Finally, I find this describe the common problem....
In my first trying to install karmic via network install script and update to the latest version. I found my desktop refuse to interrupt process with Ctrl + c in ssh. It's really hard to use because I only work with ssh....I was thinking that the debootstrip did not properly configure my system. So I made another try to install via ISO. But the problem did not seem to be fixed. I had to say the problem was disappear in some day's package recently(because I did a daily update). But it was broken again.. I doubt the problem is the settings for kernel in initrd and sshd problem may also relate to that, but I'm not sure.
in my system:
kernel: 2.6.31-5-generic
ssh: Can not job control.
VNC: Can not job control. similar to ssh
local: job control is ok.
