For me, the most important part here is suspend/hibernate events. I'm running Ubuntu 8.10, and I cannot put the computer to sleep during a workbreak. I once was about to leave the office, so I attempted to put the computer to sleep, but workrave activated right as I was doing that. Sleep failed, but the screensaver activated. Because of bug 763, I was unable to even quit workrave and had to just wait until the work break was over for me to be able to suspend the machine.
