ubuntu 9.10 starts in console tty1 and later grafical mode very slow

Yesterday I was instaling kaffeine0.8.7, kdelibs4c2a, python-qt4, to watch de terrestian tv on my pc.

And I copy and script to start a tv card when computer starts on /etc/udev with permissions. But I delete the script ubication.

Today my computer is very slow and when starts in console "ubuntu 9.10 tt1" login:

I try to kill some process because the use of memory is high. But meaby no the correct process the problem persist.

I try this: sudo /etc/init.d/gdm stop
               sudo /etc/init.d/gdm start

But nothing.
