Post Install Tweeks, That would make life easyer Options

Having installed ZUBUNTU for the first time, here are some bits that people might find of use

after loging in the first time run

ts_calibrate

to calibrate your touch screen

run killall tskeys

to get some free memory

ensure dhcp is running properly by changing the 102 and 103 entries for dhcp in /etc/passwd to 0

get your wifi / network running by looking on the forums

once you have internet connectivity, install synaptic so you can find packages with

apt-get install synaptic

now you're ready to rock

Here is my script:

CODE

#!/bin/sh
ONE=$(grep Spitzkbd /proc/interrupts|md5sum)
while true
do
sleep 240
PLAYING=$(mpc|grep "play"|wc -l)
if [ "$PLAYING" = 0 ]; then
TWO=$(grep "Spitzkbd\|ts" /proc/interrupts|md5sum)
#echo $ONE $TWO
if [ "$ONE" = "$TWO" ]; then
apm -s
fi
fi
ONE=$TWO
done

File with interrupts (/proc/interrupts) looks like this:

CODE

I think ide0 contains number of interrupts for cf card and pxa2xx-mci contains number of interrupts for sd card.

If you want to check activity of network card just check output of ifconfig and look for eth0, ppp0 wifi activity represented by number of bytes,sent/received.

In my case it was not important how much keys was pressed i just needed to know if anything happened so i used md5sum to check that.

There is a lot of ways to achieve result which You need, just peek in /proc or /sys and with simple script monitor what is happening in those files while You are doodling with zaurus and then write script to use that information and react.
You can use beeping instead led flash. Or you can try aosd_cat as a OSD visualizer.


I have written a small utility to show vital signs of my zaurus. I connected it to a keypress using .xbindkeysrc:
Look at "#show" battery section. When you press FN and 0 (zero) then /bin/batt script is executed.
Also Fn+9 is mpd toggle and fn+8 and Fn+7 is next and prev song

It is helpful to use xev to check which codes are generated by X while pressing keyboard keys.

Here is a batt script:
It shows some nice information about Z

CODE

#!/bin/sh

a=$(cat /sys/devices/platform/sharpsl-pm/battery_percentage)
f=$( free|grep Mem|awk '{ print $1 int($4/1024) }'|tail -n 3|tr "\n" " ")
l=$(top -b -n 1|grep "load average"|cut -d "," -f 3-6|cut -d ":" -f 2)
d=$(date)
s=$(amixer sget PCM|grep "\["|cut -d " " -f 4,6)


TEKST=$(echo -e "PCM\n$s\n$d\nbatt:$a \n$f \nload:$l")

echo -e "batt:$a $f load:$l"
if [ "$1" = "osd" ]; then
aosd_cat -d 5000 -e 0 -F "Trebuchet 30" -s 3 -S 100 -r 1 -g 1 -b 0 -x 30 -y 30 -t "$TEKST"
fi

And one more:

CODE

pcm script (used to change volume)

#!/bin/sh


STEP=3

if [ ! -n "$1" ]; then
echo "max / current"
amixer sget PCM
elif [ "$1" = "up" ]; then
amixer sset PCM $STEP"%+"
elif [ "$1" = "down" ]; then
amixer sset PCM $STEP"%-"
else
echo -e "\nUsage:\n\t `basename $0` [up | down]\n"
fi

And if I remember correctly I have changed slightly standard zubuntu script to change display brightness.

CODE

#!/bin/sh

# display-brightness.sh

STEP=5
MAX_BRIGHTNESS=47
MIN_BRIGHTNESS=0

DRIVER="`ls /sys/class/backlight/|head -n 1`"
BRIGHTNESS_FILE="/sys/class/backlight/$DRIVER/brightness"
BRIGHTNESS=`cat /sys/class/backlight/$DRIVER/actual_brightness`
# this gives bad number - 15 is max, 16 is off!
#MAX_BRIGHTNESS=`cat /sys/class/backlight/$DRIVER/max_brightness`

POWER_FILE="/sys/class/backlight/$DRIVER/bl_power"
POWER_ON=0
#POWER_OFF=1


if [ ! -n "$1" ]; then
echo "max / current"
echo "$MAX_BRIGHTNESS / $BRIGHTNESS"
elif [ "$1" = "up" ]; then
test -x /usr/bin/bl && bl on
echo $POWER_ON >> $POWER_FILE
if [ $BRIGHTNESS -lt $MAX_BRIGHTNESS ]; then
let BRIGHTNESS=$BRIGHTNESS+$STEP
if [ $BRIGHTNESS -ge $MAX_BRIGHTNESS ]; then
let BRIGHTNESS=$MAX_BRIGHTNESS
fi
echo $BRIGHTNESS >> $BRIGHTNESS_FILE
fi
elif [ "$1" = "down" ]; then
test -x /usr/bin/bl && bl on
echo $POWER_ON >> $POWER_FILE
if [ $BRIGHTNESS -gt $MIN_BRIGHTNESS ]; then
let BRIGHTNESS=$BRIGHTNESS-$STEP
if [ $BRIGHTNESS -le $MIN_BRIGHTNESS ]; then
let BRIGHTNESS=$MIN_BRIGHTNESS
fi
echo $BRIGHTNESS >> $BRIGHTNESS_FILE
fi
elif [ "$1" = "off" ]; then
if [ $BRIGHTNESS -ne 0 ];then
echo "$BRIGHTNESS" >/tmp/backlight
echo 0 > $BRIGHTNESS_FILE
fi
elif [ "$1" = "on" ]; then
cat /tmp/backlight > $BRIGHTNESS_FILE
rm /tmp/backlight
else
echo -e "\nUsage:\n\t `basename $0` [up | down]\n"
fi

Combined together with .xbindkeyrc, those give quite nice result in usability of the zaurus. Dont forget ro run xbindkeys in your ./homedir/.xinitrc. the saver script is also executed there with background option (& ampersand at the end of a command)
BTW I use matchbox WM so there is not much to put in panel to monitor OS condition thats why i have those scripts.
Aosd_cat is quite slow to start but I use it rarely so it is not a problem.
