KDE black screen

Hey, I got a kde strange behaviour. Im using Fedora Core 9 and I have two desktops installed, gnome 2.22 and KDE 4.0.5 (last update). When I try to login using KDE desktop everything works fine until start splash screen is seen and login sound heard, as screen changes and went back to black and only arrow cursor works. All black! If I click at lower right display I can hear a sound, but nothing happens.
I have tryied to reinstall (yum reinstall kdebase), no changes. What can I do? Although Gnome is a good desktop, I prefer KDE. Any guess?

same same

Hello,

I did a fresh install of FC9 today on my fairly old system...

Everything seemed to be ok and I got the same issue that you two have.

Just can imagine that there is a faulty packet in the update. Can't be a Nvidia problem, thus gnome is still fine.

Hope there is help for us...

It used to work for me for about a day, but after I tried to reinstall a driver (lost the nvidia splash screen) I got the black KDE. I tried to use old xorg.conf, reinstall the nvidia driver, remove the driver, generate a new xorg... nothing worked.

same...

Did a fresh install of Fedora 9 today, everything was working fine. I let the update manager do all the updates, that took about 4 hours. After rebooting I am getting a black screen with a functioning cursor in KDE, and GNOME works fine.

I had very similar problem.
I installed Fedora 9, then many additional applications from official Fedora repository and Livna and then I let the system do all updates.
When all updates had installed I had black screen in KDE after log in (I saw only splash screen for a while).

After long searching and combining with KDE config files I realized that problem is caused by composite effects in KDE.
I modified file ~/.kde/share/config/kwinrc line:

[Compositing]
Enabled=true

to

[Compositing]
Enabled=false


I remember that after installation I manually turned on composite effects in "System settings" -> "Desktop" -> "Composite effects".

Everything went back to normal operation. I suppose that my graphic card or drivers are guilty too, because I have an old GeForce 2 MX400 and use out of the box Fedora's drivers without 3D.

Hope it helps.
