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. Notebook (incl. Picture): https://wiki.ubuntu.com/LaptopTestingTeam/AcerAspire5738 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.

You can get the number by looking at /proc/bus/input/devices. When the touchpad works,you should get the events as you use it. When the touchpad does not work, do you still see events?

I'm afraid not. I found out that my touchpad uses event9. But I get an error just when the events should be comming. > When the touchpad does not work, do you still see events? Same as above, so just one file.

You need to VT switch away and then run evtest from the tty. While X is running you'll get the device information but not the events.

TPbutton working, TPL off output: events 2.) TPbutton pressed. TPL on. output: none 3.) TPbutton pressed. TPL off. output: none 4.) TPbutton pressed. TPL on modprobe -r psmouse; modprobe psmouse output: events - on x the TP wouldn't work now 5.) TPbutton pressed. TPL off. output: events - on x the TP starts operating as the lock is gone 6.) TPbutton pressed. TPL on. output: none. 7.) TPbutton pressed. TPL off. modprobe... output: events 8.) TPbutton pressed. TPL on output: none Seems pretty much like a hardware lock to me, but why do I see events after reloading psmouse when the TP should be locked (#4)? On the other hand, if it were a software issue, why does it handle it correctly on step 4 to 5 in X? Hope I got all combinations. If you need more info, just tell me. Also, there is a full Xorg.0.log on launchpad. Regards and thanks for helping.

On a guess, I'd say that it's only a hardware lock for the LED, not for the touchpad itself. And the kernel doesn't (or can't?) query the state of the lock. And it seems the kernel may not get the "on" event, only the "off" event. Hence this weird sequence of events. Only guessing here though. Either way, there's nothing we can do in the X drivers until we get the right sequence of events.

Once this message is printed, does the touchpad work? unfortunately, the touchpad driver isn't very chatty and doesn't print much when the connection is lost.
