小黑真的老了 降降温.....

|

 先是给小黑换了个键盘,五年了键盘已经不灵活了,然后....跑"瘟到死"的"差批"也跑不动了.经过两天反复不停的折腾,在小黑上就是种不上"黑苹果",换了十几个版本就是不行...... 郁闷啊

想来想去还是装Ubunt ,不过好像散热现在是个大问题,那一个叫热,今天安装了个监控温度的小插件,

sudo aptitude install lm-sensors sensors-applet

一看天!! CPU 92 GPU 89 .... 那叫一个热! 放狗找,看到个可以设定CPU频率的小东西,不错!

 

sudo aptitude install cpufrequtils

tea@tea-laptop:~$ cpufreq-info

analyzing CPU 0:
  driver: acpi-cpufreq
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency: 20.0 us.
  hardware limits: 800 MHz - 2.00 GHz

  current policy: frequency should be within 800 MHz and 1.07 GHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
  current CPU frequency is 800 MHz.

cpufreq-set

Allows setting

-d  minimum frequency,
-u maximum frequency,
-f specific frequency (userspace governor must be set first) and
-g governor on a
-c specific CPU.

cpufreq-set needs root privileges in order to work.

Activate the conservative governor to save a little extra power by letting the CPU stay longer at each frequency step before changing:

user@host:~$ sudo cpufreq-set -g conservative

Set the upper frequency limit to 1.6Ghz:

user@host:~$ sudo cpufreq-set -u 1.6Ghz

Manually set the frequency to a constant 800Mhz (userspace governor):

user@host:~$ sudo cpufreq-set -g userspace
user@host:~$ sudo cpufreq-set -f 800Mhz

 现在我设定的是1.06Ghz 温度下来了 . 52 - 68之间
