Tux Magazine was a Linux magazine aimed at Linux desktop end users, specifically those who use the KDE desktop environment. Tux's mission was to help Linux take over the desktop market. Tux was not a print magazine: each issue was delivered digitally as a PDF file. The first issue was published in March 2005 and further 19 issues followed almost every month. On January 1, 2007, the publisher announced that the December 2006 issue was the last for the moment, because financial and other issues required a re-evaluation of how to best serve the reader community.

All 20 issues were laid out in a style usual for glossy printed magazines but optimised for screen reading. The magazine fits perfectly on displays in the 4:3 landscape format and the files open automatically in full screen presentation. The number of pages per issue are between 46 and 60 with almost no advertising; the files sizes range from 1.8 MB to 14 MB with an average of about 4 MB.

TUX Magazine contained HOWTO-type articles which helped new Linux users to use their Linux system in their everyday life. The magazine also had reviews of Open Source distributions and software/hardware products aimed at end users. In this, TUX was different from many other Linux Magazines which normally focus on a much more experienced audience.

TUX Magazine elected to focus primarily on the KDE desktop because the publishers regarded KDE as being more comfortable for computer novices and newcomers to Linux. In addition, a survey showed that more newcomers used KDE than GNOME. TUX Magazine was sometimes criticised for focusing on KDE and being critical of GNOME, especially in editorial style columns such as Mango Parfait's. This contained provocative humor which was not well received by GNOME users.
