I am currently experimenting with using Ubuntu as a my main OS instead of Windows 7. So far, pretty much everything is working fine, except for an issue that I am having with my touchpad.

I have a Dell XPS 16 (1640) with a Synaptics touchpad. It works out of the box, but it seems that it stops working after returning from hibernation mode.

This problem has also been addressed in an earlier bug: but judging from this bug report, it should be fixed by now.

I am running the 2.6.35-23-generic-pae kernel.

Any ideas?

This question came from our site for users of Linux, FreeBSD and other Un*x-like operating systems.

You may be hit by this bug instead:

A workaround is suggested, to restore touchpad functionality reload the psmouse module, in a terminal do:

sudo rmmod psmouse; sudo modprobe psmouse

If this solves the problem then this is likely the bug affecting you. Note that a fix is in recent kernels, so upgrading to either Ubuntu 11.10 (with kernel 3.0.0-16) or 12.04 should solve the issue.
