[SOLVED] After upgrade black screen, mouse pointer visible

[Pit]

Hi! I just upgrade my Kubuntu to 11.04, but I can't login. When I boot it appears a black screen instead the login screen. The mouse pointer is visible, but nothing else.

/var/log/Xorg.0.log says:

(EE) intel(0): Failed to submit batch buffer, expect rendering corruption or even a frozen display: No such device

Any ideas?

Thanks!

Solved!! Problem was old kernel + plasma-desktop uninstalled during upgrade + kubuntu-desktop uninstalled during upgrade
