Public bug reported:

Binary package hint: xserver-xorg-input-evdev

Since upgrading to evdev 2.6.0, X crashes when starting and leaves all graphics & input in an unusable state.
Trying evdev from upstream X git works fine, only when using Ubuntu sources does X crash.

Backtrace from Xorg.0.log:

Much more information should be attached.

I could try applying the Ubuntu patches one by one to see which one
crashes X, if someone tells me how.
