Bug Description

I upgraded my Ubuntu 11.04 to Ubuntu 11.10 Alpha 2 on my Lenovo Laptop...

After this, the laptop keyboard and touchpad simply don't work.

If i'm using an USB keyboard/mouse it work.. but if i reboot the laptop they don't work, i have to unplug and plug them again.

I didn't know what package is this about, since I don't see any error message.

Tell me what files/logs do you guys need to find this problem and I'll help.

Thanks in advance

Thanks for your report.

Do you know after which package update the problem started ?
Could you please attach the file /var/log/apt/history.log

Thanks in advance

Looks like the kernel detects the devices, the devices get registered with the input subsystem, and udev is getting notified about the input devices. So as far as I can see both the kernel and udev are doing the right thing as far as device detection goes. Let's check whether or not the laptop keyboard and touchpad really are working.

Thiago, can you please try the following? First run 'sudo apt-get install input-utils'. After that installs, run 'sudo lsinput' and look in the output for devices named "AT Translated Set 2 keyboard", "AlpsPS/2 ALPS GlidePoint", and "PS/2 Mouse". The top of each section will read "/dev/input/event" followed by a number. Take that number for each device and run 'sudo input-events <number>' with the number for a given device. Then either press keys on the keyboard for the keyboard device or move your finger on the trackpad for the touchpad/mouse devices.

What you should see when you run input-events is some output spewing on the screen each time you press a key or move your finger on the trackpad. If you don't see the output, or if the devices aren't present in lsinput, we're probably looking at a kernel problem. If the devices are present and you get output from input-events, the problem is at a higher level.

Thanks!

Here's the result:

4 - "AT Translated Set 2 keyboard" -> output OK (response to every key press)

10 - "PS/2 Mouse" -> no output

11 - "AlpsPS/2 ALPS GlidePoint" -> output OK (response to evenry touch and click on the touchpad)

Can I just chip in and mention that if I use 'xinput test' then the PS/2 Mouse entry doesn't give any events for the touchpad but does for the trackpoint. The SyPS/2 Synaptics Touchpad does though. For input-events i get no events from either device.

Hope this is useful info, even if it comes from different hardware.

Brendan: Come to mention it I can't get my touchpad events via input-events either unless I switch to a VT. I'm assuming this is because X is using EVIOCGRAB on the input device. But in this case it looks like the kernel is generating the input events.

Thiago: Next let's run 'xinput --list' and see if the devices are listed there. If the devices are listed, run 'xinput --test <id>' with the ids for the AT keyaboard and touchpad devices. Please post back here whether they are listed, and if so whether or not they generate events.

I've the same problem. I got it with an normal update at the 22th of Nov. So now since two days the keyboard and touchpad of my laptop don't work. The keyboard as well as the touchpad are listed at the output of "xinput --list" but I didn't get any reaction with "xinput --test".

First I tought it's maybe because of the update of the linux kernal. But starting with the old version don't bring any help. The strange thing is that everything is working fine when I start Ubuntu in recoverymode. Another thing is that the FN + Display combination works as well but no other key.
