Comment 54 for bug 570151

My Setup:

Onboard:
Integrated Graphics Chipset: Intel(R) 965G (VGA)
PCI Dual head (one VGA and one DVI):
NVIDIA GPU GeForce 6600 (NV43) at PCI:1:0:0 (GPU-0)

Three monitors of 3 different sizes (what I could scrounge up at work)

Left Monitor is using the onboard Intel
Middle Monitor is using the VGA on the GeForce
Right Monitor is using the DVI with a VGA converter on the GeForce

Section "ServerLayout"
        Identifier "Manual Config"
        Screen 0 "Screen-Optiquest" 1280 0
        Screen 1 "Screen-ViewSonic" 2960 180
        Screen 2 "Screen-Acer" 0 60
        InputDevice "Mouse0" "CorePointer"
        InputDevice "Keyboard0" "CoreKeyboard"
        Option "Xinerama" "true"
EndSection

The reason for my crazy layout:
I want only the middle monitor to have the panel/toolbar, which is why I'm using Xinerama and Screen 0 is my middle monitor.
I'm not using Twinview, because my resolutions are different on each monitor.

I have found that the mouse getting stuck usually happens when I am waiting for a Window to render. This is mostly when a program is running in Wine or if I am waiting for Firefox to load a video or a flash based picture gallery AND when I move my mouse across screens. If I wait until the window is fully rendered to move my mouse, the mouse does not get stuck. I hope this helps.

I wish this issue would get the attention it needs. 54 comments, 24 (known) people affected, a Google search turns up many other forum posts with the same unresolved issue, multiple affected OSes, absolutely no workaround...this list goes on. This is a very frustrating issue. The reason for having multiple monitors is because it helps us be more productive. It defeats the purpose of being productive when my system locks up 2, 3, 4+ times a day, losing all my unsaved changes, killing any running processes, and having to wait for my system to reboot...just my 2 cents.
