root@vi-notebook:/home/vi# laptop_mode start force Laptop mode enabled, not active
How to start laptop mode? It starts successfully when AC adapter is removed, but not by explicit command.
The system is GNU/Linux Debian i386 squeeze (not up to date), 2.6.30-zen2-31270-gc7099db-dirty, Acer Extensa 5220.
Update:
Changed to ENABLE_LAPTOP_MODE_ON_AC=1 in /etc/laptop_mode/laptop-mode.conf, now it is turned on always. But I can't turn it off with laptop_mode stop force, it stays turned on anyway.
How do I turn it off again?
Update 2:
Implemented hardcore solution, "radical laptop mode": http://vi-server.org/vi/code/kernel/0003-block-Introduce-hung-iosched.patch
It just forces HDD to be off until I explicitly allow access to it again (all requests get hung).
