view story

http://ubuntuforums.org – Hello all, I have an Acer eMachines E725 and I just completed a fresh install of Xubuntu 12.04 but now I can't seem to get my touchpad working. It did not work during installation, but it did work briefly during the next login session. Now...no luck. I go to Settings Manager->Mouse and Touchpad, but the touchpad doesn't show up under Device. Any suggestions? Also, now there's a high pitched whine emitting from inside my computer. It's not the hdd spin b/c that's on the other side. I have this machine dual booted and Windows does not have this problem. Also, the old kernel from Ubun (Hardware)
