- The powermanagement callouts in the default hal config
- (org.freedesktop.Hal.Device.SystemPowerManagement and
- org.freedesktop.Hal.Device.LaptopPanel) and the storage callouts
- (org.freedesktop.Hal.Device.Volume.*) can be used by users on a local
- physical console.

- The acpi addon won't use the kernel acpi events interface but the acpid's
- event socket if acpid is installed. If acpid is removed, hal needs to be
- restarted to enable monitoring of acpi events again. And if apci is installed,
- hal needs a restart to free the kernels acpi events interface for acpid.

- Some CD and DVD drives, such as the GDR8162B model found in some Dell
- laptops, do not correctly handle media status inquiries and incorrectly
- spin up the drive when they should not. Since hal regularly polls CD
- drives for media changes, this results in increased power consumption and
- mechanical wear and tear on such drives, which remain spinning constantly
- while hal is running.
-
- If you have a CD/DVD drive exhibiting this problem, you can copy
- /usr/share/doc/hal/examples/no-cd-media-check.fdi to /etc/hal/fdi/policy/ to
- disable media checks for your drive. This file disables media checks for
- all CD drives on the system, and also includes an example config for
- disabling media checks only on a specific drive.
