One Stop solution for adjust screen brightness in Linux

This one is just temp/quick fix for brightness issue for Linux machines. Some people, like me cannot stand with higher values of computer screen brightness. We surely adjust as per our eye suitability.  But what if we work on Office Machines or using a friend’s one ? May not all the time, we shall have full permission to change the screen brightness. In such cases, this quick fix can be a heaven for your eyes. 😛


we find which display device we are connected to. open your Terminal and fire this below command. Please dont type ‘#’ also. It is for just to indicate that is a terminal / shell env.
#xrandr -q | grep ” connected”

Now, this will output the connected display such as

VGA1 connected primary 1366×768+0+0 (normal left inverted right x axis y axis) 344mm x 194mm 

This is in my case, but it will vary as per systems. For me VGA1 is my display. Some times it may show LVDS1 and so on.

Now, use the second command for set up our brightness level

#xrandr –output VGA1 –brightness 0.6

that is, we set the brightness 60% of maximum brightness. This is ok for my eyes, but not for my Boss, so whenever he leans to my monitor for some thing, I will set this back to 1. voila !

So thats how Save Eye from Blindness going !! 😛


Install and setup Odoo 9.0 in Ubuntu/Debian Distro

Odoo is an enterprise class level ERP suite, in fact it can replace so many applications on a row. You can find such lists here -> Replace all your business apps with Odoo 9

Now,  to install Odoo Server in your  Dev Server, a lil bit edgy, need some touch  of a human hand. Lets see how to do that. As per the Odoo documentation, which have installation instructions for windows, Linux(deb/rpm) etc. Lets go for Debian/Ubuntu choice.

We are going to install Odoo using apt-get, the awesome package manager of Debian world. First we have to add the Odoo repo to our apt-source list and GPG key. For that, fire the below command line / terminal

wget -O – | apt-key add – 

Then fire the next command to add repo list

Mind the version name and update repo package info and install odoo

echo ‘ “deb ./” >> /etc/apt/sources.list  ‘


NOTE :- To print PDF reports, you must install wkhtmltopdf yourself: the version of wkhtmltopdf available in debian repositories does not support headers and footers so it can not be installed automatically. The recommended version is 0.12.1 and is available on the wkhtmltopdf download page, in the archive section. As there is no official release for Debian Jessie, you can find ours on

 apt-get update && apt-get install odoo

This will  install odoo server in dev machine. Lets assume this step pass with no fail. Now  open your web browser and go to http://localhost/8069

Note that 8069 is the default port for Odoo Server. You will get a prompt for setting up Admin password  and Database name. Just fill up those and install button, then  it will take to administrator backend.


Voila, your Odoo Server is ready ! You can explore and try more things as you wish, you can get help from Odoo website itself for more info
