Same issue here. I've been able to determine that I'm seeing this issue ONLY when two pointer devices are enabled at once. Let me be clear on that point, I'm talking about two different "InputDevice" sections, I have my track point and USB mouse defined separately. (I am not using the all-in-one "/dev/input/mice" device since each device is configured differently). Based on the configuration, and which pointer is enabled, I've seen the "out of control auto-clicking" behavior that others have described. Normally, one of the pointer devices works fine and then the other has massive clicking issues. By disabling one of the devices I can make the other device work properly. This can be done either by switching (1) changing the xorg.conf file (as other have mentioned) or (2) using xsetpointer during and X session.
I'm also seeing this bug with just one device connected, but enabled twice... (Yes, very werid).. Take a look at my list of pointers in the output below. Just so no one asks, I only have one InputDevice section for "TpMouse" in my xorg.conf; and "TpMouse" is only referenced once in ServerLayout. However, I do have a device named "UsbMouse" which is missing from list, but it wasn't plugged in when I started X so that may explain it. xsetpointer -l 0: "Virtual core keyboard" [XKeyboard] 1: "Virtual core pointer" [XPointer] 2: "TpMouse" [XExtensionPointer] 3: "TpMouse" [XExtensionPointer] 4: "Generic Keyboard" [XExtensionKeyboard Does anyone else show the same device twice in their output from "xsetpointer -l"? If I run "xsetpoint -c TpMouse" to disable the device, then my mouse works fine. If I re-enable it with "xsetpointer +c TpMouse", I start to see the odd mouse behavior again. Any ideas on how I have the same device loaded twice? I would think that device "Identifier"s would have to be unique, but according to Xorg.0.log, the TpMouse device was setup twice. Here is a small section of the log (the entire log is attached where you can see that the "TpMouse" device is setup twice and then enabled twice) (II) XINPUT: Adding extended input device "TpMouse" (type: MOUSE) (II) evaluating device (TpMouse) (II) XINPUT: Adding extended input device "TpMouse" (type: MOUSE) (II) evaluating device (Generic Keyboard) (II) XINPUT: Adding extended input device "Generic Keyboard" (type: KEYBOARD) (II) TpMouse: ps2EnableDataReporting: succeeded (II) TpMouse: ps2EnableDataReporting: succeeded ** Attachment added: "Xorg.0.log" http://launchpadlibrarian.net/13553049/Xorg.0.log -- [Hardy] External mouse on laptop will only double-click https://bugs.launchpad.net/bugs/188351 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
