Public bug reported:

After my update today the mouse pointer clicks 1" to the right of its displayed position on my left display.
Currently center and right displays are 1920x1080 and the left display is 1280x1024

This worked 1 week ago.

Ubuntu 11.04 has been a disaster for multiple display. Multiple displays
worked well at the end of 10.10. Ubuntu props the Ubuntu Unity
interface, sprung from netbooks, which is a device category that has
been virtually dead since the iPad came out a year ago. Ubuntu Unity, in
my opinion, does not work well for multiple displays. With thunderbolt
launching, even laptops will have multiple external displays which
research proves to be about 30% more productive as opposed to a single
display. Another fact is that many computers will have multiple gpus
with multiple ports. Ubuntu therefore appears to be less in tune with
reality. It's over a year since a multiple display, multiple gpu
computers could use Ubuntu's main gui, or the composite effects offered
by hardware for years. Still, in this crippled mode, direct-gpu apps
draw squares on the wrong display all over the place and also tricks
regular apps to draw in rectangles of other apps. Ubuntu is worse off
now than a year ago.
