After latest updates (kernel and various other packages), when I restarted, I couldn't log in to KDE. It starts loading, and gets stuck on the network icon. I tried booting with the old kernel, but the same thing happens. Using Kubuntu 9.04 with KDE 4.2 on a Dell Inspiron E1505 laptop.

I also tried moving the .kde and .kderc folders to see if it will load with fresh settings, but to no avail. Anybody know what's the problem or how to find it?
