Problems in upgrading Ubuntu 9.04 from Ubuntu 8.10 in Virtualbox

Posted by Bala on August 20, 2009

I have using Virtualbox for more than 6 months and I was satisfied to use it. I was using my Virtualbox with Ubuntu 8.04 LTS. Yesterday I added one more virtual machine with Ubuntu 8.10 since my Ubuntu 8.04 was crashed and unable to recover. After installing Ubuntu 8.10, I have installed VBOXGuest Additions and after that I have updated to Ubuntu 9.04. When restarted the system after the upgrdation is done, I got the following error:

Ubuntu is running in low-graphics mode

The following error was encoutered. You may need
to update your configuration to solve it.

(EE) module ABI major version (4) doesn’t match the
server’s version (5)
(EE) failed to load module “vboxvideo” (module requirement
(EE) No drivers available.

After googling, I have found the solution from Virtualbox Forum. Steps to follow to get back the normal smooth booting.

– select the offered low resolution startup mode,
– Ubuntu will complain that something is on display:0 and it will try to start the x server on display:1
– accept it, Ubuntu starts
– install Guest Additions,
– and finally restart the operating system.

To avoid this you can reinstall Guest Additions first before restarting the system after successful upgradation.

Sometimes, even the above steps will not come because of misbehaved UI. So, in that case, you can have do the installation from CLI. Follow these steps,

1. sudo apt-get install build-essential linux-headers-generic

2. sudo mount /dev/scd0 /media/cdrom

3. sudo sh ./

Finding a font from image

Posted by Bala on August 19, 2009

Its almost a year i have blogged. Now I am thinking about blogging small tips on computers which learn day to day for my use and in that list this is going to be my first blog entry.

Most of the times when browsing through any site I have been attracted by the Header images which have been used. But it will be very difficult to find the font used for the same. Stuck up with a same situation yesterday, I googled and found the site WhatTheFont. In this site you can find the font used for text in the image in 3 easy steps. The good thing about the site is that if the system doesn’t finds a exact match for the font, it will show the closer match for the same.

Step 1: Upload the image to the site for which font needs to be identified or provide the URL for the image

Step 2: The system will identify the letters in the font and provide you a list, you have check whether the entries are correct and some times you may be asked to enter the characters to identify.

Step 3: Once identification of letters, is complete and submitted, the fonts matched for the image will be shown.

Not only the exact matches it will also show the matches closer to the image. This help us to find even more better fonts and you can buy from their site if you need those fonts 🙂

And if you are not able to find any fonts of your choice you can use their WhatTheFont Forum (I haven’t used their Forum)

Thanks to PKP for referring this PicLens application in his blog.

PicLens, an Addon application, provides an immersive full-screen experience for viewing photos and videos on the supported sites listed below and on sites that support Media RSS.

It supports most of the sites which provides Media RSS. Some of the popular sites are Picasa, YouTube, Flickr, Phoyobucket, Google Images Search,  Yahoo Images Search etc.
