kde killed everything

[konsta82]

I just installed kde enviroment on my ubuntu 9.10.
Command I used is sudo aptitude install kde-desktop.
After grub screen there is only black screen now.
What to do to run kde or at least revert gnome ?
Any ideas ?

What if I take recovery mode and enter aptitude remove kde-desktop
Will my gnome come back or it is deleted ?
