It's definitely related to desktop effects, I am totally lockup-free without them, but will reliably freeze the instant I turn them on (alt- shift-f12).
However, I am also plagued by bug 342923 which makes performance pretty awful and with screen corruption. I wonder if these two bugs are related somehow. I was running KDE4.2 from the PPA packages on intrepid before jaunty, and there were no problems at all. The intel Xorg driver has my finger pointing at it. -- [i965] X freezes starting on April 3rd https://bugs.launchpad.net/bugs/359392 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
