装过几个桌面环境之后，发现原来的登录界面的光标颜色由白变黑了。找来找去最后在一个bug贴里找到方法.

$ sudo update-alternatives --config x-cursor-theme
There are 7 choices for the alternative x-cursor-theme (providing /usr/share/icons/default/index.theme).

Selection Path Priority Status
------------------------------------------------------------
* 0 /etc/X11/cursors/oxy-white.theme 50 auto mode
1 /etc/X11/cursors/core.theme 30 manual mode
2 /etc/X11/cursors/handhelds.theme 20 manual mode
3 /etc/X11/cursors/oxy-white.theme 50 manual mode
4 /etc/X11/cursors/redglass.theme 20 manual mode
5 /etc/X11/cursors/whiteglass.theme 20 manual mode
6 /usr/share/icons/DMZ-Black/cursor.theme 30 manual mode
7 /usr/share/icons/DMZ-White/cursor.theme 50 manual mode

Press enter to keep the current choice[*], or type selection number:

As we can observe above oxy-white (the KDE cursor theme) is set to automatic mode and status of 50. Would it not resolve the bug to change this value or switch it to manual mode by default? Another idea is to have debconf ask the user for which cursor they would like although I like this idea less because it will not allow a seamless installation of kubuntu-desktop.

 看了一下自己电脑上的x-cursor-theme，发现当前是指向的oxy-black.theme 手动指为oxy-white.theme. 重启后进入login界面，OK，光标终于恢复成白色了。
