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.).
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
2) To check the process id of jockey
ps -e | grep jockey
In mycomputer the Output: 1783 pts/0 00:00:00 jockey
remember the process id(1783)
3)Type the following to stop/kill the process
sudo kill -9 [process_id]
sudo kill -9 1783
