Public bug reported:
I recently updated my system to 12.04; it has two screens driven by an
NVidia GeForce 8400GS graphics card. Xinerama is enabled. When I move
the mouse left across screens, it jumps from left edge of one to left
edge of the other. It does not do this in the reverse direction. This
right-to-left behavior is really weird; left-to-right is okay.
More details:
* xorg.conf shows screen 0 is left, screen 1 is right, and Xinerama is enabled.
(See below.)
* Moving the mouse on the desktop from screen 1 to 0 (i.e., to the left), it
leaves the left edge of screen 1 and shows up on the left edge of screen 0; it
does not glide across screen 0 to get there... unless I move across the edge at
!very! slow speed; I can then pick up speed after crossing, and it behaves
normally. (Yes, speed sensitive.)
* It does not do this when moving right (screen 0 to screen 1). In that case,
it mouse glides across the desktop with no problem.
To add some confusion, running 'nvidia-settings', it talks about a single
screen and two displays.
* X Screen 0 shows dimensions 2960x1050, and displays Dell 2005FPW (DFP-0) and
Sharp LL-172C-B (CRT-1).
* GPU 0 shows:
- CRT-1 (Sharp) refresh rate (60.02 Hz), but no dimensions;
- DFP-0 (Dell) resolution 1680x1050 and refresh rate of 59.88 Hz, 'Full Force
GPU Scaling', GPU Scaling Method: 'Stretched'. (But it looks fine to me.)
