Default Alps touchpad problems

I am trying to get a laptop touchpad working properly with arch fully
up to date as of today. The machine is a recent Dell Vostro and has an
Alps touchpad. I can't get vertical scrolling to work in KDE, and the
mouse cursor occasionally moves erratically.

I have seen previous posts some time back recommending installing the
psmouse-alps package from AUR, and indeed it would appear that the 3.3
kernel may have a working psmouse module. However for the moment with
kernel 3.2.5 the touchpad is detected as P/S 2 Generic - instead of
the correct detection.

I have tried installing psmouse-alps and rebooting but it made no
difference so I uninstalled it again.

the Xorg log has:

[ 16.850] (II) config/udev: Adding input device PS/2 Generic Mouse (/dev/inpu
t/event8)

Does anyone have current experience with this issue and know the best

Default Alps touchpad problems

I had similar problem with a Dell Inspiron n5110, Alps touchpad. I bought
it last october, and by then this psmouse-alps package didn't exist, so I
got vertical scrolling to work using this module instead:

http://aur.archlinux.org/packages.php?ID=51343

But now I'm using kernel 3.1.8 and psmouse-alps package, and everything is
perfect. I've been holding the linux package from upgrading until kernel
3.3 is on core.

Default Alps touchpad problems

Hi Mike,

I have a Latitude E5520, and I suspect we have the same touchpad.

This is the Kernel bug you'll be interested in:
https://bugzilla.kernel.org/show_bug.cgi?id=14660

This is the patch I've been using to add support for my touchpad to the kernel
for the past few releases:
http://giddie.homeip.net/alps.patch

If you want it, here is a pre-built 64-bit kernel module:
http://giddie.homeip.net/psmouse.ko

You can keep it anywhere you want, and just "rmmod psmouse", and "insmod
psmouse.ko". I'm pretty sure this will do the trick for you.

Paul

OK thanks for the reply - I have not tried the psmouse-elantech
package from AUR but it might be worth trying it. However I am
currently using kernel 3.2.5 and there is no sign of improvement in
the touchpad behaviour. I was thinking of trying to compile the
psmouse.ko module and manually inserting it but I guess it would
likely do no more than building and installing the above package. I
suppose that once the reverse engineered module was taken up in the
upstream kernel for 3.3 then no further development or support
happened for the package to use in the pre-3.3 kernels though it the
meantime it is a little frustrating having to wait a month or two
until 3.3 is released!

Thanks Paul - I will certainly give your pre-built module a shot later
today.... and will post back to say if it works for me....

Paul - I did copy your file and loaded the module but it failed to
work - in fact it even stopped the touchpad cursor movement
altogether!

I returned to the psmouse-elantech package from AUR, built the package
and then installed it with pacman -U - and hey presto it gives the
correct behaviour in terms of touchpad tapping, as well as vertical
scrolling - it will need to be rebuilt each time there is a new kernel
until kernel version 3.3 is released but at least I now have a working
touchpad on the laptop so I can live with the small inconvenience of
rebuilding the module periodically in the interim.

Thanks for the input.

You could, just like i'm doing, hold kernel upgrades so you don't need to
rebuild the package every time... Just a suggestion

You can put the module to
/lib/modules/extramodules-3.2-ARCH/ and then use it will all 3.2 versions.

But it is clearly easier to ignore potentially vital updates.

Thank you - that is useful and I was not aware of that.
