description |
When the synaptics driver is called, it looks for the first touchpad that isn't already handled by synaptics. This is wrong in so many ways, especially when, for example, it grabs the magic trackpad that's driven by evdev when it was really looking for the normal trackpad on the laptop.
Synaptics must be stopped! |
Two touchpad devices A and B
X enumerates A before B
They both have a /dev/input/event* node and a /dev/input/mouse* node
I set up xorg.conf to use evdev for A
A gets handled by evdev
B's /dev/input/mouse* node gets probed by synaptics
it doesn't match /dev/input/event* in the synaptics probe function, so synaptics runs the eventcomm AutoDevProbe callback
the AutoDevProbe callback finds the first evdev node that isn't grabbed by synaptics already
in this case, it finds A and grabs it |

Freeze Exception Information:
The solution is to match the synaptics input module only for /dev/input/event* nodes. For the purposes of Ubuntu, this bug may cause the Magic Trackpad to be grabbed by the synaptics driver instead of evdev. When this occurs, gestures will not work. |
