[Jaunty] Trackpad not detected on a noname Intel laptop

[Marc Tardif]

I'm running Jaunty with the latest updates as of today and the mouse trackpad doesn't work on some noname Intel laptop. I'm not sure whether this is a problem with the hardware or with Jaunty yet, I will follow up on this bug shortly after testing with the live cd from a previous release.

ProblemType: Bug

Mouse works fine on a hardy 8.04.1 live cd, so this seems to be a regression.

Hi Marc,

Can you take a look at the following and attach the requested debug info.

Here is some more information from the DebuggingTouchpadDetection wiki page:

$ cd /var/lib/acpi-support/; grep '.' *-*

$ cat /proc/version_signature

I also tried installing the linux-restricted-modules package, just in case it might make a difference, but the mouse still doesn't work.

Seems like it is being recognized by the kernel:

$ grep -irn "elantech" dmesg.txt

Just curious what your xorg.conf looks like?

[Marc Tardif (cr3)]

The file /etc/X11/xorg.conf is empty.

I have the same problem

[Vicenç Juan Tomàs (vtomasr5)]

I tried with xserver-xorg-input-synaptics package of debian sid (v1.1.0-1) and the same happens.

I added this section in my xorg.conf:

Section "InputDevice"
    Identifier "Synaptics Touchpad"
    Driver "synaptics"
    Option "SendCoreEvents" "true"
    Option "Device" "/dev/psaux"
    Option "Protocol" "auto-dev"
    Option "HorizScrollDelta" "0"
    Option "SHMConfig" "true"
    Option "TapButton1" "0"
EndSection

[Vicenç Juan Tomàs (vtomasr5)]

Wow, The problem has been solved only! It works now!
This is very strange.

[Vicenç Juan Tomàs (vtomasr5)]

It's very strange. If I remove the battery from my laptop, the trackpad works!, however, if I plug it the battery trackpad doesn't work!

can anyone confirm this?

[Bryce Harrington (bryce)]

Hi Mark, the input subsystem has been pretty radically changed since this bug was reported last year; are you still having the same issue with it?

[Bryce Harrington (bryce)]

I'll go ahead and assume this is fixed now; you can reopen if it's still an issue (or better yet... file a new one using ubuntu-bug)
