装和卸载显卡驱动程序后，不要忘记重新启动整个系统。
对于 unity（再次）尝试 unity 和 compiz --replace 命令，如果您的显卡似乎没有响应所有这些命令，请使用 fglrx-updates 包...
我在 12.10 中看到了“无统一”错误，但在 13.04 中没有看到。祝你好运......
