Redshift 是一个有意思的小程序，它能根据你的环境来调节电脑屏幕的色温。如果你长时间坐在电脑前盯住屏幕，那么使用 Redshift 可使你的眼睛免受更大的伤害。

Archlinux：

yaourt -S redshift

然后添加到自启动

安装virtualbox虚拟机软件及附加组件

yaourt -S virtualbox virtualbox-guest-iso

将当前的用户添加到 vboxusers 用户组中：

sudo gpasswd -a sandy vboxusers

VBOX_USB=usbfs

sudo pacman -S cups-pdf
sudo systemctl enable cups.service
or 
sudo systemctl start cups.service

用浏览器访问
http://localhost:631/

添加发现的pdf虚拟打印机-》打印机类型选Generic, Postscript Printer。依照指示走就ok。提示你输入帐号密码请输入root及root密码。

可以测试一下，和windows下的打印机不同的是它默认会把pdf文件输出到一个目录里。默认是

/var/spool/cups-pdf/$用户名/ ;可以自己修改配置文件/etc/cups/cups-pdf.conf 设置默认目录。
效果不错;

安装了archlinux64位，使用systemctl enable不了alsa，提示无install选项

手动链接服务

sudo ln -s /lib/systemd/system/alsa-store.service /etc/systemd/system/multi-user.target.wants/alsa-store@.service

sudo ln -s /lib/systemd/system/alsa-restore.service /etc/systemd/system/multi-user.target.wants/alsa-restore@.service

#一般hosts文件在Windows下位于c:\windows\system32\drivers\etc\hosts。Linux下位于/etc/hosts

下了个压缩包，右键设置打开方式，第一次设置错了，但是这个方式却留在里 右键菜单里面;另外，安装里playonlinux，右键里出现了notepad，卸载playonlinux后，notepad菜单还在。请问如何编辑右键菜单呢？

找到了 
在 ~/.local/share/applications/文件夹下，删除不用的打开方式即可

安装pidgin
$sudo pacman -S pidgin

yaourt里面 的pidgin-lwqq脚本安装不成功

手动git源代码编译安装

首先安装git

$sudo pacman -S git

然后克隆pidgin-lwqq源代码

$ git clone https://github.com/xiehuc/pidgin-lwqq
$ cd pidgin-lwqq
$ mkdir build
$ cmake ..
$ make
$ sudo make install

最后打开pidgin，添加帐号，选择webqq协议即可
