Having fun with IBM ACPI

It's always cool to play with ibm-acpi.


as root

modprobe hdaps

then

yum install neverball

And run the game. Move your laptop in the air to make the ball move... Sooo cool

Also, smack the screen to switch destops,

run the following script in python

smack.py
#!python

import sys, re, time
import wnck, gtk

INTERVAL = 0.01
POS_FILE = '/sys/devices/platform/hdaps/position'
CAL_FILE = '/sys/devices/platform/hdaps/calibrate'
POS_RX = re.compile('^((-?d+),(-?d+))$')
SENS = 4

workspaces = None
current_ws = None

def flush_events():
while gtk.events_pending():
gtk.main_iteration()

def get_all_workspaces():
global workspaces, current_ws
scr = wnck.screen_get_default()
flush_events()
current_ws = scr.get_active_workspace().get_number()
workspaces = [] 
for i in range(scr.get_workspace_count()):
workspaces.append(scr.get_workspace(i))

def switch_to_workspace_n(n):
global workspaces
workspaces[n] .activate(0)
flush_events()

def swicth_to_workspace_at_right():
global workspaces, current_ws
current_ws = (current_ws + 1) % len(workspaces)
workspaces[current_ws] .activate(0)
flush_events()

def swicth_to_workspace_at_left():
global workspaces, current_ws
current_ws = (current_ws - 1) % len(workspaces)
workspaces[current_ws] .activate(0)
flush_events()

def get_pos():
pos = open(POS_FILE).read()
match = POS_RX.match(pos)
return (int(match.groups()[0] ), int(match.groups()[1] ))

def get_calibration():
pos = open(CAL_FILE).read()
match = POS_RX.match(pos)
return (int(match.groups()[0] ), int(match.groups()[1] ))

def loop():
calx, caly = get_calibration()
stable = 0
while True:
x, y = get_pos()
if x == 0: continue
delta = x - calx
adelta = abs(delta)
if adelta < 5:
stable += 1
if adelta > SENS and stable > 30:
stable = 0
if delta < 0:
swicth_to_workspace_at_right()
else:
swicth_to_workspace_at_left()
time.sleep(INTERVAL)

def main():
get_all_workspaces()
try:
loop()
except KeyboardInterrupt:
pass

if __name__ == '__main__':
main()

then hit your screen from the side... see how your desktop change...
