Two cursors with two screens

[Just-trevor]

My monitor set up is pictured below. The one on the left is rotated left, the one on the right is normal. The link below is a screenshot of said set up. I drew a line where they separate if you can't tell.

For some reason, when I get close to the side of my big screen, a duplicate cursor shows up on the bottom of the other one. In the screenshot, the pretend cursor didn't show up, so I made a mark where it would be, and circled where the other one is. I put up the display manager for reference.

The fake cursor is right side up, but when I move the mouse up and down, it moves right and left, and vice versa - like it's overlapping the other screen and is sideways. When the smaller screen is not rotated, there is no problem.

So has anyone had something like this happen before, or any suggestions on how to fix it?

What's your graphics card and what does your `xrandr` look like?

Wow, an ATI card, I really wasn't expecting that.

I'm unable to reproduce the problem on my Laptop with Intel GFX,
but I'm sure you get much better 3D performance out of that ATI :D.

I wanted to see `xrandr` to see if your displays really do overlap
but this doesn't seem to be the case. Perhaps it's just an ATI bug.

I see.

Why so surprised by the ATI card? I'm surprised by your reaction.

Anyway more details if they are at all relevant: sometimes, when I boot up, the mouse is sideways and an inch or so away from where it 'actually' is, if you know what I mean.
Problem persists if both monitors are the same resolution and if the big monitor is sideways too, but not if the small one is upside-down. (I don't know why I thought that would make a difference, but what the heck.)


Basically this monitor is not only unnecessary, but non-functional. X|
