I believe I know the source of this problem. I've also filed a bug against "nvidia-settings" as the problem is likely related to another problem with "nvidia-settings"
see: https://bugs.launchpad.net/ubuntu/+source/nvidia- settings/+bug/1116588 gnome-control-center's "Wacom Graphics Tablet" settings seem to rely on the nvidia drivers' notion of the screen layout which is incorrect causing incorrect "map to monitor" behavior. You can see the conflict in the attached screenshot comparing nvidia- settings notion to the system's display configuration tool. ** Attachment added: "example of display layout notion conflict" https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/1003913/+attachment/3516259/+files/nvidia-rotation_problem_with_system_tool.png -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/1003913 Title: Wacom Graphics Tablet "Map To Monitor" setting doesn't work with Twinview Status in “gnome-control-center” package in Ubuntu: Confirmed Bug description: While it's great to see some better built-in support for Wacom graphics tables in 12.04, the "Map To Monitor" option does not work with nVidia Twinview enabled. I have the proprietary drivers installed with two1920x1080 monitors that are presented as a single 3840x1080 desktop. When Map To Monitor is clicked, onlly a screen is displayed, and the graphics tablet maps to the entire desktop. The graphics tablet is a Wacom Bamboo. 1) The release of Ubuntu you are using Description: Ubuntu 12.04 LTS 2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center Not sure which package this applies to. My system is fully up to date as of today. 3) What you expected to happen It should be possible to map the tablet to a single monitor. 4) What happened instead The tablet is mapped to the entire desktop, rendering it useless for anything serious.
