Ubuntu 10.10 upgrade on T400s

Upgraded from 10.04. Installation was smooth but no idea how to activate touchpad multitouch features - something to do with evdev vs synaptics in xorg config? Also, the headphone jack doesn't seem to work; the speakers silence but the headphones don't work when I jack in. Probably easier to do a fresh install.

- I did a fresh install and had the same problem. Have a look at https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/600096 to fix that. Further suspend didn't work anymore fore me. See https://bugs.launchpad.net/ubuntu/+source/pm-utils/+bug/666172?comments=all for a workaround.
