Touchpad of Dell E4200 not working

ItsJustLoco · 01-19-2009, 12:57 PM

Hi,

I googled some time for a solution to my problem, but didn't find anything.

I bought a Dell Latitude E4200 before some time and used it since then with slackware. The touchpad is working, but the scrolling isn't.

I tried to configure my xorg.conf but without success.
It seems that the touchpad isn't recognized.

Output of:

Does anybody have an idea how I can make scrolling working?

Thanks in advance

how does the Touchpad section from your xorg.conf looks like?

You can probably find some good threads on this forum about it by searching for 'synaptics'.

But from my own notes I know you need at least the following:

In /etc/modprobe.d/psmouse comment out...

Code:

#options psmouse proto=imps

NOTE: You might also try...
options psmouse proto=auto
(Not a 'supported' option but it works on one of my boxes!)

Then reload the module by...

Code:

modprobe -r psmouse
modprobe psmouse

You can do the same thing effectively by passing it the 'auto' parameter at boot time by adding in lilo.conf...

Code:

psmouse.proto=auto

You might also find it necessary to disable USB KB/Mouse legacy emulation in your system's CMOS.

Then after reloading the module or reboot for CMOS change, it should work with the synaptics driver loaded in your xorg.conf.
