Bug Description
After upgrading to KDE 4.5 using the Kubuntu backports after a normal reboot (no crashes), Kwin composition was broken. If I activate and deactivate the composition I get this message in the notification icon:
The following desktop effects could not be activated:
Blur
Desktop Cube Animation
Sticky Windows, etc., etc, etc....
If I change the composition method to Xrender it works just fine. But if I return to OpenGL I get the message mentioned. If I disable the functionality verification and try OpenGL I get a completely black screen.
I have an Nvidia GeForce GTS 360M card using the official Nvidia drivers (256.35). Kubuntu 10.04 x64. No problems before this update, I haven't changed the Nvidia driver in a couple of months so this bug must have relationship with the KDE 4.5 update.
If you need more information just ask for logs (giving me the place to look for them :) please)
PD: One day before this behavior I worked with an external monitor. After using it everything appeer to be working ok. Im not sure if this can have any relation.

similar situation here. I even reinstalled Kubuntu from scratch. It worked fine, but as soon as KDE 4.5 is loaded - compositing is gone.
I tried enabling Xrender which works but is extremely slow. After enabling Xrender I cannot switch back to the OpenGL, so I have no compositing at all.
I tried compositing with radeon drivers and with oficial ATI drivers, but nothing worked.
I have ATI HD Radeon 4670 on Dell Studio XPS 1645 with i7 CPU, running Kubuntu 10.04 x64
