Comment 3 for bug 368170

I reported the bug for Ubuntu Jaunty, 9.04. I would still have the same problem if I didn't adjust the powerbtn script to include the check for xfce4-power-manager. All versions of the power manager are a problem, because the script runs before the daemon could catch it. I know for certain that the Jaunty shipped version (0.6.2) has the problem, but I no longer run that one (I added the karmic repo and installed Xfce from there due to Xfce version 4.6.1 bug fix release).

The other buttons, like the lid and sleep button were picked up properly, because I don't have the acpi-support scripts installed that take care of these events. No scripts for the event means that the power manager takes over, or nothing happens.
