1.修改/etc/default/acpi-support

ENABLE_LAPTOP_MODE=true

2.修改 /etc/laptop-mode/laptop-mode.conf

交流电模式下使用 laptop mode
#
# Enable laptop mode when on AC power.
#
ENABLE_LAPTOP_MODE_ON_AC=1
＃电池那也可设为1

使用 laptop mode 进行LCD亮度控制
#
# Should laptop mode tools control LCD brightness?
#
CONTROL_BRIGHTNESS=1

#
# Commands to execute to set the brightness on your LCD
#
BATT_BRIGHTNESS_COMMAND="echo 0"
LM_AC_BRIGHTNESS_COMMAND="echo 9" 
NOLM_AC_BRIGHTNESS_COMMAND="echo 9"
BRIGHTNESS_OUTPUT="/sys/class/backlight/acpi_video1/brightness"

如果你不明白上面的设置的意思，可以参考下面的说明

＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
# * If your system has the file "/proc/acpi/video/VID/LCD/brightness" (VID may
# be VID1 or similar), use this file as BRIGHTNESS_OUTPUT, and use
# the command "echo <value>". The possible values can be listed using the
# command:
#
# cat /proc/acpi/video/VID/LCD/brightness

# * If you have a file /sys/class/backlight/.../brightness, then you can use
# that file as BRIGHTNESS_OUTPUT, and the command "echo <value>".
#
# As far as I understand it the values are between 0 and
# the value contained in the file /sys/class/backlight/.../max_brightness.

把字体(*.ttf)拷贝到/usr/share/fonts，这样gimp也可以用特殊的中文字体了。

我最近养成一个习惯，喜欢在等人等车的时候用手机看一些技术文档。可是我的工作系统是ubuntu，手机又是windows mobile系统的smartphone，所以只有通过bluetooth发送文件。 今天我实践了一下，还是很成功的。下面把主要过程记录一下。

1. pc上安装软件包 apt-get install

* bluez-pin
* bluez-hcidump
* bluez-utils
* gnome-bluetooth

2. 修改 /etc/bluetooth/hcid.conf

将security user 改为 security auto

3. 启动 bluetooth 服务

sudo /etc/init.d/bluetooth start

4. 将575的蓝牙开启，注意状态是：“可识别” ，不是“打开”。

5. 输入 #hcitool scan得到手机的device id

e.g. Scanning ...

00:01:EC:0C:D2:00 HTC Smartphone

下面还可以做一个测试，是ubuntu蓝牙开发组的测试 https://wiki.ubuntu.com/Bluetooth/TestPlan

6. 将开始-设置-无线数据交换，把里面的“接收无线书记交换内容”的勾，勾上。（这步，我没有做，一直失败。）

7。通过gnome-obex-send发送

#sudo gnome-obex-send -d 00:01:EC:0C:D2:00 file

（看网上资料，obex可能有bug，有的系统可能需要先运行 #hciconfig hci0 inqmode 0 ）

文件缺省发送到 \storage\my documents。

 

补充：

gnome-obex-send 已经被 bluetooth-sendto代替了。

相信ubuntu用户都遇到过这种情况，在编译某些源代码时，
被提示缺少某些库文件，可是由于不知道库在ubuntu源中
具体的名字，无法正确的apt-get install。

现在有一个工具auto-apt可以帮助你解决问题。
首先，安装auto-apt：
  # apt-get install auto-apt

然后，你所要做的仅仅是：
     # auto-apt run command

这里“command”指在运行过程中可能出现“需求文件不存在”问题的命令。例如：
     # auto-apt run ./configure

一会儿，它就会告诉你要安装所需的软件包并自动转到apt-get处理。如果你正在运行X，
就会一个图形界面提示窗口。就这么简单。

1）/etc/sudoers 的属性改成740

2）编辑sudoers, 将最后一行改为

%admin ALL=NOPASSWD:ALL

3）/etc/sudoers 的属性改回440
