I recently upgraded to kubuntu 9.04. Everything was fine, until i shutdown the computer: the screen went black, but neither the monitor or computer shut down. so i powered it off manually.
I rebooted the computer, and after the "kubuntu" screen comes up, the screen went black again, and hung there.
I rebooted again in recovery mode, and it hung again.
So how do i even get into KDM or the base OS? also, why won't it shut down??
i was able to fix this by using GDM instead of KDM.
