Fix broken left click on Linux

At home, I run a debian Squeeze on my 2008 macbook.

Lately, I had an issue: when my computer woke up after a sleep period, the left click of my mouse did not work anymore.
I had to restart my X server to recover the left click.

Actually, there is some conflict between my macbook native mouse and my USB mouse.

Fortunately, in Debian (and in other distros too), there is a tool called xinput which is used to configure X window input devices.

First, list the devices available for my macbook:

$ xinput --list
⎡ Virtual core pointer                          id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer (2)]
⎜   ↳ Microsoft Microsoft Notebook/Mobile Optical Mouse 2.0     id=10  [slave  pointer  (2)]
⎜   ↳ appletouch                                id=12   [slave  pointer (2)]
⎜   ↳ Macintosh mouse button emulation          id=14   [slave  pointer (2)]
⎣ Virtual core keyboard                         id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ↳ Power Button                              id=6    [slave  keyboard (3)]
    ↳ Video Bus                                 id=7    [slave  keyboard (3)]
    ↳ Power Button                              id=8    [slave  keyboard (3)]
    ↳ Sleep Button                              id=9    [slave  keyboard (3)]
    ↳ Apple Computer Apple Internal Keyboard / Trackpad id=11   [slave keyboard (3)]
    ↳ Apple Computer Apple Internal Keyboard / Trackpad id=13   [slave keyboard (3)]

As you can see, I have 2 mouses on my macbook:

  1. the native one: appletouch id=12
  2. the USB one:Microsoft Microsoft Notebook/Mobile Optical Mouse 2.0 id=10

To avoid any conflict between both mouses, I simply disable the native mouse, since I don’t use it.
Simply run:

$ xinput --set-prop 12 "Device Enabled" 0

Which means that I disabled the mouse with the id 12.

Don’t forget to update your xinitrc or your autostart.sh, if you’re using openbox like me.
