Description jcl darkc 2012-11-10 15:29:55 CET

Description of problem:

I have a dell Latitude laptop E6430 and scrolling with touchpad does not work. It's a known bug by many distributions:

https://bugzilla.redhat.com/show_bug.cgi?id=812111

Some fixes exist :
http://resalxh.wordpress.com/2012/09/18/ubuntu-12-04-lts-x64-the-next-step-getting-touchpad-working/

 Fix consist to recompile a patched version of psmouse.c in order to get a new psmouse.ko module. BUT the problem with mageia2, and probably with cauldron also, is that psmouse driver is not compiled as a kernel module but is included directly into the kernel. Then, if we try to apply the patch, no psmouse.ko is generated but a psmouse.o which is not usable.



Version-Release number of selected component (if applicable):
kernel 3.3.8-desktop-2.mga2

Comment 2 jcl darkc 2013-05-09 15:33:50 CEST

I reopened the bug report for mga3

I can understand that mga team developpers does not want to work on this specific problem, although it affects a lot of people working with an alps touchpad. 

At least, a solution would be to modify the way how MGA kernels are compiled. 

Mga kernels are configured to have PS/2 mouse support built in, which prevent to apply the patch (http://www.dahetral.com/public-download) following this post (http://forums.debian.net/viewtopic.php?f=16&t=95940).

 To apply the above patch, PS/2 mouse support MUST BE configure as a kernel MODULE, not built in . This is the case in most of the distribution, why not in MGA ?

 Could you make this modification for MGA3 kernel, it's just a matter of :

CONFIG_MOUSE_PS2=m

instead of

CONFIG_MOUSE_PS2=y

 in the .config file of the kernel.

 THANKS in ADVANCE,

 JC

It's not just a matter of changing the option, but also making sure the module is included and loaded everywhere it needs (like during installation).

We wont switch PS2 to module (atleast not for mga2/3), however...

the upcoming 3.8.12-2 kernel will support your touchpad (and several others that now have support merged upstream)

 that's a great news really !!! And when this kernel is expected to be released ?

Comment 6 Sander Lepik 2013-05-10 21:24:56 CEST

This kernel should be in the mirrors now. Just run update.

It's already available and my ALPS touchpad is working now !!!!  Thanks A LOT !
You know that you'll make a bunch of happy people with this feature finally activated. Many thanks again. :)

My ALPS touchpad is not recognized as such by the latest Cauldron kernel. It is used in mouse mode which is annoying during typing. I had to rebuild psmouse as a module and then add the dkms driver from http://www.dahetral.com/public-download/alps-psmouse-dlkm-for-3-2-and-3-5/view

With that driver it is recognized and stuff like two finger scrolling is working.

My ALPS touchpad on my Acer 7520 is not fully working; the buttons appear to be working however the touch pad portion itself is not.  This is on Mageia 5 Beta 3.  Thanks, Greg.

If you're using GNOME, you should be aware that for some reason we ship GNOME with touchpad tap-to-click turned off.  This may also be true for GNOME-derived Desktops.  It works as shipped for KDE.
