Hi everyone,

I just installed ubuntu 11 on a LG RD510 laptop, that has a synaptics touchpad.

The immediate installation worked smoothly and the touchpad worked well,
but after running the update (138 MB worth of updates), and a restart, it stopped working completely ("mouse" cursor doesn't respond and the buttons don't work either).

I tried reverting the package "xserver-xorg-input-synaptics", which seems to hold the driver to the touchpad, from the latest 1.39 to 1.2.2, but it had too many dependency issues and wants me to revert back to previous xserver and other packages' versions.

Any idea what this is about and how to fix it?
