Using mouse get stuck on the floor

[rjuju]

Hi

I installed Amnesia Demo on Ubuntu 12.04. I use gnome, I have 2 screens, radeon card with ati fglrx drivers, and play in windowed mode.

When I play, if i move the mouse, the vision stay on the floor, turning around my feet. If I choose fullscreen, the mouse pointer isn't visible and I have to kill the process to quit.

Is there a way to resolve this issue ? I searched for similar issues but couldn't find any.

Thank you.

Do any other games exhibit this behavior? It almost sounds as if the input is being grabbed or affected by something else.. Usually when I see that it is because I'm using synergy from my Mac box to the linux box.. To fix I simply have to switch the keyboard+mouse directly to the linuxbox instead of going through synergy.

Another possibility is it could be unity messing something up. try disabling compiz and seeing if it works better.

Hi.
Thank you for your answer and sorry not to respond sooner.

I tried disabling xinerama and everything seems to go fine now
