Adding a software repository from Ubuntu PPA in Ubuntu Karmic and later

This new method is easier than the old one which required you to edit your software sources manually, and then get the key and import it. The new one is as follows:

1. Go to the PPA page of your interest, e.g. URL, check the name of the new repository, it is "ppa:transmissionbt/ppa" in my example.
2. Open a terminal and type "sudo add-apt-repository ppa:transmissionbt/ppa"
3. Done! This both adds the entry to your software sources list as well as importing the key which authenticates that repository.
4. Don't forget to refresh your repository to be able to update/install new packages "sudo apt-get update"

PPA = Personal Package Archives, i.e. the user-contributed software repositories.

Workaround for Ubuntu Karmic Bug: Window List buttons do not always respond to mouse clicks

Here is the bug URL

I got the solution from there as well, as this was an extremely annoying bug for me and I consider it a FATAL One!

Open a terminal and run the following command:

"nohup env GDK_NATIVE_WINDOWS=1 gnome-panel --replace &"

Where:

"nohup": To run the command independent from the terminal, so as not to cancel the action if the terminal is closed.

'&': Must be put at the end of a command run using "nohup" to run it in the background and avoid canceling the command.

That's it!

The above command will restart the "gnome-panel" and you'll find that the bug disappeared.

I haven't restarted my machine yet to know whether this command is persistent or not (I think not), but anyway it can be easily put in the session startup if it's not.

Thanks go to "schuetza" who suggested this nice workaround on the original bug report.
