I have recently downloaded the Nexuiz all platform zip from sourceforge.net and the exe runs under windows without any pain. But I am failing to get things running under linux. Whenever I run nexuiz-linux-sdl.sh or nexuiz-linux-glx.sh my system restarts. It doesn't restart with compelte shutdown rather it simply logs out and shows up the login screen very quickly (much quicker than a normal restart should take).

More info if helps - I am running other games (for example Battle for Wesnoth) under my linux system successfully.
