Today I tried to install fonts for GNome desktop and unable to install due yum lock in my server that is load with centos
[root@localhost ~]# yum install xorg-x11-font*
Loaded plugins: fastestmirror, refresh-packagekit, security
Existing lock /var/run/yum.pid: another copy is running as pid 2600.
Another app is currently holding the yum lock; waiting for it to exit…
The other application is: yum
Memory : 21 M RSS (1.2 GB VSZ)
Started: Mon Oct 14 12:19:29 2013 – 08:47 ago
State : Sleeping, pid: 2600
First i attempt to kill the process
# kill -9 2600
the process could not be stopped
Second i attempt to kill all yum process
# killall -9 yum
still the process could not be stopped
then i shutdown my server and switched on again and still the same result.
finally i remove the yum.pid 2600
after this yum started working fine.
Final solution if you fail to stop the process :
#rm -f /var/run/yum.pid 2600
then update your yum
# yum -y update
Make sure that yum-updatesd is started :
# /etc/init.d/yum-updatesd start

To resolve this key problem in RHEL, I installed the public release key
#rpm –import /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
This allows you to install from the local source.Copy and install all the packages from the RHEL5 DVD’s to a directory to use ‘YUM’ from local repository.
Importing the key as outlined above enabled me to install the packages without getting the following error:
warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID 37017186.
Note : RHEL DVD’s help me in completing the installation in local server without internet connection.

It is very easy and simple to install Compiz & Compiz Fusion plugins on Lucid Lynx.
Just Click Application —> then Ubuntu Software Center
Ubuntu Software Center pop up
Search for CCSM
Click install and then give the root password to install CCSM
After the CCSM installation completed, install Nvidia drivers
Click System –> Administration –> Hardware Drivers
Then the system searched for available drivers and i choosed the recommended Nvidia accelerated graphics driver (version 173) option from the list and then activated the driver by clicking Activate button.
Restart the system, so that the new nVidia graphic display driver will be ready for use.
Then enabled the desktop effects by clicking System –> Preferences –> Appearance and on the –> Visual Effects tab, selected Normal .
After this installation my desktop looks great, very much happy to use Desktop effects in Ubuntu 10.04.
After reading this you too will be enjoy using Compiz & Compiz Fusion plugins in Ubuntu 10.04 (Lucid Lynx).
