KDE desktop-effects not working

[Yves Glodt]

Using maverick on amd64, fully upgraded, KDE desktop-effects do not work since some time.

When trying to enable them via kwin config I get this information:

"Desktop effects are not available on this system due to the following technical issues:"

But no issue is listed.

Log when launching kwin manually:

kwin() KWin::Workspace::setupCompositing: Initializing OpenGL compositing
kwin() KWin::Workspace::setupCompositing: KWin has detected that your OpenGL library is unsafe to use, falling back to XRender.
kwin(): Failed to initialize compositing, compositing disabled

For debugging I tried to run glxgears, which work,s but only at 280 fps

Xorg log shows nothing suspicious.

In case it could be useful, here Xorg.log.

Maybe the latest release of xf86-video-ati (6.13.2 from yesterday) would help:

I reported a similar bug today and I've been trying to find it (with no success) so that I can give an update: I have found that I can get desktop effects to work by clearing the 'enable functionality checks' checkbox. I hope this is relevant, please ignore if it isn't.

Same on natty. Any more information you need from my system?

Hi there!

Thanks for reporting this bug! Your bug seems to be a problem with the KDE program itself, and not with our KDE packages. While we appreciate your issue, it would be better if it was tracked at https://bugs.kde.org, so that the KDE developers can deal with this speedily and have direct communication with you as the reporter for more effective debugging.

Thanks!
