Running gconftool-2: gconf-editor From Shell


Basically gconftool-2 is to be done is allow you to set the gnome environmet tweaks (font size, the sound mixer settings, taskbar size / location, etc.) from the shell vs. using graphical tools.

gconftool-2 example

Below is an example of using the gconftool-2 to set the default font size to 8, because I've done in the EeePC.

$gconftool-2 - set/apps/nautilus/preferences/desktop_font - type string "Sans 8"

$ gconftool-2 - set/desktop/gnome/interface/document_font_name - type string "Sans 8"

$ gconftool-2 - set/desktop/gnome/interface/font_name - type string "Sans 8"

$ gconftool-2 - set /apps/Metacity/general/titlebar_font - type string "Sans Bold 8"

$ gconftool-2 - set /desktop/gnome/interface/monospace_font_name - type string "monospace 8"

The above command is the same with the launch gconf-editor (ALT-F2: gconf-editor), navigate to the path listed above and change the values listed. Although I very grateful that we have a graphical tool to edit these things, you tell me which is faster?

gconftool-2 basics

Basic structure using gconftool-2 is as follows:


$ gconftool-2 - set/path/to/settings - the type of "value"

In/path/to/settings can be found by using the graphical tool (unless someone can tell me an alternative method). This can also be found in the same place. For example, let's say I want to change the value to switch the screen when the screensaver is in use. I can open gconf-editor GUI tool, navigation through the menu tree "apps> gnome-screensaver" to search for "lock_enabled" value. Usually, by checking the box or not we will move this value.

Using gconftool-2, we can achieve the same thing with:


$ gconftool-2 - set/apps /gnome-screensaver/lock_enabled-type bool 1 "

Now I understand that at this time we do not technically any more quickly because we have to look up in the GUI, but it was found after the first time you must first game of the second time. This is good to install multiple machines, or if you reinstall your computer regularly and want to script your settings back into place.

Available on the basic structure of our value-set, providing a path to the value of what we want to change, and then determine the type. In this case he is dead or on the boolean value. In other cases, such as with the example above, is a string that must be defined. You can find out the type of value (integer, boolean, string, etc.) use your item by double-clicking in the graphics application.

I have been able to find values in the gconf-editor or gconftool-2. Start from the right mixer for toggling volume settings to determine the size of a particular taskbars.

I hope the basic example above can provide.

Happy Testing....!!!

Install Google Earth On Ubuntu 8.10 Intrepid Ibex


Installing Google Earth for Adding Repository necessary, follow the steps below:

Set up the Medibuntu Repository

As mentioned above, the first thing you need to configure is adding the Medibuntu repository. Setting up this third-party repository can be done with a few quick commands:


$ http://www.medibuntu.org/sources.list.d/intrepid.list sudo wget-O /etc/apt/sources.list.d/medibuntu.list

$ sudo aptitude update & & sudo aptitude install medibuntu-keyring & & 
$ sudo aptitude update

This will add the Medibuntu repository, import the Medibuntu GPG key and make new packages available.

Installing Google Earth

To install Google Earth, then simply use:

$ sudo aptitude install googleearth-4

You should now have Google Earth added to the "Applications> Internet" menu and, assuming your video card supports the requirements, you are almost ready to travel the planet!

Depending on the video card you may want to disable the atmospheric rendering, which can greatly increase performance. This can not be done by setting the following:

View> Atmosphere

If, for some reason, Google Earth does not load properly or crashes on your computer may try to return to the old version that seemed to have a little problem. To do that and try to remove 4.3 version 4.2:


$ sudo aptitude googleearth-4, 3 & & sudo aptitude install googleearth-4, 2

Happy Testing.

Change tmp Directory Cleanup Frequency In Ubuntu

Changing the /tmp Cleanup Frequency

The default setting that tells your system to delete the /tmp at reboot be in /etc/default/RCS file. Akan value we see is TMPTIME.

At the time of this value TMPTIME = 0 to delete the file on reboot even though the age of the file. Changing this value to a different (positive) number will change the number of days can be spent on the file tmp.

TMPTIME = 7

This setting will allow to stay in the file /tmp them until a week old, and then delete them on reboot. Negative number (TMPTIME =- 1) tells the system to never delete anything in /tmp. This is probably not something you want, but available.

this way on Ubuntu, and finally found this day.
