I followed the guide. Codesnipped listed under 2.6 is wrong and returns an error. Code should be: tail -f /var/log/messages | grep "received event" instead of: tail -f /var/log/acpid | grep "received event" I found an entry in one of the logfiles: /var/log/portage/elog/summary.log:As of version 1.0.6, acpid uses system log facility instead of custom log /var/log/portage/elog/summary.log:file. This means acpid messages will be usually located in /var/log/portage/elog/summary.log:/var/log/messages (and not in /var/log/acpid) for common setups. The guide needs to be updated! Reproducible: Always Steps to Reproduce:
Code Listing 2.6 (Determining ACPI events for changing the power source) is wrong
Fixed in CVS. Thanks for reporting!
