Comment 248 for bug 41301

I also have this bug and would be interested in helping isolate it or in testing patches.

distro: Ubuntu 12.04 or Debian wheezy
desktop: Unity or Gnome 3
mouse: Cyborg R.A.T. 7
video: GeForce GTX 670

Observed behavior is that the mouse stops working on first login after I have at least two windows up. If I close those windows (^D or the like) and log out (effectively restarting X) the problem does not return until my next reboot. I have not experimented with the other triggering mechanisms yet (unplugging and re-plugging mouse, for example), but will be happy to try whatever.
