小弟有个小问题，就是linux下光标比较粗，百度好多网页，也没找到怎么让闪烁的竖着的光标
变细，我知道win下是insert键，可这linux下不是啊，跪求指点
ubuntu: 14.04LTS
1. 先安装 (install using sudo apt-get install dconf-tools
2. 运行dconf-editor
3. indicator->unity->interface->cursor-scale-factor 修改值，范围0.5 ~3.0
其他（没试过)
1. sudo update-alternatives --config x-cursor-theme
2. Choose the number of the theme you want - e.g. 0 for DMZ-White
3. Changing the value here requires a reboot - a logout and login will not suffice.
