Linux - change brightness

reference : http://www.thinkwiki.org/wiki/LCD_Brightness

This worked for my X61:
Once your brightness keys work, you can set the brightness by writing to the procfs:

# echo 100 > /proc/acpi/video/VID/LCD0/brightness

using a script and acpid events.

Linux - Burn CD using command cdrecord

cdrecord -v -dao -eject speed=8 dev=1,0,0 file.iso

Answer me first before log a call

While waiting for the explorer data. I would like to understand:
1) When you first discover the amber light is on?
2) Is there any software installation/maintenance been performed recently?
3) Is there any hardware installation/maintenance been performed recently?
4) Is there any recent power failure?
5) What action you have tried to troubleshoot?
6) Do you notice any other abnormal situation (e.g. daemon down, network not working, etc)? Or the server still running as usual?

Thank you.

Linux - Enable root passwd

from : http://www.ubuntugeek.com/enable-and-disable-ubuntu-root-password.html


If you want to enable root account (which is not recommended) enter the following command.

$sudo passwd root

This will prompt for a new root password and once you confirm it, you can start using the root account to login.

If you want to disable root account in ubuntu you need to lock the root account by using the following command

$sudo passwd -l root

If you want to work on a root console you’d better use the following command

$sudo -i
