Comment 14 for bug 374459

Created an attachment (id=25905)
Xorg full configuration.

Overview:
On the acer aspire xxxx, there is a new button next to the touchpad. If you press it, the touchpad is switched off, and the button's LED is switched on. After that, you cannot switch the touchpad on again.

i.e.: There is no touchpad switch on FN+F5 anymore. It has moved.

Steps to Reproduce:
(1) Press the button - the touchpad is off, as expected
(2) Press the button again, so the button's LED is off
(3) Repeat as often as you like.

Actual Results:
Touchpad is still switched off.

Expected Results:
Touchpad switched on.

Build Date & Platform:
Ubuntu 9.04 amd64

Additional Builds and Platforms:
Not really sure. I didn't test it on Vista, I removed it directly after buying. But it should work - explanation follows.

Additional Information:
Ok, now it gets a little complicated, or lets say, wired. "modprobe -r psmouse; modprobe psmouse" actually fixes it.
If it is on and you run this command, the touchpad will work.
If it is off and you run this command, the touchpad is still switched off, but - tada - can be switched on. But if you switch it off again afterwards, the bug occurs again.

Conclusion:
Switching on/off works until you switch it off for the first time.

Logs:
* dmesg - no output
* /var/log/messages - as above
