Browser plugin is disabled on my system, however as someone who has written Android apps and continues to use Eclipse to work on my Computer Science degree... I still instantiate my fair share of Java classes on my computer. I am definitely more of a fan of the brewed version of java rather than Java the programming language or the VM environment that is called Java.
How about something from the 25th lesson? http://nehe.gamedev.net/data/lessons/lesson.asp?lesson=25 The implementation of CreateGLWindow() is very windows specific, and from what I've looked at, there doesn't seem to be a tutorial for a Linux/X11 nor a SDL specific implementation, they do have GLUT for OS X and Solaris.. However, actually creating a window and polling for key input is very platform-specific with NeHe's tutorials, which may be why the OP was asking for tutorials specific to Linux.
