1.修复引导项


如果只是纯粹的装了win7/win8后没有了引导项 可以在win7/win8中用easybcd把/boot添加回来就行了。


要是。。完全把引导弄坏了。可以看一下下面这篇文章。


Reinstall / Recover GRUB from Ubuntu live CD / USB


用ubuntu live装一个叫做boot-repair的东西   点修复  等运行完点ok就行了



sudo add-apt-repository ppa:yannubuntu/boot-repair

sudo apt-get update

sudo apt-get install -y boot-repair

boot-repair





2.ctrl + alt + cursor 切换工作区间


装了ubuntu13.04后第一个最大的感受就是。。我切换工作区间的快捷键怎么没有用了！！


当然先在设置中把workspace打开，还是不行


但在快捷键的列表中看到还是有这几个快捷键。。。最后在ubuntuask上看到了这么一个回答


“I had this same issue. I enabled workspace from
Appearance->Behavior, and also tried using Ubuntu Tweak, but no go on the keyboard shortcuts, even though all the defaults were there.


I then opened CCSM to make sure that the Desktop Wall was enabled. In my case it wasn’t, and as soon as I enabled it, my keyboard shortcuts started working again.”


然后我就装了一下CCSM，把Desktop Wall这个选项勾上。。结果真的完全恢复正常了。





3.更新软件源 

不知道是不是163的源里没有13.04，我直接从12.10升级的时候悲剧了。

然后现在让它自动检测最快的源，现在就用china的第一个源，貌似也挺好用。



4. 双显卡


一开机笔记本就轰轰轰的掉点     就按以前的方法把独显关了算了      intel的独显绝对够用了。


cat  /sys/kernel/debug/vgaswitcheroo/switch


echo “OFF” > /sys/kernel/debug/vgaswitcheroo/switch


可以前好像出现过在ubuntu中把nvidia禁用了   结果win7中也开不起来了。 





5.输入法


以前还装了搜狗的输入法。感觉一般吧


这次在ubuntu中用了谷歌的输入法 真的给了我很大的惊喜


输入时光标终于能跟着拼音动     感觉和windows的体验也没什么区别了。





6.开机的亮度


这肯定都知道吧











The file /etc/rc.local should look like this:


#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will “exit 0” on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
echo 0 > /sys/class/backlight/acpi_video0/brightness
exit 0


Per @zerdo: In my dell studio 1558 the brightness setting is stored in/sys/class/backlight/intel_backlight/brightness.
Just change the path if your computer doesn’t use the acpi_video0 folder.



Also, per @Nick : If this is the only answer you read, note that the 0 in echo
0 is going to be your default brightness setting. I had set this up and it was driving me crazy for a long time : every time I booted up, it would set it to the lowest brightness setting. I prefer mine to start at max brightness, so I used echo
10instead. Your hardware might vary in brightness scale.


sudo gedit /etc/rc.local
在exit 0 前加上
echo 2 > /sys/class/backlight/acpi_video0/brightness


0～10代表不同的亮度。

7.截图小工具 



   
sudo apt-get install ksnapshot



结果后来发现ubuntu有截图的快捷键  



/images/loading/loading_test_ver2.0.gif" data-original="/images/loading/loading_test_ver2.0.gif" data-original="










总之ubuntu还是很棒的   和windows比起来   我更愿意留在ubuntu～
