Description: Ubuntu 10.04 LTS
Release: 10.04

I am using a GeForce 8800GT with dual monitors:
First Monitor: Samsung SyncMaster 1680x1050
Second Monitor: LG L196WTQ 1440x900
Driver: NVIDIA accelerated graphics driver (version current) [Recommended]

When I open NVIDIA X Server Settings, it shows my Samsung SyncMaster screen on the left and the LG monitor on the right, which is backwards in their position on my desk.
So I first set the configuration to "Separate X screen" for both monitors, then "Enable Xinerama" and "Save to X Configuration File" and reboot.
At this point, it works fine and I do not experience the issue mentioned in this topic.

Next I take and drag the Samsung monitor to the right of the LG monitor as shown in the attached image and set it's X Screen position to "Right of".
It automatically sets the Position of the LG screen to "Absolute +0+0".
I save the settings and then reboot. Now they are displayed correctly, but the mouse pointer will not go very far onto the second screen and it glitches on the second screen as experienced by others above. It works fine on the Samsung screen though.

I've tried switching to the other Nividia driver listed under my hardware drivers titled: NVIDIA accelerated graphics driver (version 173) and tried rebooting and no luck, exact same behavior.
I couldn't find a working solution for this issue and when I went to report the bug, I was going to report it on the nvidia-common package, but found this bug report already.

Issues with the Nvidia driver and Xorg have plagued three versions of Ubuntu for me starting with 9.04 and now 10.04, although I don't get the random driver crashes during boot in 10.04 as I did with 9.10, which means it has improved.

Here's the contents of my /etc/X11/xorg.conf file if that offers any help: http://pastebin.com/edzrdNvc
