Black screen after upgrading to KDE 4.5

[candide]

I'm under Kubuntu 10.04 and I upgraded kde from 4.4 to 4.5. via apt-get.
After login, I got a black screen with the mouse cursor visible. I have no idea how to fix this.

Can anyone provide some guidance ?

From where you are - black screen with mouse cursor - press Ctrl+Alt+F1 to open a console. Login and the type:

sudo apt-get update && sudo apt-get install plasma-desktop

Once that completes, press Ctrl+Alt+F7 to return.

sudo apt-get update && sudo apt-get install plasma-desktop

Thanks for your response.

The system tells me that plasma-desktop is yet the last version available. Another suggestion ?

Can you open a consle? Press Alt+F2. Does Krunner appear? If it does, type konsole and press enter. In the console that appears, type:

plasma-desktop

If your desktop appears, great. If it does not, then take a look at Plasma, plasmoids and short how to recover posted by Rog131 (a real guru here!). Scroll down to Reset only the plasma desktop. You will want to try this from the tty1 console.
