Customizing the splash image in GRUB

Got bored with corporate logo of your Linux distribution?

Change it..

1.The image should be of size 640x480 pixels

2.Should only have 14 colours

3.In gzipped xpm format

You can use GIMP for these modifications and save it as xpm file. Then gzip and make it splash.xpm.gz

RPM Fusion.. Resources are Unlimited....

Multimedia on CentOS 5

Step 1: Add the RPMforge repo (needed for majority of multimedia files)

rpm -Uhv http://rpmforge.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.3.6-1.el5.rf.i386.rpm

Step 2: Add the Macromedia repo (optionally needed for flash)

rpm -Uhv http://linuxdownload.adobe.com/adobe-release/adobe-release-i386-1.0-1.noarch.rpm

Step 3: Install multimedia applications (command line to install required packages)

yum install libdvdcss libdvdread libdvdplay libdvdnav lsdvd mplayerplug-in mplayer mplayer-gui compat-libstdc++-33 flash-plugin gstreamer-plugins-bad gstreamer-plugins-ugly gstreamer-ffmpeg libquicktime

Step 4: Installing w32Codecs (required for xvid and other proprietary formats)

wget www1.mplayerhq.hu/MPlayer/releases/codecs/mplayer-codecs-20061022-1.i386.rpm ; rpm -ivh mplayer-codecs-20061022-1.i386.rpm
wget www1.mplayerhq.hu/MPlayer/releases/codecs/mplayer-codecs-extra-20061022-1.i386.rpm; rpm -ivh mplayer-codecs-extra-20061022-1.i386.rpm

You should now have full multimedia and video support for most popular formats.
