I have a Dell Latitude E6500. I'd seen this problem with my 3-button IBM USB mouse, but it went away when I upgraded from Ubuntu 10.04 to 12.04. I have another external IBM USB mouse, this one with a wheel, and am still seeing the problem. So far I can temporarily stop the problem by un-plugging & re-plugging the mouse; I can also temporarily stop the problem with the command
xinput set-prop 13 "Device Enabled" 0 One thing to note is that the temporary fix works even if the device number DOES NOT match the AlpsPS/2 ALPS DualPoint TouchPad. I don't believe the issue is a conflict between the two devices for this reason. I think that the mouse-driver is getting into some crudded-up state that gets reset when I unplug/replug the device or if I run the above "xinput" command. My best guess is that Ubuntu has real drivers for some mice and uses a buggy default-driver for anything else, and 12.04 included a driver for my first mouse but not my second mouse. Can anyone at Ubuntu confirm this? Or give us a better explanation? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1363070 Title: USB Mouse cursor jumps and buttons get deactivated with two PS/2 devices connected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1363070/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
