Intel graphics restored on Ubuntu Jaunty.. Compiz works!

June 23rd, 2009

With the new Intel drivers on Ubuntu Jaunty, the Compiz was prone to crash frequently. The Ubuntu developers had pushed certain Intel chipsets into blacklist, hence no compiz or the desktop effects for Intel users on Jaunty. There were a couple of workarounds to enable the compiz effects (See my post here), but they are workarounds - each one having it’s own pros and cons.

Today Ubuntu team pushed new updates, and one of the update related to the Intel graphics. The blacklist entries have been removed now, and the new Intel graphics driver works flawlessly with Compiz and the desktop effects. Waiting for this from a long time, Thanks a lot Ubuntu team!

Hide Beagle Icon from Notification/Tray area

June 9th, 2009
Beagle is a great alternative to resource consuming Google Desktop for Linux. Beagle has almost all the search features provided by GDL and is pretty fast too. When you install Beagle, you can see that a icon appears in the Tray area (Notification area). Disabling it is pretty simple:

Go to System>Preferences>Startup Applications, and uncheck “Beagle Search Tool”.

Don’t uncheck the Beagle Search Daemon. From the next restart, you won’t get the icon. You can launch the Beagle application from Accessories>Search :-)

Ubuntu Repositories: Pidgin Instant Messenger

June 9th, 2009

Ubuntu ships Pidgin but does not update it after a release (except for
security issues). For those users– who desire new releases of Pidgin, the official PPA:

Importing the GPG Key:

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com \

67265eb522bdd6b1c69e66ed7fb8bee0a1f196a8

Adding to sources list:

. /etc/lsb-release

echo deb http://ppa.launchpad.net/pidgin-developers/ppa/ubuntu \     `lsb_release –short –codename` main | \

sudo tee /etc/apt/sources.list.d/pidgin-ppa.list

Don’t worry about your version specific PPA, the above code will add your ubuntu distro’s version automatically. Once this PPA is setup, Pidgin updates will show up in Update Manager along with the usual Ubuntu updates.

HowTo: Google Calendar on GNome Clock Applet

June 8th, 2009

Here is a very simple way to add events from your google calendar to the Clock applet of your GNome Panel. It uses Evolution application for the integration.

Step 1: Get the private iCal URL of the Calendar from the Settings of your google calendar

Step 2: Paste it into the Firefox’s address bar, and change the http:// to webcal:// and press enter

Step 3: Firefox will popup the application selector. Select the evolution-webcal

Step 4: Enter the refresh time, and a color for the calendar and press Subscribe

That’s it! Pretty easy, isn’t it? You can see the events from your Google calendar now in your GNome panel’s clock applet…

This Howto is done on Ubuntu Jaunty, but the procedure will be pretty much the same for any other linux flavour, provided evolution is installed.

Disabling Background Fade in GNOME, Jauntyt

June 8th, 2009
In Jaunty, one of the new features of GNOME desktop is the smooth fading effect when changing the background wallpapers. It’s a nice feature, but I have a small panel applet Webilder, which changes the wallpaper randomly at equal intervals of time. I’ve kept the time to be 1 Minute, and there are some high resolution wallpapers in my collection.

My integrated graphics (Intel chipset) wasn’t able to handle that kind of animation and every minute when the wallpaper changes, the system becomes slow and sluggish. After googling for disabling this particular fading effect, I wasn’t able to find the exact solution, but a work around: Disabling the GTK Animations.

Create a file .gtkrc-2.0 in the home directory, and add

gtk-enable-animations = 0

to that file. Logout/Restart, and all the GTK Animations are disabled, including the fading effect. I don’t know at this point of time what are the other animations that are disabled, but right now, the system is much better in responsiveness than before! :-)

Foxit Reader for Ubuntu

June 8th, 2009
The default document viewer in Ubuntu, eVince, is a nice application with fast loading times. It’s pdf rendering is pretty good too, and supports Full Screen as well as automatic scrolling. But eVince is not all that steady with all types of pdf documents. For the documents involving high resolution graphics, Images, forms etc, eVince tends to become sluggish and some times taking ages to load the document. For documents like these, we need to use an alternate pdf reader, and that’s where FoxitReader comes to play.

FoxitReader is a famous pdf viewer, most popular with Windows users. But it also has a linux native version (Not a ported version using Wine or something else), which is as fast as it’s windows version and contains all the basic features. The download page has links to .bz2, .deb and .rpm packages.

Go to here, and click on the “More Download” link in the Learn more column of the linux download table, and you can see the links for downloading the packages.

Google Chrome for Ubuntu Jaunty 9.04

June 7th, 2009
It’s all over the news! Google released an official developer build of it’s browser, Google Chrome for Linux. Pre-compiled .deb packages are available for download from here.

Even though Google cries foul about the instability of the package and says “Don’t Download Them”, I’ve been running chrome from past one hour without any glitches. The dev version lags many features including flash support, but it’s working great with normal sites. I’m able to use the google apps like GMail, GCal, GReader and other sites like Twitter, Orkut etc.

It’s a good thing Google isn’t porting the browser to linux… They are taking time and rebuilding the Chrome browser for linux. This helps in living up to the spirit of Chrome browser: Faster, Safer and Easier. If the application has been ported, it would’ve badly effected the speed as well as safety. Hope we would get an alpha version soon…

Google Squared! Reviews, Screenshots, Technology..

June 4th, 2009
Google came out with a new search tool called Google Squared. It “helps you quickly build a collection of facts from the Web for any topic you specify”, says the website.

This app is really cool and is innovative. From the website:

“For example, say you’re curious about which roller coasters are thefastest, tallest, and longest in the world. Until now, you would havehad to comb through dozens of webpages to compile the informationyou’re looking for. With Google Squared, all you have to do is type [
roller coasters ] into the search box to see an automatically generated table of roller coasters and their attributes.”

The home page is of Google brand (White background, No heavy graphics) very similar to the Google Search homepage, except for the suggestions of the latest/popular searches performed.

Here’s how the search results come up:

But there is more to the search results than what meets the eye. We have options to add more columns to the search results:

As you can see the ‘x’ marks on the columns already being displayed, clicking on them removes unwanted columns from your search results, giving you screen space to add more relevant columns. And more over, it improvises.. “Google Squared can learn from edits and corrections you make to your Square to gradually improve its quality for all users”.

And that’s just not the end of it.. You can save your sqaures, as well as you can share them with your friends… That’s really a nice feature! For example, Let’s say someone asks you suggestion for a Digital Camera, you sqaure the results, edit them according to your view points and send them the square for their pick. Nice!

And it crowdsources! You can participate in building it. If the app isn’t able to sqare about something, It will ask your help to build a square about the thing so that it can be of help to others. See the screenshot below:

The app is pretty basic and is in it’s infancy, making mistakes…

But hey, it’s capable of learning… :-)

So, how’s google doing this? From TechCrunch,

“Google is looking for data structures on the web that imply facts, and then grabbing it for Squared results. It takes an incredible amount of compute power to create one of those squares”

More about this way of presenting date, From TechCrunch:

“One of the next frontiers of search is taking all of the unstructured data spread helter-skelter across the Web and treat it like it is sitting in a nice, structured database. It is easier to get answers out of a database where everything is neatly labeled, stamped, and categorized.”

This is a new way of organizing information, and Google is open for thoughts and suggestions from public. Send them to labs+squared@google.com.
