I asked about ACPI several weeks ago but received no responses. Are suspend and hibernate features not supported in CentOS yet? I noticed there is a daemon for acpi: [scarolan at kalki ~]$ chkconfig --list | grep acpi acpid 0:off 1:off 2:off 3:on 4:on 5:on 6:off But how do I use this feature? Normally I'm accustomed to this being a menu option when I log out (eg, on recent versions of Fedora or Ubuntu). I noticed in /etc/acpi/events/ there is a file called sample.conf which configures the power button to attempt a graceful shutdown. How can I add a 'suspend' or 'hibernate' feature and bind it to a keyboard combination? thanks Sean
Well, this is just a tiny bit of the answer. But I do happen to know that you can initiate a suspend with: echo -n "mem" > /sys/power/state When it wakes up, you will probably have a black screen. This is expected, I think. There's more that needs to be done for a working suspend. But at least it may give you a clue if kernel support for suspend is available.

I have to pull the battery and cold start. Would like to know what else I need to do......> _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos > >
