When I click Suspend, all it does is the internet gets disconnected for a few seconds and than I get connected again. I have a Acer Extensa 4420 laptop. I appreciate any help. Thanks
I used to have the very same problem with an Acer Extensa with Intel + Intel internal video card. I have updated the graphics drivers from oibaf ppa repo:
after that suspend worked flawlessly. Try it and report here if it worked for you.
Hope this helps.
