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.
