The standard Trisquel distribution includes the MATE desktop environment and graphical user interface (GUI), and English, Spanish and 48 other localizations, 50 in total, on a 2.9 GB live DVD image.

[14] Triskel is another alternative to mainline Trisquel using the KDE graphical interface, available as a 2.3 GB ISO DVD live image.

[15] Sugar is a free and open source desktop environment designed with the goal of being used by children for interactive learning.

[16] The full installation includes 51 languages (Albanian, Arabic, Aranese, Asturian, Basque, Bulgarian, Catalan, Central Khmer, Simplified Chinese, Traditional Chinese, Croatian, Czech, Danish, Dutch, English, Esperanto, Estonian, Finnish, French, Galician, German, Greek, Hebrew, Hindi, Hungarian, Indonesian, Irish, Italian, Japanese, Korean, Latvian, Lithuanian, Low German, Norwegian Bokmål, Norwegian Nynorsk, Occitan, Punjabi, Polish, Portuguese, Romanian, Russian, Serbian, Slovak, Slovenian, Spanish, Swedish, Tamil, Thai, Turkish, Valencian and Vietnamese) pre-installed in a downloadable 1.2-gigabyte DVD image.

The answer I came to when running Trisquel 7.0 is that, yes, the distribution appears to be nearly as capable as operating systems that do not stick to the FSF's definition of free software.

Some people who use hardware that requires binary blobs or non-free drivers may face problems and Flash support isn't perfect when using the free Gnash player, but otherwise Trisquel appears to be every bit as functional as other mainstream Linux distributions.
