Synaptics not working on Slackware 12.2 Custom Kernel

[SOLVED]: http://www.linuxquestions.org/questi...kernel-706845/.
I custom-built my kernel and installed the synaptics drivers. I am on a Dell XPS m1530. My touchpad works fine in kde; it clicks and moves. I cannot get scrolling by moving my finger along the side of the touchpad to work. My understanding is that for this I need to have the synaptics driver working and enabled. I do not know the device to which the touchpad is connected, and /dev/psaux does not exist. I am loading the synaptics module in xorg and I left the mouse device as the default /dev/mouse. Thank you.
Relevant part of xorg:

Code:

  Identifier    "Mouse1"

    Driver        "synaptics"

    Option        "Device" "/dev/mouse"

    Option          "VertEdgeScroll"  "true"

EndSection

EDIT: Please refer below for further logs and information.

Look in /dev/input for other things to try setting Device to.

Also, try using the "imps2" driver. It's worked for me on laptops with touchpads where Synaptics has failed.

I rebuilt a later kernel (v. 2.6.28.7) with synaptics and evdev built in and psmouse as a module. I then installed the synaptics driver from source. I believe the problem is relatively low-level as my touchpad seems to not be detected as a synaptics one:

Code:

I know it is a synaptics-capable touchpad as it works as such in Ubuntu. How do I solve this? Thanks.

My guess is you have a configuration problem in your custom kernel.

Did you try a stock Slackware kernel, as the Synaptic driver is included in all ?

Code:

bash-3.1$ grep SYNAPTIC /boot/config*

config:CONFIG_MOUSE_PS2_SYNAPTICS=y

config-generic-2.6.27.7:CONFIG_MOUSE_PS2_SYNAPTICS=y

config-generic-smp-2.6.27.7-smp:CONFIG_MOUSE_PS2_SYNAPTICS=y

config-huge-2.6.27.7:CONFIG_MOUSE_PS2_SYNAPTICS=y

config-huge-smp-2.6.27.7-smp:CONFIG_MOUSE_PS2_SYNAPTICS=y

bash-3.1$

I have not yet tried a stock kernel. Here is some interesting/useful output (config-2.6.28.7 is the one I used for my kernel):

Code:

redscare@redscare-laptop:~$ grep SYNAPTIC /boot/config-2.6.28.7

CONFIG_MOUSE_PS2_SYNAPTICS=y

redscare@redscare-laptop:~$ grep MOUSE /boot/config-2.6.28.7

CONFIG_MOUSE_PS2_ALPS=y

CONFIG_MOUSE_PS2_LOGIPS2PP=y

CONFIG_MOUSE_PS2_SYNAPTICS=y

CONFIG_MOUSE_PS2_LIFEBOOK=y

CONFIG_MOUSE_PS2_TRACKPOINT=y

# CONFIG_MOUSE_PS2_ELANTECH is not set

# CONFIG_MOUSE_VSXXXAA is not set

# CONFIG_USB_IDMOUSE is not set

Apparently I managed to break the stock kernels, I get no internet and my mouse completely breaks (doesn't move). Renaming those module folders was a bad idea. Installing the synaptics driver from source even though I have it included in the kernel shouldn't break anything, right? My Xorg.0.log might be helpful, it suggests /dev/input/event* is the culprit:

Code:

redscare@redscare-laptop:/var/log$ cat Xorg.0.log (I only show relevant stuff)

Thank you.

EDIT: This is an XPS M1530 laptop, if that in any way helps, and I run with kernel boot option i8042.nomux=1.

EDIT: I forgot to mention that I recompiled the kernel with support for /dev/psaux and now use that as my device.
