I found a solution for KDE and Kwin: You have to deactivate the Effect BLUR (german: Verwischen).
After this and activate Kwin everything works normal. But note, "Blur" was still working in the release before (Maverick). -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/774207 Title: [Natty Intel 945GME] No desktop effects (kwin 100% cpu) _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
