Xinerama has a bug/behaviour in 10.4 Lucid that wasn't there in 9.10. http://ubuntuforums.org/showthread.php?p=9417686 Under 10.4 Lucid using Xinerama with two monitors (Left,Middle) on an ATI card (FireMV 2250 with "radeon" driver) and the third monitor (Right) on an nVidia card (G86 GeForce 8300 GS with "nv" driver or "nvidia" driver). I did not have this problem under 9.10 Karmic. With Xinerama turned off, the mouse moves perfectly between all three monitors - the two monitors on the ATI card (Left,Middle) and the single monitor on the nVidia card (Right). Unfortunately, it splits my desktop into two DISPLAYs (ATI and nVidia) and so I can't move windows between the two. Under 10.4, with Xinerama on, Left and Middle start out showing the same content. (This looks like mirror mode, but isn't.) Starting on Left, I can move the mouse to the right, and it crosses both Left and Middle simultaneously until it reaches the right side of both. Then, the mouse leaves Left and we discover that Middle is actually a scrolling double-width screen with only a single width showing - as I move against the right edge of Middle, the mouse causes Middle to scroll/pan, until both virtual Middle screens have been crossed, then Middle stops scrolling and the mouse moves onto the Right monitor. At this point, with the mouse all the way to the right, I have three monitors showing three different 1600x1200 parts of the full 4800x1200 Xinerama desktop. Moving the mouse back toward the left from the Right monitor, the mouse crosses Right, leaves Right and moves onto the right edge of Middle, and crosses left across Middle, then when the mouse hits the left side of Middle, the mouse also appears on the right side of Left, and as I continue to move the mouse left, the mouse crosses Left and Middle scrolls/pans until it is showing exactly the same content as Left. At this point, with the mouse all the way to the left, I have Left and Middle mirroring each other (wrong) both showing the leftmost 1600x1200 of the full 4800x1200 Xinerama desktop and Right continues to show the rightmost 1600x1200. The middle 1600x1200 is no longer visible on Middle. I need to find out how to tell Middle not to scroll and to show only the right side of its double-size viewport. This didn't happen under 9.10.
