suspend and touchpad issues on acer aspire 5534

[h3rm35]

Two issues, that I have to address, and I hope it's ok to deal with them in the same thread, since they're both hardware related (I think).
I have and Acer Aspire 5534 laptop that I recently installed isadora dual boot over an existing windows 7 install.
First thing is that the cursor seems to be randomly epileptic while manipulating the touchpad - that is, as I move the arrow around the screen, it will randomly fly all over the screen in different directions. I've reduced its sensitivity drastically and disabled clicking by tapping it in the control center, and both of those seemed to reduce the problem, but it still remains.

Second thing is that I've tried numerous time to stop the computer from suspending after a period of inactivity and nothing seems to work. I've searched the forums for a solution, but it seems as though this type of thing is very specific to individual set-ups, so here I am asking...

I'm no expert at dealing with linux issues, but I have been using both Ubuntu and Mint for over a year now, so I've got some basic stuff down, but I wasn't a command-line commando in my previous life as a windows user either, so please be patient with me.

go to > Menu > Preferences > Screensaver
see if unchecking Lock screen when screensaver is active will alleviate this trouble.

Great! thanks so much, that seems to have worked... anyone have any ideas about the epileptic touchpad?
