Feedback on the Dell Inspiron 15R

Asked by Koen on 2012-01-16

Although this laptop is certified for Ubuntu, the touchpad is not recognized as a touchpad but as a ps/2 mouse.
It works for moving the pointer and double click, but not for scrolling or other functions.

Hi,

Thanks for your feedback!

Which release of Ubuntu are you using?

The certified Inspiron 15R I have here has Ubuntu 11.10 installed and the touchpad is recognized as a Synaptics, all touchpad functionalities are usable (including 2-finger scroll).

The kernel detects the Synaptics touchpad like this:

[ 17.040700] psmouse serio1: synaptics: Touchpad model: 1, fw: 7.2, id: 0x1c0b1, caps: 0xd04733/0xa40000/0xa0000
[ 17.119849] input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio1/input/input8

And xinput --list also identifies it as a touchpad:

⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=12 [slave pointer (2)]

I've tested this issue with the Dell 15R (N5110) in our lab with 11.10 32-bit. The touchpad (ALPS) operates normally with scroll functionality. Seeing as how your hardware is operating differently could be one of two different issues, an out of date BIOS or different hardware that was not certified. Dell may have switched components making your system different then our certified hardware.

Hello,

I checked (via windows) that i have an alps touchpad.
Is there some way to extract more information from the system to search for a solution?
The new version of the alps driver (0.10) does not give a solution.

One possible solution that has worked on Lenovo models is the following:

rmmod psmouse
modprobe psmouse proto=bare
