After further investigation I found a set of options in a new section of the xfce4 configuration menus dealing with power managerment which have solved my problem.
The settings of acpi-support are being overridden by the xfce4 settings. Choosing the behavior I want from the xfce4 configuration system restores it. Sorry to have bothered you. -- Bert Riding [email protected] gnupg fingerprint: C0F6 E202 EFB3 F332 CAB0 85D4 A113 9F46 3C93 5A6E -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
