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
cpufrequtils 006: cpufreq-info (C) Dominik Brodowski 2004-2009
Report errors and bugs to cpufreq@vger.kernel.org, please.
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
available frequency steps: 2.00 GHz, 1.60 GHz, 1.33 GHz, 1.07 GHz, 800 MHz
available cpufreq governors: conservative, ondemand, userspace, powersave, performance
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 stats: 2.00 GHz:55.46%, 1.60 GHz:0.70%, 1.33 GHz:0.81%, 1.07 GHz:1.39%, 800 MHz:41.64% (41245)
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
更新服务器从 Edgy 到 Feisty 选用
使用mirror.rootguide.org做源,服务器在上海,速度很快
