[Bug 825548] Re: Touchpad cursor moves twice as fast horizontally after connecting an external monitor

 

apport information

** Tags added: apport-collected reproducible ubuntu

** Description changed:

- After connecting an external monitor, the touchpad starts moving much
- faster in the horizontal direction than in the vertical direction, as if
- the screen area had been stretched rather than extended to include the
- area of both monitors.  This is really disorienting, throws off muscle
- memory, makes it hard to move in the right diagonal direction, etc.
- Reproduced in both natty and oneiric.
