Laptop Mode Tools 1.60 Released
Written for Laptop Mode Tools by Ritesh Raj Sarraf on 2011-10-14
Hello World,
I am very pleased to announce the release of Laptop Mode Tools, version 1.60.
This release includes lots of bug fixes and should make power savings much better on your machines.
The battery polling daemon now, more reliably, gets triggered and killed based on power states.
This release also includes 2 helper scripts to trigger suspend and hibernate, in case anyone is interested.
Given the advancements of Linux PM (All thanks to Rafael J. Wysocki) in recent years, the freezer/thaw
functionality really does a very good job of handling suspend/hibernate, there is no need of a hacky suspend/resume
mechanism. Thus, you'll notice the helper scripts just do a mere echo into sysfs.
I would also like to thank the Chromium project that has found and fixed many bugs and added many enhancements to Laptop Mode Tools.
Changelog:
1.60 -- Fri Oct 14 13:08:09 IST 2011
