While Razer has yet to open-source their drivers or provide official specifications, like past Razer mice the DeathAdder had functioned without fault as a mouse under Linux. However, the user then lacks the ability to change polling rates, profiles, and other options. RazerTool is a viable SourceForge project for adjusting these settings on the Copperhead, but its support does not appear to be completed yet for the DeathAdder. Using a SVN checkout of RazerTool, the DeathAdder had not yet worked. However, it should take minimal hacking to add the support to RazerTool.
We had tested the Razer DeathAdder out for a few weeks with Linux inside GNOME and running a variety of workstation/business programs as well as a few games. The mouse had operated fine without any complaints while running Enemy Territory and Quake 4 as well as when using OpenOffice, Thunderbird, and Firefox.
While testing the Razer DeathAdder, the thought had occurred what we like better whether it would be the prestigious Copperhead or the new DeathAdder. The DeathAdder's design is larger and different in many respects from the Copperhead while it continues to improve upon Razer's mouse technology. We had actually liked the slight increase in the size and its overall ergonomics. After weeks of testing, the Razer DeathAdder is our new favorite and will be taking home the Phoronix Editor's Choice Award for its superior design and quality. This is also a competitively priced mouse at approximately $60 USD.
