Samsung QX410-j01 Touchpad is not working

Question

I have been using Ubuntu on a Samsung QX410-j01 laptop for ~2 years (mostly v11.04). Yesterday, I upgraded to 11.10 and eventually to 12.04. Now, only the left click on the touchpad works. I cannot use right click. I cannot drag or resize any windows.

I would appreciate any help.

I tried to use synclient. It did not change. Here are the current settings:

Answer 1

The problem is solved.

I followed these instructions.

Since some part of the touchpad was working, I only performed the following steps:

1. wget http://people.canonical.com/~cndougla/enable-clickpad.sh
2. chmod a+x enable-clickpad.sh
3. ./enable-clickpad.sh <device name|device id>

Answer 2

I have the exact same model laptop with Elantech touchpad. I don't think this really worked on 11.04; it was recognized as a PS/2 mouse and as I recall it was too sensitive and the cursor was flying around all the time.

Starting with 11.10, the kernel has support for the Elantech touchpad. It may work a bit differently than you're used to, but since it's recognized as a touchpad now, it can be configured with the synclient utility.

You can for instance open a terminal (ctrl-alt-t) and run:

synclient RBCornerButton 3

This will generate a right click when you tap the bottom right corner of the touchpad. I also use:

synclient Tapbutton2 3

This generates a right click when you tap with two fingers anywhere in the pad.

I also suggest you enable palm detection:

synclient PalmDetect=1
synclient PalmMinZ=100
synclient PalmMinWidth=8

You can tweak the PalmMinZ and PalmMinWidth to your liking, until the driver correctly ignores accidental contact

You can read about available settings by issuing this command:

man synaptics

Answer 3

Right now, I'm using Ubuntu 12.10 on a Samsung QX410.

Here is my conf to get my touchpad working the same on Windows

synclient Clickpad=1
synclient HorizEdgeScroll=1
synclient HorizTwoFingerScroll=1
synclient VertTwoFingerScroll=1
synclient RightButtonAreaLeft=1500
synclient RightButtonAreaRight=2846
synclient RightButtonAreaTop=1400
synclient RightButtonAreaBottom=1771

Hope this helps.
