Ubuntu 12.04 Change Default Resolution When No Monitor Connected

I have a Linux Ubuntu 12.04 computer running without a monitor. I usually access it via VNC viewer, when I access it normally I would get 1024 x 768 over the remote VNC viewer application. I wanted to change the default resolution from 1024x768 to 1920x1080. To do this I researched on Google and couldn't find a simple answer. I finally came across the solution and here it is.

To change the resolution of screen on Ubuntu 12.04 when no monitor is connected you have to do the following.

Create the xorg.conf file if it doesn't exist under /etc/X11/ director
sudo nano /etc/X11/xorg.conf

Paste the following content in that file
Section "Device"
       Identifier      "Default Device"
       Option  "NoLogo"        "True"
EndSection
Section "Monitor"
   Identifier    "Configured Monitor"
EndSection
Section "Screen"
   Identifier    "Default Screen"
   Monitor        "Configured Monitor"
   Device        "Default Device"
   SubSection "Display"
       Depth    24
       Virtual 1920 1080
   EndSubSection
EndSection
Save that file Ctrl+X and yes, hit enter.
Change the virtual resolution from 1920 1080 to what ever you preferred resolution is.

Now reboot.

You changes will apply once you reboot and next time you use VNC to view you Ubuntu desktop your resolution will be what ever you had it set to in the xorg.conf file.

Blogger: How to get values from URL parameter?

Mainly there are two ways that you can achieve this task of getting parameter values from URL on Blogger platform.

1. One way is by getting values from built-in parameter for certain page types. There are certain pages on Blogger that accept parameters from URL, for example:  search page has an input parameter called "q=SOME_VALUE", label page also has an input parameter "/search/label/VALUE"

a. The pattern for Blogger search URL is http://sub-domain.blogspot.com/search?q=VALUE
b. The pattern for Blogger label page is http://sub-domain.blogspot.com/search/VALUE

Lets me do a tutorial to teach you what you can exactly do by getting values from built-in blogger URL parameters. I am going to create a script that will allow you to embed any youtube video by getting the video id from a url parameter.

Each YouTube video has a specific video id, here is pattern for YouTube video page URL:
https://www.youtube.com/watch?v=VIDEO_ID

Lets look at a YouTube video link:
https://www.youtube.com/watch?v=R4em3LKQCAQ

We know that the video ID for that video is R4em3LKQCAQ.

What we want to do is to embed that video on our blog by inputting the video id as a URL parameter. So, we can achieve task in two ways, either by writing script that will let you embed the video by visiting:
http://sub-domain.blogspot.com/search?q=R4em3LKQCAQ  or
http://sub-domain.blogspot.com/search/label/R4em3LKQCAQ

Simplest script would be to check condition if the search page query parameter q has some value and if yes, therefore, iframe the video with the parameter that has been entered. Example is
<b:if cond='data:blog.searchQuery != &quot;&quot;'>
<iframe width="560" height="315" src="http://www.youtube.com/embed/<data:blog.searchQuery/>" frameborder="0" allowfullscreen></iframe>
</b:if>
If you have the above code in you template and you visit page:
http://sub-domain.blogspot.com/search?q=R4em3LKQCAQ

You will see the video iframed with the ID that you input for parameter "q". You can basically change the parameter q to any video ID that you want to embed.

The script for label page would be different, to embed video on label page you want to check condition if page type is lable and use the pagename tag to use what you have inputted for the video ID. Your script would look something like below:
<b:if cond='data:blog.pageType == "data:blog.searchLabel"'>
<iframe width="560" height="315" src="http://www.youtube.com/embed/<data:blog.pageName/>" frameborder="0" allowfullscreen></iframe>
</b:if>
If you put the above script in your template and you visit page:
http://sub-domain.blogspot.com/search/label/R4em3LKQCAQ

That would embed the video on your label page with the id that you input as label name. Similarly you change the video ID to any other video and it will embed that new video on your label page.



2. Second way of getting the value from URL parameter on Blogger would be by using javascript. This is done on the client side, so basically, you can put any parameter on any page type where ever you want.


I am tired now, if you want to know more let me know in comments and I will write rest of the post. Enjoy.
