I seem to have the same problem. I have turned off suspend/hibernate as those features does not work at all anyway. The screensaver blanks the screen after 5 minutes, I have no problem waking it up if I do it relatively soon after the screensaver kicked in. However, if I am away for a longer period (haven't measured the exact time) I can't get any response from the computer anymore. I'm using Ubuntu 11.04.
