This bug happens on my system as well. Everything worked fine in 10.10, and now the system freezes after 5-10 seconds when I log into a window manager that uses compositing (kwin, compiz, ...). Rebooting is the only option.
Using xorg-edgers doesn't solve the problem. Disabling ACPI doesn't solve the problem. There are no newer nVidia drivers available at the time of writing. Every 3D application I have tried so far works fine, from glxgears to the Phoronix test suite benchmarks. I am using an nVidia 560 Ti card. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/769911 Title: System freeze after login in 11.04 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
