Comment 91 for bug 380126

On my Ubuntu 10.10 with 2.6.35, the touchpad works even after suspend/resume, just that the settings from gpointing-device-settings are not remembered. For example, scrolling from the edge of the touchpad (the default, but previously disabled) works, but scrolling with two fingers (which I had enabled manually) doesn't. If I open gpointing-device-settings and re-check the checkboxes, everything is back again.

Also, I can confirm that you need the package that Paul Kolbovich mentioned to get multitouch to work: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/308191/comments/116
