** Description changed: Binary package hint: xorg The mouse makes random jumps of about 20 pixels while being moved. Its very much like using an optical mouse on too smooth a surface - but this is when using a thinkpad trackpoint device - no other pointing device plugged in. This happens after executing the following commands xrandr --fb 1920x1200 xrandr --output VGA1 --mode 1920x1200 xrandr --output LVDS1 --mode 1280x800 xrandr --output VGA1 --pos 0x0 xrandr --output LVDS1 --panning 1920x1200+0+0/1920x1200+0+0/0/0/0/0 (Specifically, after executing the last one). Its very difficult to pick accurately a place to click, so if I am trying to maximise or minimise a window for instance, sometimes it kills the window instead - and vice versa. It only starts when the xrand panning command is activated. However I have been desperate for this feature to be put back since it was removed in a past version of Ubuntu and I am loathe to ditch panning. An accurate description is this. Picking a point to click, lets say the 'file' dialogue in a window, I move the mouse towards this point. As I get close, the mouse starts 'vibrating' rapidly (at a guess about 10 jumps per second). When I stop moving the mouse, the pointer stays still. However the pointer might not be where I need it. I move the mouse one pixel (very carefully) towards where I want it to be, and it shoots about 20 pixels down and to the right. Move another pixel and it jumps back to the original position, etc. The result with slow mouse movement is a vibrating mouse pointer that you can not place anywhere. This only happens in certain parts of the screen, but which part randomly varies. If I go back to a part of the screen where the pointer was vibrating 2 mins ago, it might not be vibrating now. However it might be vibrating if I move it to a different part of the screen now. As I work, it gets in the way frequently, at least once a minute. It also happens when I am simply over the desktop, and not over any application buttons or similar. I have also filed a different bug which is related to panning and the mouse, which might be related, and which prevents the smaller window into a larger virtual screen scrolling to the edge of the screen sometimes. My setup is a lenovo x200 laptop which is brand new, but which I tried with windows 7 first without a problem. It has a dell 24 inch monitor plugged in and I use the 2 screens at the same time, with a 1920x1200 virtual screen, with the monitor displaying this resolution natively and the laptop with a 1280x800 screen displaying a 1280x800 window into the virtual screen. Obviously the laptop screen pans around inside the virtual screen. The laptop is running a clean 9.10 install which has been updated by the update manager. Before I execute the panning xrand command, the problem is not there. If anyone can suggest things to try I will be glad to try them.
