Having problem with getting the Volume Up/Down & Mute/Unmute buttons on your Packard Bell EasyNote MX36 and Linux?
This might work for as it did for me. I was frustrated that these simple three buttons didn’t work anymore in Linux, those I’ve been running anyway(ubuntu & openSUSE), they used to work up till version 8.04 of ubuntu, in openSUSE i don’t know if they ever worked.
Sometimes it’s good to have the PC-Speaker enable, but for the most of the time it is just annoying and can drive you crazy, this tip will show you how to disable it. This has been tested on ubuntu, openSUSE & FreeBSD, if you know of other system this works on let me know.
On Linux(ubuntu, openSUSE):
1. Open up a console window and edit blacklist file.
$ sudo nano /etc/modprobe.d/blacklist
2. Add following to the end of the file and then save.
# Blacklisting pcspkr
blacklist pcspkr
3. Restart the computer.
On Unix(FreeBSD):
1. Run in console.
$ su root -c ‘ee /etc/rc.conf’
2. Add the following at the end of the file and save.
# Disable pc-speaker
modprobe -r pcspkr
3. Restart computer.

Below i have collected various tips that could potentially help you solve this problem.
Sometimes it is good to be able to automate some tasks that is run on regular basis, it’s here where crontab does the job. crontab is a scheduler for Linux/Unix where you can either add a command directly or a script with a lot of commands to be executed on set time intervals which you set as you please.
1. Edit crontab file for the user you want the job to run as, i use root as an example.
$ sudo crontab -u root -e
2. Add your desired entry in the format like this
60 * * * * /path/to/script/or/command
The format of the entry is, m h dom mon dow command.
m = Minutes(0-59)
h = hours, (0-23)
dom = Day Of Month(1-31)
mon = Month, values (1-12)
dow = Day Of Week(1-7)
command = The command that should be run on the specified time & date.
When running tar in a script run via crontab it often fails even when it runs fine from the console, this can be helped by adding ‘> /dev/null 2>&1′ at the end of the crontab entry your adding/have, must be before the last ‘&’ if there are one present at the end of the line.
