If ACPI is enabled then closing and opening the Lid generates an ACPI event on some notebooks, which can be handled by acpid. On my asus closing/opening the lid generates button/lid LIDD 00000080 00000003 button/lid LIDD 00000080 00000004 in /proc/acpi/event Another solution would be to create a /etc/nologin file (it's existence disabled non-root logins), wait until the user logs out and perform the update then, afterwards delete it. At least that would be the way I would do it on a server. Yours, Karsten -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
