This also occurs on ATI. Running 4 screens on 2 cards. Interestingly this only happens going right > left on the top 2 screens (same card). If I move the mouse slowly accross the gap, no jump. Anything approaching "normal" travel speed and the cursor jumps all the way to the left side. No vertical change.
xorg.conf attached. ** Attachment added: "xorg.conf" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/1035555/+attachment/3530635/+files/xorg.conf -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1035555 Title: dual monitor cursor jumps across screen when crossing display edge Status in “xserver-xorg-video-nouveau” package in Ubuntu: Confirmed Bug description: 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.)
