但现在有一个小问题，如何在登陆框中启用虚拟键盘virtual keyboard？
用的是lightdm，查了相关资料，但仍然不管用。

使用kdm的方法也不行。Re: Virtual Keyboard at Login Screen

If you are using lightdm, xvkbd
then following works
write following in a file "light", and chmod +x light
==========================
/usr/bin/xvkbd -display $DISPLAY&
=============================
edit /etc/lightdm/lightdm.conf to add following line to given section
[SeatDefaults]
greeter-setup-script=/root/light
reboot
same for onboard etc.

Update and a new version of onBoard will install. It includes a few fixes and the ability to specify where onBoard will appear on the screen.
To start onBoard in GDM (Ubuntu) insert the below in /etc/gdm/Init/Default just before exit 0, for KDM (Kubuntu) add to the end of /etc/kde3/kdm/Xsetup
Code:
exec onboard -x 0 -y 470 --size=800x300
Note the numbers will depend on your size of screen so play with them until you are happy.
NOTE:
GDM has to run either as "plain" or "plain with face browser". Configurable in gdmsetup.
For Gutsy users replace all instances of feisty with gutsy
似乎是大家现在很关注的一个bug：

后来找到这个帖子，好使。

这个方法对kvkbd和xvkbd都好使，但不知如何替换成onboard,暂且这样。
Step 1: sudo vi /etc/kde/kdm/Xsetup
Step 2: add kvkdb & to the last line of /etc/kde/kdm/Xsetup
Step 3: save /etc/kde/kdm/Xsetup by typing :wq
Step 4: sudo vi /etc/kde/kdm/kdmrc
Step 5: change UseTheme=true to UseTheme=false (on line 443)
Step 6: save /etc/kde/kdm/kdmrc by typing :wq
