Fedora Linux

# yum install kmod-nvidia

Each vendor's video control tools will be installed into the application menus. During the installation, the appropriate changes will be made to the Drivers lines in the X server configuration file /etc/X11/xorg.conf , and those changes will automatically be undone if the proprietary drivers are removed.

Each proprietary video driver requires a kernel module, so you may need to wait until a day or two after a new kernel is released before upgrading to that kernel. 

5.3.3.2. ...installing software to handle proprietary multimedia formats?

Software to play proprietary audio and video formats (such as MP3, WMA, and AVI) is available from the Livna repository. It is not included in Fedora Core because it does not meet the Fedora guidelines (either it is not open source, or it is patent-encumbered).

Once you have enabled the Livna repository, you can install a wide range of audio and video software and decoders (codecs) using the command:

# yum install '*mplayer*' '*xmms*' '*xine*'

5.3.3.3. ...excluding packages from management by yum?

To exclude packages from yum , edit /etc/yum.conf and add an exclude line. Here is an example (shown in bold); substitute globbing patterns (see Lab 4.3, 'Managing Files ') that match the packages you wish to exclude:

[main]
cachedir=/var/cache/yum
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
distroverpkg=redhat-release
tolerant=1
exactarch=1
retries=20
obsoletes=1
gpgcheck=1
exclude=*kernel* *xorg*
# PUT YOUR REPOS HERE OR IN separate files named file.repo
# in /etc/yum.repos.d

5.4. Rolling Back a Package Installation, Upgrade, or Removal

RPM has the ability to save datafiles before erasing them, permitting installations, updates, and removals to be undone through a rollback operation. Since it can take a substantial amount of space to save data necessary for a rollback, this feature is not enabled by defaultbut it's well worth sacrificing some disk space in most cases.

5.4.1. How Do I Do That?

In order to enable rollbacks, it is necessary to enable repackaging during the upgrading and removal of software. This can be enabled using command options, but the options have to be used consistently, and it's easy to forget them. Therefore the best approach is to configure both rpm and yum to use repackaging all the time.

To configure rpm , create the file /etc/rpm/macros and place this line in it:

%_repackage_all_erasures 1

To configure yum , edit /etc/yum.conf and add the tsflags ( transaction set flags ) line shown in bold here:

[main]
cachedir=/var/cache/yum
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
distroverpkg=redhat-release
tolerant=1
exactarch=1
retries=20
obsoletes=1
gpgcheck=1
exclude=*xorg* *xfree* *XFree* *kernel*
