#1

I am using opensuse 13.1 gnome desktop in my dell vostro 2520 laptop.

In settings of my gnome desktop, i come to know that the touchpad of mine is not detected and hence scrolling down pages during and other stuff is really hard.

I need a solution to this. Can anyone help me???

Hi
What hardware;


dmesg | grep Touch

If synaptics is xf86-input-synaptics package installed,

It is enabled in the BIOS?

Hi
Looking around, it would appear you may have an ‘Alps’ touchpad, can you check if the module is present?


ls /lib/modules/`uname -r`/kernel/drivers/input/

dmesg | grep Alp

Might need to build the module if it’s not present…

gameport joystick misc sparse-keymap.ko
input-polldev.ko keyboard mouse tablet
joydev.ko matrix-keymap.ko serio touchscreen

this is what i got for the first command u had gave me

and i didn’t get anything for the second

thankyou malcolm

I would test this out by installing the “xinput” package. This is a great little program that shows you what is connected.

Type in:

xinput list

I have read that others have been successful using the “synaptiks” driver.
Start the Yast Software Management and installing the “synaptiks” package".

See: https://bugs.launchpad.net/ubuntu-certification/+bug/1046929

Restart your laptop and try it out.

#9

The OP’s hwinfo output shows that the device is not recognised as a touchpad, as the ‘synaptics’ Xorg driver doesn’t recognise it. A later Xorg/kernel version might provide the required support though. (BTW, it is the ‘xf86-input-synaptics’ that provides the touchpad Xorg driver)

#10

Agreed. This problem appears to be in every distro. One would think that Dell would provide a driver for it -NOT.
Hopefully, we may see this in kernel 4.2 or 4.3. I would encourage the OP to make a bug report with Bugzilla.

#11

I was just pointing out that it is not as simple as installing a package (the synaptics driver is included anyway). The OP is using openSUSE 13.1 - which uses kernel 3.11.x.y, so perhaps worth trying with latest openSUSE version and upgrade to latest stable kernel?

#12

Ah, that’s an issue I had with Linux Mint 17 and reason why I changed distro.

I never found a permanent solution but you can use this as a reference:

I recommend trying the modprobe “fix” and if it works, you could edit the boot script.

#13

No, that won’t work since ‘psmouse’ is built into openSUSE kernels, not as a separate module.

guys … guys… I am not getting a word u’re saying but upgrading to new opensuse 13.2 is not a good option for me. I am having a lot of stuff installed in it and i am working on it. Except this problem on touchpad my os is absolutely fantastic. So if u have any suggestions that can help me solve this problem permanently i would really appreciate it…Thank you…

Only my suggestion in post #9, but if you’re a new user this is probably not a trivial thing to to try.

Sometimes an upgrade is necessary to get the required hardware support. You could try testing via a Live version - that way there is no need to install for testing purposes.
