I can confirm this bug, however as some elements differ I'm not sure it is the same. I have a Sony Vaio VGN-FS415S laptop with a GeForce GO 6400 inside. I also have drivers version 169.12 and I'm also using TwinView, but I installed them with jockey (formerly restricted-drivers-manager).
With kernel 2.6.24-12-generic compiz was running fine. With 2.6.24-15-generic running compiz makes the desktop unusable. ** Changed in: compiz (Ubuntu) Status: New => Confirmed -- [Hardy] Compiz Fusion very slow https://bugs.launchpad.net/bugs/213162 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
