upgraded to 10.04 LTS Kubuntu - try login into KDE begins to boot then crashes
 

I upgraded Kubuntu to 10.04 LTS. At login screen I enter my password to login once that harddrive icon comes up it immediatly gives me a black screen then goes back to the login screen.

ive tried deleting everything in /tmp/. i did a sudo dpkg --reconfigure -a, Gnome works perfectly well.

**Just noticed that on grub screen it displays Ubuntu**

Can you get a termional by hitting Ctrl_Alt_F2 or F3?
try a log in there, and it should show you an error.

I would boot on the install cd, change your password, change to runlevel 3 in /etc/inittab. look for the line in /etc/inittab
initdefault:5
and change the 5 to a 3
Then reboot. You can have X by typing startx
