I've been struggling with what seems to be the same bug. Summary: When I log in, compiz and all my programs run ridiculously fast. Over the course of the next 30 hours (give or take), it gradually become sluggish and jerky. If I log out and log back in again, then it goes back to being fast.
Details: It's a nice, new, sexy computer. i7-2600K Sandy Bridges processors, 16GB RAM, SSD, GeForce GTX 570, current NVIDIA driver, dual screens with twinview, running Ubuntu 11.10 with Unity. When I log in, everything runs really, really fast with beautiful graphics. Gradually, things slow down (after maybe 6 hours). Programs which rely on OpenGL and normally use ~15%CPU will start using 100%CPU. Temp never exceeds 52 degrees F though, and RAM usage is low. Video memory usage stays low. No swap usage at all. My window switching becomes very choppy. To fix everything, all I have to do is log out and log back in. But 7 or 8 hours later, the same issues pop up. Reverting to Natty doesn't help at all. I first noticed this problem while using the graphics intensive program, VMD. But the problem is definitely not limited to that program. I even experience choppy window switching when I have no programs open. I've tried a billion things, but nothing has remedied the problem yet. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/888039 Title: Gradual degradation in desktop performance.
