so i tried connecting it to another monitor and it did work but after installation and installing latest update and drivers the problem still exist on the main monitor :S

so after some googleing and trying deferent solutions i found out that the problem in screen brightness level,  for laptop monitor the level is  0 or less "total black"  which is weird,  and the fn key is working in wrong way "inversed" WTH!! ,

to adjust the level you need to hit f3 without fn key :S , or find the solution the hard way  by setting it in this file /etc/rc.local by adding the following line before exit 0

echo 5 > /sys/class/backlight/acpi_video0/brightness
exit 0

Where 5 is the brightness level from 0 to 10

Net Applications, a Web site analytics company, just published their April 2009 Web users survey, Market Share, and they found that "Linux usage share on client devices has surpassed 1% for the first time and we still have 99% to go and i think it can make it , thanks to some powerful distributions like Ubuntu,Fedora and OpenSUSE.

1. New Ext4 file system support
2. Faster boot time almost 20 sec "wow" check this video
3. New network manager and its way better and easier comparing to 8.04
4. Nautilus 2.26.2 and tabs thing very useful
5. New notification area which rocks
6. The shutdown/restart/suspend options have been taken off the System main menu
7. Wallpaper transformation

last thoughts :

comparing to 8.04 its way faster,better and sexier , and here is my desktop final look

I'm not saying boycott windows or any closed software's i think there existence is important to show us how Linux is important

• as we know ssh don't accept password to be written it something called "interactive keyboard password authentication" so we need some help , install sshpass

$ sudo aptitude install sshpass

Using sshpass you could send password to ssh example("sshpass -p YOURPASS ssh USER@HOST")

note: this is not secure at all so don't use it for online servers.

• Now all what we need is to put it as command-line aliases or shortcut , to do that add these lines to bashrc file

alias Myssh='sshpass -p YOURPASS ssh USER@HOST'

note: to access bashrc file  $ nano ~/.bashrc

and now all what you have to do just write Myssh in terminal and you are in
