Need input-hotplug - If xorg.conf is removed, Synaptics touchpad not detected

Bug #112664 reported by Irios
Affects Status Importance Assigned to Milestone
xorg (Ubuntu)

Bug Description

Binary package hint: xorg

Running feisty on a laptop with a Synaptics touchpad. After installation of feisty, everything works fine.

The touchpad has a 4-way scroll button in the middle of the two standard buttons. Tapping on the touchpad is interpreted as a click or double click. Double-tap-and-hold-and-drag works as click-and-drag.

If I remove /etc/X11/xorg.conf, everything keeps on running OK, (in fact it *seems* faster -- can it be?) but the touchpad loses its tap-and-drag and scroll-key abilities, and acts as a simple mouse, just as if there were no Synaptics entry in xorg.conf. In fact, Xorg.0.log has these lines:

(WW) The core pointer device wasn't specified explicitly in the layout.
 Using the default mouse configuration.

If I restore xorg.conf, everything goes back to normal.

I know this is not an even slightly severe bug, but it seems to be a bug in hardware detection nonetheless, so I though I might as well report it.

This should work once we switch to using input-hotplug in hardy.

Is this still due to happen? If it's happened already, then it's not working correctly.

I have a synaptic touchpad, and the only way I was able to get it working is for me to edit my xorg file. Naturally, without an advanced degree in xorg.conf logic I've broken a number of other things.

Once it is working I get an extra tab in system -> preferences -> mouse called Touchpad, which seems to indicate that my touchpad is now detected correctly. Well, not detected, but you understand.

No, Hardy will not use input-hotplug by default. We will evaluate it again for Intrepid.
