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
