Need input hotplug - touchpad uses wrong driver

Bug Description

Binary package hint: xorg

I´m using Xubuntu 7.04. In the xorg.conf file the input device is set to a wacom tablet. The laptop I´m using has a synaptics touchpad. Since I manually changed the xorg.conf file to use the synaptics driver it works as it should, and accepts a gui for changing its settings (qsynaptics). I think the install should make use of this synaptics driver in the first place.

Thanks reporting this bug Thomas. The wacom tablet entries are hardcoded and included in every xorg.conf that ubuntu generates, but the failure to detect your touchpad is a real bug. Marking as medium priority, and will plan to look at this as part of the xserver 1.4 work.

(Fwiw, by the time Gutsy comes out this fall, Xorg will likely have a new autodetection capability for input devices like touchpads, so it is likely this bug will get resolved then.)

Same problem on Dell Inspiron 9100 touchpad. Edited xorg with the following and works like a charm (may want to change the MinSpeed and MaxSpeed to your liking):

Section "InputDevice"
 Identifier "Synaptics Touchpad"
 Driver "synaptics"
 Option "SendCoreEvents" "true"
 Option "Device" "/dev/psaux"
 Option "Protocol" "auto-dev"

On my Toshiba laptop, the synaptics touchpad module never got loaded in gutsy. I downloaded hardy alpha-1 yesterday, and it also doesn't autoconfigure the synaptics touchpad.
Can I help in any way to get this bug fixed?

Please try the released 8.04, which should notice that you have a laptop and adds the synaptics entry in the config.

Should be fixed by now, at least in Intrepid.
