Comment 1 for bug 248919

Some update for this bug.

       I found this issue happen only if I have a configured mouse
setting with /dev/input/mice device.
       If I change mouse device from /dev/input/mice to /dev/input/mouse1,
       the touchscreen dobule click won't happend.
       However, there are some side effects.
       1. I have to plug-in usb mouse before start-x. otherwise, the
mouse won't work.
       2. bluetooth mouse has similar issue with case 1. After
connect to bluetooth mouse, I have to re-start X to
make it works.
       3. the device node may change, any device name other than
mouse 1 in my config will make the device not work.
