Scriblly is a simple Adobe Air application which enables user to write a quick note, and send it to a certain email. I tried to test it to be a blogging tool, but it failed to be a quick blogging tool is combined with "Blog by Email" feature. The tool doesn’t allow user to define a certain sender email, which is then refused by the receiving blog which expects the sender email to be a the blog owner email.

In addition, the format of the created note is not good, there is no place for note header and there is no formatting options.

Anywhere, the tool can be found here: http://www.adobe.com/cfusion/marketplace/index.cfm?marketplaceid=1&publisherid=12118&event=marketplace.offering&offeringid=15420

Add the following lines to your /etc/apt/sources.list:

deb http://ppa.launchpad.net/siretart/ppa/ubuntu jaunty main
deb-src http://ppa.launchpad.net/siretart/ppa/ubuntu jaunty main

Import the appropriate GPG key (port 11371 on your firewall must be open to use the keyserver):

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 0xce90d8983e731f79

See https://help.launchpad.net/Packaging/PPA#Adding%20a%20PPA%20to%20your%20Ubuntu%20repositories for additional information how to add GPG keys to your system.

Install the driver:

$ sudo apt-get update
$ sudo apt-get install xserver-xorg-video-intel-2.4

Now you should be set. Restart X by running “sudo /etc/init.d/gdm restart” in a terminal and see if the graphics performance from intrepid is restored.

Do I need to change my xorg.conf file? ==> May not work. Situation not improved without xorg.conf change??

Rolling back

If the driver does not work for you, or is not better, you should rollback to the original Ubuntu one. Remove the two lines from /etc/apt/sources.list again, and install the original one again:

$ sudo apt-get install xserver-xorg-video-intel

If X.org does not start at all, you should change to a text terminal by pressing Ctrl+Alt+F2, logging in, and use “sudo nano” to edit /etc/apt/sources.list. After installing xserver-xorg-video-intel, restart the computer with “sudo reboot”.
