Misc memo. disable/enable touchpad via xinput, sent a patch to rhbz 732182.

This is a simple script to Disable/Enable touchpad from terminal via xinput.

#!/bin/bash

val=0

if [ "$#" = "1" ]; then
    val=$1
fi

touchpad_device="FSPPS/2 Sentelic FingerSensingPad"

device_num=`xinput list | grep "$touchpad_device" | cut -d'=' -f2 | awk '{ print $1 }'`
xinput set-prop $device_num "Device Enabled" $val

if [ $val = 0 ]; then
    echo "TouchPad Disabled"
else
    echo "TouchPad Enabled"
fi

exit 0

Bug 732182 looks timing bug. The bug arose strcmp(3) in refresh_task_list() at line 149. The refresh_task_list() is called from timer handler so if this function is called while gtk objects are releasing, it would be dangerous I think.

148:    sprintf (tooltip, _("Memory: %d MB of %d MB used"), memory_used / 1024, sys_stat->mem_total / 1024);
149:    if(strcmp(tooltip,gtk_progress_bar_get_text(GTK_PROGRESS_BAR(mem_usage_progress_bar))))

So I reckon it is safe to remove timer event in on_quit().
