Mouse pointer off on different-resolution external display

[Harald Rudell]

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.

This worked after a full power off rather than reset, which I think is required for Quadro NVS to figure out new monitors. I run my 96 dpi monitors using gnome 132 dpi to get larger text

I have since gone back to three identical monitors, so the problem is not longer affecting me

Hey harald-rudell,

You filed this bug report against natty, but I see it's still open and
doesn't appear to have much activity recently. So, now that oneiric
is released and stable, this may be a good point for you to upgrade
and re-test if this issue is still present there.

If it's solved in the new release and you think it's worth backporting
the fix, please indicate that. Or if having the fix in the new release
is good enough, feel free to close out the bug (or let us know and we'll
close it.)

If it's not solved, leave the bug report open. I can't promise we'll
get to it (we get way more bugs filed than we can usually get to), but
your testing and feedback can help out if and when we do.

[bugbot (bugbot)]

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.
