Dell Trackpad not recognized in Ubuntu 14.04 [duplicate]
Thank you in advance for your assistance.
I recently purchased a new laptop for use with Ubuntu 14.04 (Dell Inspiron i3542-8334BK), and am pleased to report that almost everything works out of the box.
The one exception is the touchpad. Ubuntu does not recognize it as a touchpad, but rather as a mouse. Note that Windows 7 (default installation on my laptop) DOES recognize the touchpad and has full support. Curiously enough, Debian Wheezy also supports my touchpad (running kernel version 3.2).
The largest problems with this are as follows:
- No scrolling
- The sensitivity of tap-to-click is outrageous. I normally disable tap-to-click due to general sensitivity problems in Trusty but here I can barely type a sentence without the touchpad accidentally clicking somewhere I don't want it to.
The relevant output from xinput list is:
Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ DLL0651:00 06CB:2985 id=11 [slave pointer (2)]
DLL0651:00 06CB:2985 is, of course the touchpad.
Thanks!
UPDATE: The previous Linux Kernel version did not provide support for my touchpad. A kernel update that happened today offered full hardware support.
Reinstall the driver:
sudo apt-get --purge autoremove xserver-xorg-input-synaptics && sudo apt-get install xserver-xorg-input-synaptics
Then reboot.
Installed kernel 3.13 and it worked. I have a dell inspiron 4452. Thanks!
