Hi
I have KDE SC beta 2 and i cannot activate the kwin blur effect. Other effects like wobbly windows or snow work without problems. Are there special requirements for this plugin? For example, I use bespin instead of the default oxygen style (don't know why but oxygen dissapeared during the update) |

Which graphics card driver are you using? My Intel driver seems to be sufficient to run it, and if I recall correctly, the effect does require that the graphics driver can perform certain operations.

I use the Open-Source radeon-driver.
My graphics card is an ati mobility radeon x1400. |

Could you please post the output of glxinfo? That would tell if your driver supports blur or not. Also it might be interesting to see the output from kwin start. So enable 1212 in kdebugdialog and do a kwin --replace & in a konsole. It should say exactly why Blur doesn't work.

Your OpenGL implementation is quite old (only 1.5). So it might be possible that your hardware does not support it. But we had some recent changes which perhaps allow you to use blur in the next version (should be the RC). Nevertheless I doubt that it will be fast.

Blur does not work with the official plugin, but, for example, with this one: http://kde-look.org/content/show.php/BeDistorted?content=126906
(only xrender) My graphics card also supports windows aero. I think it is a bug of the blur-plugin, not my hardware. |

As it says it's only xrender. That means it is done on CPU - not a good idea. And it also states that it is only a proof of concept.
Most likely a bug in the graphics driver. The hardware requirements for Windows Aero and Blur are the same. |

I am having this same exact problem on Kde 4.5 with blur. I am able to use blur on windows 7 so why can't I on kde?

This really depends on the graphics card and driver. The fact that it works on Windows only says that your hardware supports it, but not that the driver supports it. |

Are there other drivers available? I do not know much about ATI. All I know is it is not supported that well on linux.

For Ati cards exist depending on the actual GPU three diverent drivers:
If you have not installed any driver you are using the radeon one. This is in general the best choice but some distributions ship outdated versions which do not yet support the requirements of blur. In that case the fglrx driver might help. If you are using fglrx already and it does not work, switch to the free radeon driver |

I remember trying the fglrx driver on Debian once. I will give it a try. Thanks!
