For some reason the touch pad isn't working on my Acer Aspire E5-573G-59C3. I checked the System settings and it's turned on there. I've tried the keyboard shortcut for turning it on and off, but no joy. I've looked over numerous peoples postings for help, but I haven't found anything that works for me. I tried adding some packages from the package manager still nothing. Does anyone have any idea how to fix this? I'm guessing it's a driver issue, but maybe it's not. Any help would be greatly appreciated.
