Package: laptop-mode-tools
Version: 1.58-3
Severity: normal
Dear Maintainer,
The /usr/lib/pm-utils/power.d/laptop-mode script which is executed by a hook
fails to return the original /proc/sys/vm/[laptop_mode, dirty_ratio,
dirty_background_ratio, dirty_writeback_centisecs] values after AC power is
reattached.
On first boot with AC power attached,
>/etc/init.d/laptop-mode status

The main differences are the /proc/sys/vm/ files:
1. laptop_mode: is now 2 instead of 0.
2. dirty_ratio: is now 60 instead of 10.
3. dirty_background_ratio: is now 1 instead of 5.
4. dirty_writeback_centisecs: is now 60000 instead of 500
