Public bug reported:
Binary package hint: laptop-mode-tools
When switching from battery to AC or when booting on AC, laptop-mode
thinks it's still running on battery and doesn't apply the correct
settings for AC.
valen...@valentin-laptop:~$ cat /var/lib/acpi-support/powerstate
BATTERY
valen...@valentin-laptop:~$ cat /proc/sys/vm/laptop_mode
2
valen...@valentin-laptop:~$ cat /var/lib/acpi-support/powerstate
AC
valen...@valentin-laptop:~$ cat /proc/sys/vm/laptop_mode
2
Restarting laptop-mode seems to fix things, so maybe it's the way
laptop-mode is run from the acpi-support scripts?
valen...@valentin-laptop:~$ sudo /etc/init.d/laptop-mode restart
* Disabling laptop mode... [ OK ]
* Enabling laptop mode... [ OK ]
valen...@valentin-laptop:~$ cat /proc/sys/vm/laptop_mode
