dell mini9 fluxbox 亮度的调节和 wireless 无线网卡的安装

wskickahn

通过修改首先到 sys/devices/virtual/backlight/acpi_video0/
然后 sudo -s　　然后 sudo echo -n 3 > brightness
　　就可以修改mini9的亮度了，范围是0－15， 上面的>前后一定要加空格
　　
　　安装的是ubuntu server 8.0
　　

首先是弄到wireless driver的两个包　　broadcom-sta-source_5.10.91.9.3-1_all.deb
　　broadcom-sta-common_5.10.91.9.3-1_all.deb
　　
　　使用dpkg安装这两个包

$ su
# dpkg -i broadcom-sta-*deb
这个地方我的ubuntu server会出现要求7.0以上的debhelper，可以自己下载安装
也可以下载一个debhelper7.0的deb包　　然后首先apt-get install debhelper
　　由于ubuntu的最新的debhelper是6.0，所以我们可以使用6.0的debhelper来安装debhelper 7.0
　　
　　然后首先安装
　　apt-get install module-assistant
　　apt-get install build-essential
　　apt-get install quilt
　　apt-get install wireless-tools



# m-a a-i broadcom-sta


# modprobe wl
Verify your device has an available interface:

　　使用下面的命令，查看网卡信息，比如网卡名称

# iwconfig


安装软件


wpa_supplicant


# apt-get install wpasupplicant
WPA-PSK and WPA2-PSK
Also known as "WPA Personal" and "WPA2 Personal" respectively.


Restrict the permissions of /etc/network/interfaces, to prevent pre-shared key (PSK) disclosure:


# chmod 0600 /etc/network/interfaces
Open /etc/network/interfaces in a text editor:


# vim /etc/network/interfaces
Define appropriate stanzas for your wireless interface, along with the SSID and PSK. For example:


auto wlan0    //这个位置注意，wlan0的名字应该替换为我自己iwconfig以后出现
iface wlan0 inet dhcp    //的名字，我自己目前的就是eth1
wpa-ssid mynetworkname
wpa-psk mysecretpassphrase
The "auto" stanza will bring your interface up at system startup. If not desired, remove or comment this line.
Save the file and exit the editor.
Bring your interface up. This will start wpa_supplicant as a background process.


# ifup wlan0
Additional wpa-* options are described within /usr/share/doc/wpasupplicant/README.modes.gz. This should also be read if connecting to a network not broadcasting its SSID.
