Synaptics touchpad doen't work anymore on Slack 12.0

Hi,

From what I've seen so far Slackware 12 is great! But...
I can't get my touchpad to work as it did in 11.0

I use the same instructions as I did in slack 11: http://gentoo-wiki.com/HARDWARE_Synaptics_Touchpad

I use the buildscript from slackbuilds.org to compile the driver from source.

I tried loading the evdev an psmouse kernel modules, but no effect

part from Xorg.0.log:

I'm clueless.

Ok, I found what was wrong.
In rc.modules, there's a section:

Code:

### Mouse support:
# PS/2 mouse support:
# The default in Slackware is to use proto=imps because that works with the
# most types of mice out of the box.  For example, using proto=any will
# completely break the mouse if you change consoles with several models of KVM
# switches.
if echo $SHORTREL | grep -qvw 2.4 ; then
  /sbin/modprobe psmouse proto=imps
fi

The problem is in the "proto=imps" part. Somehow, with that option, the kernel sees the touchpad as a ps2-mouse, not as a synaptics touchpad. I commented out that bit so the line becomes:

Code:

  /sbin/modprobe psmouse #proto=imps

Now the mouse does what I expect it to do in X.
And it still works perfectly with gpm.

If read the script well, this part shouldn't be executed anymore, because it was meant for the 2.4.x kernels (RIP). Or am I wrong about that?

So, my take on it is that this part of the script will not run if you have a 2.4 kernel.

you're right
silly me
