My E6430 came with 12.04 preinstalled and touchpad working with multitouch 2finger scrolling and also pinch-zoom. (I have the original ISO image for the factory settings if you're interested I can upload it.. 2.2 Gb it will take ages with my connection.. so ask only if you really need it.. the solution for trackpad is in this post.. so maybe you don't need the iso really)
Now I switched to Debian Sid (I wanted a debian based rolling release, as fast as possible.. so a good netinstall was for me best solution).
So I faced the touchpad issue you reported.
Everything is now working by the way:
- ethernet is fine (did not try to change MTU on the fly 'cause i don't need)
- ACPI battery stats are ok and SDcard reader too (some warnings on boot, but just working ok)
- touchpad had errors but fixed (see below)
The problem with touchpad is that is recognised as standard ps2 wheel mouse instead of synaptic/ALPS touchpad.. so you cannot find even the touchpad tab under mouse settings and you get a stupid touchpad with unability to scroll or even tap to click.
I found a way to fix this TouchPad issue installing a custom driver and using dkms.
download this (currently newest package is 1.2):
(really say thank you to these people who wrote this driver, God bless them)
untar and copy (as root) the psmouse-alps-dst-X.x folder to your /usr/src directory (now X.x = 1.2)
once copied just run these commands
now you'll find the TouchPad tab under mouse settings and you can enable scrolling and so.. just because now is considered a touchpad and not a PS wheel mouse.
sudo dkms add psmouse/alps-dst-X.x
sudo dkms autoinstall
sudo rmmod psmouse && sudo modprobe psmouse
NOTE: if a new driver comes just the new one in /usr/source
and repeat the procedure.
For cleaniniess remove the old one with
where X.x is the number of the old version to remove from dkms.
sudo dkms remove psmouse/alps-dst-X.x --all
Then you can also remove the relative folder.
hope this helps. now I have a fully working touchpad.
