desktop effects cannot be read [run]

[gnomek]

After some update like a month ego desktop effects stoped working the way I configured them. When I want correct it in system settings I get information that cannot be read (run).

I have no idea why. Alt+Tab still switches between running applications. But I can't set new settings.
I deleted kwinrc and restarted but it didn't help.

Could you...

Could you show the error message ?

Could you tell something of your system - GPU ?

Could you tell your compositing etc. settings ?


If I turn the compositing to the XRender the error is:



and the ~/.cache/upstart/startkde.log has:

kwin(3009) KWin::EffectsHandlerImpl::loadEffect: EffectsHandler::loadEffect : Effect "kwin4_effect_blur" is not supported

Just for the record, here is a link for information that I got.

Thank you for your tip. It appeared that the problem was caused by OpenGL that couldn't be initialised.

I changed it to XRender and now everything works fine.
