Uyarı! Do not add external links to software packages that contain illegal software. Since openSUSE is sponsored by Novell, this means "illegal" in any jurisdiction that Novell carries on business. Discuss this page

Legal restrictions prevent various packages and formats openSUSE users frequently request to be included in openSUSE from being distributed. This page is intended to be an explanation as to the reasons and issues that surround these packages and formats that prevent their inclusion and/or distribution by openSUSE.

openSUSE supports the use of Free/Libre Open Source Software. The retail version of SUSE may include additional packages that have been licensed by Novell for distribution.

The software that may not be distributed by openSUSE is the following:

  • Proprietary software
  • Patent-encumbered software
  • Any software that violates the laws governing software distribution in any jurisdiction Novell conducts business in.

Some proprietary software and drivers may be available from their respective owners and licensed vendors.

Illustration

DVB TV viewer

Suse 10.0 (and other versions) do not allow DVB viewing, because the required decoder is not included in the distribution. Despite kaffeine and xine are included in the distribution, they do not include the required decoder modules.

DVD Video

Legal Issues

DVDs are encoded in mpeg2-video, for which there is no support in the current SUSE Linux OSS release, due to the mpeg2 format being patent encumbered by its owners, Moving Picture Experts Group (MPEG). The patent holder is unwilling to offer an unrestricted patent grant, as required by the GPL.

In addition region-coded DVDs are encrypted with the Content Scrambling System (CSS).

There is an opensource project called libdvdcss that bypasses this encryption. Though the encryption is weak, using any method or device to bypass this is classed as a 'circumvention device' in countries such as USA & Australia and is illegal.

Possible Solutions

In some countries it is legal to backup your own DVD.

If you do not require compatibility with a DVD player, consider encoding your own videos in Ogg Theora. XviD is another format that may be used, though it is an mpeg-4 based format, and may or may not suffer from the same legal issues.

Mpeg-2 encoder and decoder cards exist with driver support for Linux provided by the manufacturer and distributors. While they may or may not work specifically with openSUSE, they are a legal and licensed way of acquiring mpeg-2 playback on your Linux PC. If the DVD is unencrypted, this will make playback available.

MP3

Legal Issues

Even though MPEG Audio Layer 3 (MP3) is an ISO standard it is not a free and open standard and is covered by numerous patents. It is not legal to distribute unlicensed MP3 Decoders and Encoders in most countries.

Possible Solutions

Novell has a contract which allows to provide mp3 support via the RealPlayer. It can be used via amaroK or banshee. RealPlayer is not open source, so you have to add the http://download.suse.com/10.0/SUSE-Linux10.0-GM-Extra/ to your YaST sources and install either amarok-helix or banshee-helix to get mp3 playback support in these applications.

As an alternative, enocode your audio files in Ogg Vorbis, FLAC, Speex, or other such freely used and available audio codecs. Please see their respective pages for further information.

NTFS

Legal Issues

NTFS is solely owned by Microsoft, and is highly patent encumbered. Software exists to read and write to NTFS formatted disks, but are considered illegal in many jurisdictions.

Many support the use of FAT/FAT32 to share files between Windows and Linux on a single system. As Microsoft's patent on FAT has been upheld as of January 2006, long filenames on FAT partitions may not be used, as they are patent-encumbered.

Possible Solutions

It is preferable to use a file system natively supported by Linux, such as ext3 or reiserfs. F/LOSS software exists for windows which will make use of various Linux-supported and originating file systems. To share these drives, format them using an available and eligible supported file system.

Ext2 IFS is a "freeware" (not free software) installable ext2 file system for Windows. It integrates with the Windows kernel thereby providing access to files on ext2 (and ext3) partitions seamlessly to all applications.

explore2fs supports ext2 and ext3 from within Windows.

Samba enables your system to access file shares on networked Windows systems, and to act as a server for Windows systems.

NVIDIA Graphics Drivers

Legal Issues

The NVIDIA graphics drivers are proprietary and many kernel developers consider this driver to violate the GPL. license of the kernel.

Possible Solutions

Official drivers are available from NVidia.

X.org includes the F/LOSS (Free/Libre Open Source Software) NV driver for many NVidia graphics adapters. This is used by default.

Consider the use of a graphics adapter with full support for Linux and F/LOSS software, such as from Intel.

ATI Graphics Drivers

Legal Issues

The ATI graphics drivers are proprietary and many kernel developers consider this driver to violate the GPL. license of the kernel

Possible Solutions

Official drivers are available from ATI.

X.org includes F/LOSS drivers for many ATI graphics adapters. These are used by default.

Consider the use of a graphics adapter with full support for Linux and F/LOSS software, such as from Intel.
