# thinkpad_acpi_events - process ThinkPad specific ACPI events generated by
# ibm_acpi driver and log them to syslog
#
# Configuration changes required for the script to work with powersave package:
# 1) Set EVENT_OTHER="thinkpad_acpi_events" in /etc/sysconfig/powersave/events
# 2) Place this script into /usr/lib/powersave/scripts directory

# Customized by Huahai Yang to support Thinkpad X61 ACPI keys on KDE.
# Added on screen visual feedback for key press, the following keys are 
# supported on top of existing powersaved supported keys:
# - Fn+F1 to start wireless connection
# - Fn+F2 to lock desktop
# - Fn+F3, F6, F8 to switch among Powersave, Performance and Presentation
# mode
# - Fn+F7 to toggle external display
# - Fn+F11 to start LAN connection 
# - Fn+Home, Fn+End to increase, decrease LCD brightness
# - Fn+Space to toggle screen resolution
# - ThinkVantage to open konsole
