[gentoo-user] Touchpad no longer working

[Michael J. Barillier]

The touchpad on my Acer laptop has stopped working in X after a recent
`emerge -uD world'.  Looking through emerge.log doesn't indicate
anything hardware-related.  The touchpad shows up in dmesg:

,----
| Synaptics Touchpad, model: 1, fw: 6.2, id: 0x12a0b1, caps: 0xa04713/0x204000
| input: SynPS/2 Synaptics TouchPad as /class/input/input5
`----

and in /proc/bus/input/devices:

,----
| I: Bus=0011 Vendor=0002 Product=0007 Version=12b1
| N: Name="SynPS/2 Synaptics TouchPad"
| P: Phys=isa0060/serio1/input0
| S: Sysfs=/class/input/input5
| U: Uniq=
| H: Handlers=mouse0 event5 
| B: EV=b
| B: KEY=6420 0 7000f 0 0 0 0 0 0 0 0
| B: ABS=11000003
`----

and /proc/config.gz says:

,----
| CONFIG_MOUSE_PS2_SYNAPTICS=y
`----

I'd seen references to cat-ing /dev/input/mouse0 and using the touchpad,
but when I do that no output is generated.  xorg.conf has:

,----
| Section "InputDevice"
|         Identifier "TouchPad"
|         Driver "synaptics"
|         Option "SendCoreEvents" "true"
|         Option "Protocol" "auto-dev"
|         Option "SHMConfig" "on"
| EndSection
| 
| Section "ServerLayout"
|         Identifier     "X.org Configured"
|         Screen      0  "Screen0" 0 0
|         InputDevice    "TouchPad" "CorePointer"
|         InputDevice    "Keyboard0" "CoreKeyboard"
| EndSection
`----

but the pointer still fails to move (x11-drivers/synaptics has been
emerged too).  Does anyone have any suggestions on where to look to
diagnose this issue?  I'm running out of ideas at this point.
