mouse jumps to one point over and over again in fullscreenapp

[Marc Brinkmann]

Binary package hint: xorg

In fullscreen apps like xmoto, supermaryo or openarena my mouse keeps jumping to one fixed point on my screen.
i can move it for 1 or 2 seconds, then it is back at its place.

When btrfs were availiable and working in an dailybuild after alpha2, i re-installed my system under x64.
Since then, this problem persists.

I already deactivated compiz and the nvidia-driver.
Nothing helps me.
In the german ubuntuusers jabber channel, we could not fix the the problem either.
On said, an external screen caused this problem for him, but i never had an external screen at this system.

Today one had the idea, that SDL might cause this misbehavior. But he could not replicate it under Lucid.

This is (the second try of) my very fist bugreport. I hope, i provided enough data, so that someone might be able to understand and fix the problem.

Thanks in advance

Hi,
  This sounds like 61105; can you uninstall the 'unclutter' package and see if it fixes it; if it does then please mark this as a duplicate of 61105.

(Unclutter got installed on early alpha releases and then removed when the chaos it caused was discovered).

Woooohooo, you are absolutely right.
i removed unclutter, rebooted and the Problem is gone.
Thank you very much.
Will try to mark my bug as duplicate now.

Best regards
Marc
