Bug Description

I have 2 monitors on the system. The samsung is working as it should. The video7 has the resolution set at 1280*1024 at 75Hz. The V7 mouse does not stop at the top of the screen even though that is where the window stops. Give me an email address and I will send you a screen shot. The right hand screen which is a samsung 1920*1080 has it boundary stop at the top of the physical screen. Not so with the V7.

From your Xrandr info:
"""
…
DVI-I-2 connected 1280x1024+0+56 (0xa4) normal (normal left inverted right x axis y axis) 376mm x 301mm
…
"""

The 1280x1024 bit is the resolution it's using, and the +0+56 is the position the X server has been told to put it - which means the X server thinks its 56 pixels down from the top. That's where your mouse is ending up.

This doesn't appear to be a driver bug. Rather, it's a configuration issue. Try re-aligning the monitors in gnome-display-preferences - the snapping zone isn't very big, so it's quite easy to set up your displays not quite aligned like here.

Moving to gnome-control-center. This isn't an X bug, but it is annoying that it's so easy to set up a configuration that you didn't intend.

The bug description is not really a bug but indeed g-c-c could make it a bit harder to run into such configuration issues
