Mouse movement horizontally compressed on second display after suspend/resume

Bug Description

I'm using the proprietary fglrx display driver with Ubuntu 11-10 on a 64-bit system. I'm using two displays:

1. the laptop screen
2. an external monitor connected via HDMI

After suspend/resume, both displays still render correctly, and the mouse works properly on the first (laptop) display, but on the second display, its horizontal movement is compressed to about the left 20% of the screen. Disconnecting and reconnecting the second display does not help the mouse (though it continues to render correctly).

If I log out, so that the system reverts to mirror mode, then log back in, the mouse works correctly again.

I suspect that I just have to unload and reload a module around suspend/resume, but I'm not certain where to look.
