Ubuntu 11.10 keep Waiting for jockey-backend to exit

I have this problem twice, that after a fresh install of ubuntu 11.10, it is having problem updating software cache. Whenever I tried to run Update Manager, it will pop out a message box saying "Waiting for jockey-backend to exit". I believe this is a bug of ubuntu 11.10.

I found the solution for this problem from http://naveenubuntu.blogspot.com/2011/09/waiting-for-jockey-backend-to-exit.html, and you simply need to follow these few steps to manually end the jockey-backend and allows your ubuntu to update software cache.

What is jockey-backend ?

Jockey is a tool for installing third-party hardware drivers.

Jockey provides the infrastructure and the user interface for finding and installing third-party drivers which are applicable to the computer. This includes drivers which are added or updated after the release of a distribution, or drivers which cannot be included into the distribution for various reasons (CD space limitation, licensing problems, etc.).

Solution :
You only need jockey for enabling restricted drivers, afterwards you can safely disable it.

Open Terminal and type following commands:

1) To get into root mode
    sudo -i

2) To check the process id of jockey
    ps -e | grep jockey

Output: 2982 pts/0 00:00:00 jockey

remember the process id(2982)

3)Type the following to stop/kill the process

  sudo kill -9 [process_id]

 sudo kill -9 2982

  1. "Which Forex pair and time frame is best to trade" is the frequently asked question and I want do give you the DEFINITE ANSWER.

    Are you expecting that I am going to say something like EUR/USD on 5-minute time frame or GBP/USD on daily...? No, it is not so simple, but SIMPLE ENOUGH we can figure it out!

    The "PROBLEM" is that markets change over time. If GBP/USD was a well trending currency pair a few years ago, today it is another one.

    I actually want to let you know about a SPECIAL TOOL that I use to find the BEST TRENDING PAIRS among all the Forex pairs.
